	How's the progress coming along? I'm guessing the HD 7770 is being tested in-house. Thanks. http://www.gpugrid.net/forum_thread.php?id=2778

	Sounds fishy. Somehow feels like a scam. Didn't expect this from medical boinc project. I think i will quit gpugrid and move to other projects untill they too start to try make money out of crunching power. Can you please clarify what you mean by "Sounds fishy" and "Somehow feels like a scam"

	HI Steve. We will add that this is using BOINC. I did not understand your first point. thanks The Project says: You don’t gain bitcoins in this project. was my 1'st point. Maybe the GPUGrid Project gets the BitCoins ??? but from what I read the Participants don't. Not that that bothers me as I don't have anything to do with BitCoins anyway, at least not at this time anyway ... ____________ STE\/E

	If I understand correctly this is just a testing phase to get the project started. I don't think they will actually get BitCoins until the bugs are ironed out (I could be wrong).

	For me the bitcoin network is an impressive idea. Read about it: http://bitcoin.org/bitcoin.pdf I understand that somebody might want to do scientific calculations instead, that's why we kept it separate. So you can choose to participate. It's very different from molecular simulations of course. gdf But the Project it's self say's you won't be getting any Bitcoin's ... Also other than saying it gives BOINC Credits no where at or on the Site does anything indicate it's a BOINC Project, at least I couldn't find anything ... What is donate@home? Your compute time will support science and at the same time participate to the bitcoin experiment. You don’t gain bitcoins in this project. You do receive BOINC credits which have only a symbolic value of your participation. So, the only reason to participate is to make a difference, nothing else is gained. You might also want to volunteer your computing time to do scientific calculations, then give a look at gpugrid.net ____________ STE\/E

	I'll give it a try. There are still bugs in the other projects that refrain me from running them 24/7 so it can't hurt.

	It's a nice idea, but I'd rather donate my GPU resources in a more "scientific" way through GPUGRID. I'll run other projects (Milkyway, POEM) on my 7970 until GPUGRID is ready.

	Big Question at the Projectteam here: Did you test AMD APP SDK with FFToptimized API ( http://developer.amd.com/libraries/appmathlibs/Pages/default.aspx ) AMDs current GPUs should crunsh nVIDIA without any problems like they do on: - Collatz - Milkyway - POEM - Einstein@Home Beta called Albert@Home By the way if OpenCL is the problem - use the working one : CAL It would be easier if you would allow external developer so people like Gipsel could help ...

	I do not intend to spend countless €s on new state-of-the-art GPU hardware every year just to be able to run your project! Christopher, there are plenty of low cost options for running GPUGRID if you really want to. I recently bought a b-stock GTX275 SC from EVGA for < $150 shipped. Damn thing gets ~100K/day as long as my network's not futzing out. I've seen GTX260s on e-bay for as little as $40, and they're good for 45-50K/day (maybe more). My point is that with a little looking, one doesn't have to spend much at all to volunteer here. But if you're just dead set on running AMD and nothing else, I'm afraid you're going to have to be a little more patient. Cheers!

	A project that thinks its volunteers can afford high-priced high-end cards every year, is severely mistaken, has lost it and obviously is living in a dream world! You are the one living in a dream world. They don't think volunteers can afford expensive cards every year. The reason they will not support the current crop of AMD GPUs is because they cannot get their algorithm to work well on it. It does not matter how many other projects have their code running on AMD, the only thing that matters is the fact that the GPUgrid code does not run well on current AMDs. Maybe with more time and effort it could be done but the developers have made it clear they have invested all the time and effort they can. You have to get used to the idea that project admins are not born to serve us and cater to our demands to make their project run on our hardware and no amount of whining and bellyaching from you is going to change that. Accept it like an adult and move on. I do not intend to spend countless €s on new state-of-the-art GPU hardware every year just to be able to run your project! You don't have infinite amounts of money and they don't have infinite amounts of time. Yet you expect them to spend countless hours developing for your hardware! That isn't the way the world works. Successful people know when it's time to stop flogging a dead horse and move on. As far as GPUgrid computations are concerned, your AMD is a dead horse and it isn't going to run no matter how hard you/they flog it. It's time to bury the horse and move on to something productive. And btw regarding that there has allegedly not been enough time to take care of this matter earlier: was the new website REALLY that important for the project or the science? The old one did it for me personally quite well IMHO. The old website and server sucked. This one is much better and the time they invested in that was well spent. Sorry, this becomes frustrating and unnerving! Every new post in here makes one think: "Oooh, now there is good news!" and the news just go from bad to worse! Awwwwww! I'm so sad for you. Maybe in the future the developers should just say nothing about anything they try just so you won't be disappointed? Do you promise to then say nothing concerning the fact the developers say nothing? Have a nice Christmas though and I hope Santa is putting a thousand brand new, top model AMD Radeon HD 7990 under your Christmas trees even before release date, or however the enthusiast card will be named then! ;) Merry Christmas. I hope Santa brings you one too. Ban me, if you must, for I am beginning to not care anymore! Do you think we care that you don't care? The only one you seem to care about is you. You don't care about what the devs have tried to do and why it won't work. Why should anybody care about you not caring?

	I have two fairly newish AMD Radeon HD 6990/ATI Radeon HD 5970 cards here, that of course do well on other projects, but will supposedly not here... If you want to contribute to this project so badly, should't you have bought a couple of not so high end nVidia cards (GTX 470, 570) instead? A project that thinks its volunteers can afford high-priced high-end cards every year, is severely mistaken, has lost it and obviously is living in a dream world! You are obviously mistaken. You have a card like that, but from the wrong vendor. Why not simply making the prerequisite of a working quantum computer, if you want to sort out only wealthy gals and guys? I do not intend to spend countless €s on new state-of-the-art GPU hardware every year just to be able to run your project! Your frustration speaking. I guess you would be equally frustrated from a ridiculously performing AMD client. You can use well your AMD cards elsewhere, so there is no loss from scientific point of view. And btw regarding that there has allegedly not been enough time to take care of this matter earlier: was the new website REALLY that important for the project or the science? The old one did it for me personally quite well IMHO. This is a selfish point of view. Maybe the old server software and website didn't do so well for the project. Sorry, this becomes frustrating and unnerving! Every new post in here makes one think: "Oooh, now there is good news!" and the news just go from bad to worse! See this post. Ban me, if you must, for I am beginning to not care anymore! AMD should be banned for making their customers believe that their GPUs can do everything that nVidia GPUs can. However they will catch up with their new GCN architecture.

	Hi, let me clarify because I see that there are a lot of people that would like to use their cards and fear that they cannot. I am not saying anything new and we are not working against you, but with you. 1) Bad, well known news. The VLIW5/4 AMD cards are very powerful cards and usually cheaper than nvidia, also the top cards beat nvidia in terms of raw performance. However, only very numerical intense algorithms can benefit. For gpugrid, a top VLIW5 card consumes almost like a gtx580 but has a performance of a gt8800, a card of several years ago which is not recommended. It's not a decision, there is nothing we can do about it and we tried a lot. Other algorithms are better with this and electricity costs 3 times the card. 2) Good news, to be confirmed. In the future, new Amd cards based on GCN should level up with Nvidia fermi/kepler. We could not check it but all the indications are good. So take this with a level of uncertainty. Expect to have an equal representation of nvidia and amd at gpugrid in the future. This will be great because half (or more) of the world cannot crunch for us now. In the past few months we have spent plenty of hours to prepare for AMD. Of course, don't go and buy a new card because of this! The HD7950 is expensive because now it's the fastest card worldwide. It will cost 100USD or less as soon as nvidia wakes up with kepler. There will be other reduced GCN cards also cheaper and less power hungry. According the news websites, AMD will put out all the new cards within 6 months, so there should be plenty. We only have a single VLIW5 card now. That's all. Maybe soon a GCN card. We will test on those. If it works, meaning it is really stable, the application will go out. If you want to use it on VLIW5 do it, but your are not using it for its capabilities here and there is nothing, absolutely nothing we or amd can do about it. Enjoy holidays and merry Christmas. gdf

	I'm far from disappointed or frustrated; I was holding onto an HD5850 in the hope I could use it here, but now that POEM has launched an AMD GPU app, I am delighted I can use it there on a Bio-science project, somewhat similar to this project. Even if GPUGrid launched the AMD app, I don't think I would want to use it here - well not if it would only contribute 1/8th the performance of a comparable NVidia GPU, and we are talking about a 2088GFlops GPU performing like a GT240, and not if the performance at POEM is 4 or 5 times better. Performance is very much down to the research requirements, and GPUGrid does some of the most complex GPU research anywhere. You have a GTX 480 running here, and doing good research. Be happy with that, and use your AMD GPU's at POEM. GDF and the other researchers/developers have to make decisions like this. They have limited numbers and resources, so if they feel now is not a good time to launch an AMD app (due to poor performance, numerous bugs over several generations, and other projects) then I can live with that. The time and effort required to facilitate and support a poor performing app is probably not worth it. Kepler is also coming out soon, and the team has to prepare to facilitate those cards, and they will probably be twice as fast at crunching. A lot of effort went into testing both a new server system and site. Other ongoing considerations include new apps, and better recognition systems. The site definitely needed an overhaul and in my opinion has resolved many issues and made many significant improvements. The server upgrade simply had to be done. I will not be rushing out to buy a 7950, and I would not suggest anyone else does - they will be too expensive, for me, and who knows what the performance will be like. Six months or a year from now, when we know what the performances are and cost relative to comparable NVidia cards, then perhaps I will get one, or perhaps I will get one for another project, POEM, or possibly WCG. PS. Nobody is getting banned for speaking their mind. If you say it like you see it, keep it clean, and don't attack anyone, I have no issues. Throw a wobbler and crazy posts just get deleted, not your account. Have a good Christmas. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help

	Well, if this should or will indeed be the final verdict here, then this will be it for me! If that is all, you were able to conclude in around two years, then this is disappointing and poor!

	We never tested on VLIW4. Yet, I would expect marginal improvements compared to VLIW5. It's not just a problem of VLIWX, there are many more problems in those cards for compute. As I said as long that older cards are stable, we can support them. What we cannot support is too many generations because each one comes with their bugs. The more bugs there will be, the less we can support. A VLIW5 card would probably be 8 times slower than Kepler (consider the save in electricity). gdf

	Probably doesn't mean definitely. So no GCN for 7800 series, fair enough. That changes the picture, for me. In Jan there would only be two very expensive GCN cards. Don't know how worth while it would be supporting a project with say ten 7900 GPU's attached? As for that wiki page, I have my usual doubts about it's accuracy. My take on things is that the initial 7000 release will use GDDR5, and not XDR2? If so, and if future cards will use XDR2 then is it also possible later editions of the 7800 will be released with GCN? Will the 7800's use VLIW5, just like the present (40nm) 7600M cards, and will it be any better than VLIW4 and VLIW3? Was the AMD app ever tested on VLIW4 and VLIW5 GPU's? ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help

	GDF made the decision that GPUGrid will only try to use GCN based AMD GPU's due to the relatively poor performance of existing AMD models (up to and including the 6000 series), and presumably logistical reasons. Basically, this will limit any GPUGrid app to the high and probably mid range 7000 series AMD GPU's; Radeon HD 7970, 7950, 7990 and probably 7870 and 7850. I doubt if the intermediate 7770 and 7750 GPU's would be usable (depends on performance/GCN). Obviously testing can't happen until the GPU's have been released and the researchers have a GPU to test. STEVE pointed out the high costs, 'over $500 for the 7970'. Good point, there might not be a massive demand for an AMD app. I suspect cards might trickle out in pairs rather than all get released at once and the 7990 is not due until March. As pointed out you can now use your old and present AMD GPU's at POEM. 4000 through to 6000 series. Requirements are Boinc Beta version 7.x and I think Catalyst 11.x drivers. Works for Linux and Windows and is OpenCL. You're wrong. http://en.wikipedia.org/wiki/Comparison_of_ATI_graphics_processing_units#Southern_Islands_.28HD_7xxx.29_series The only cards that will support GCN will be 79x0. Just like 69x0 were the only ones from the 6xxx series that supported VLIW4. From my point of view, if poem did it, if folding did it, if wcg (most probably) did it, why couldn't gpugrid not do it? I would have preferred to have a low gpu utilization just like over at folding, instead of not heaving any app. The guys from SETI faced the same problem, but they bypassed by running two applications simultaneously. I actually would have wanted a low utilization since I would have let the app running non-stop while also doing other stuff on the computer. All I can say is ...¡Feliz Navidad! and see you in 1 year+, when the new fusion series is release which, hopefully, will have GCN on it.

	HI, just to specify we still have not tried any GCN based card. We expect to be good, but don't have any number, nor we know if it works at all. We have amd to send us one, let's see. The code is ready, so as soon as we get one in, we should be able to send out the numbers. Looking at the numbers on compute published by some sites, I still expect kepler to be faster, but probably quite close. gdf

	GDF made the decision that GPUGrid will only try to use GCN based AMD GPU's due to the relatively poor performance of existing AMD models (up to and including the 6000 series), and presumably logistical reasons. Basically, this will limit any GPUGrid app to the high and probably mid range 7000 series AMD GPU's; Radeon HD 7970, 7950, 7990 and probably 7870 and 7850. I doubt if the intermediate 7770 and 7750 GPU's would be usable (depends on performance/GCN). Obviously testing can't happen until the GPU's have been released and the researchers have a GPU to test. STEVE pointed out the high costs, 'over $500 for the 7970'. Good point, there might not be a massive demand for an AMD app. I suspect cards might trickle out in pairs rather than all get released at once and the 7990 is not due until March. As pointed out you can now use your old and present AMD GPU's at POEM. 4000 through to 6000 series. Requirements are Boinc Beta version 7.x and I think Catalyst 11.x drivers. Works for Linux and Windows and is OpenCL. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help

	I'm still hoping to get some wu's for my AMD-Cards ... Was ist neu im AMD APP SDK V2.6? Key features supported in SDK 2.6 and the Catalyst 11.12 drivers include: OpenCL runtime integration into Linux and Windows® Catalyst drivers. Inclusion of the Khronos C++ wrapper API. Multi-GPU support on Linux platforms. PX5 support. Preview: Support for AVX instructions on CPUs that support AVX. Support for FMA4 instructions in OpenCL built-in function libraries on CPUs that support FMA4. Kernel reflection, query kernel parameters, and enable use of OpenCL kernels in data-driven applications. Support for atomic counters on APUs. Redesign of OpenCL run-time on CPU, significantly improving performance. Support for the cl_amd_media_ops2 extension, exposing hardware capabilities for accelerating image-related processing. Async copies preview (set environment variable GPU_ASYNC_MEM_COPY=2 to enable). The OpenCL 1.2 preview includes the following capabilities (requires 8.93.10 preview drivers): Host access flags for memory objects enables more efficient buffer handling. Pattern-based GPU buffer and image initialization eliminates need for certain buffer/image transfers. Memory objects migration supports early transfer of buffers in preparation for when they are needed. New generalized image creation API. Enhanced image/buffer map operations. OpenCL 1.2 CPU device partition, including partition of a CPU after addition to a context. Generalized 1D and 2D images, image arrays, and image <--> buffer interop. The 8.93.10 preview drivers also enable use of the static C++ kernel language. gDEBugger version 6.1 is a major improvement in performance and robustness over version 6.0. It can be downloaded for use with this SDK from http://developer.amd.com/gDEBugger. Integrated with Microsoft® Visual Studio Release Notes APP KernelAnalyzer v 1.1: Support for AMD Radeon™ HD7000 series GPUs (compilation only, no analysis). Support for Catalyst revisions through 11.11. Support for compiling kernels with the installed driver (select Installed Driver under the CAL version in the Options panel). Format and Target Object Code are now separated. APP Profiler v2.4 includes several key new features, including: A kernel occupancy analyzer that estimates, for each kernel dispatch, the number of in-flight wavefronts on a compute unit as a percentage of the theoretical maximum number of wavefronts that the compute unit can support. In addition to reporting the occupancy percentage, the profiler can display a report that can help the developer achieve a higher occupancy percentage. The ability to navigate from the API trace to the source code that called an OpenCL API. Improved OpenCL API analysis that provides performance suggestions to the developer. The ability to filter which OpenCL APIs are traced. Several UI enhancements, including the ability to rename sessions from the Session Explorer Window, and the ability to automatically delete Profiler sessions when closing a Microsoft Visual Studio solution. Preview: Support for profiling with AMD Radeon HD 7000 series GPUs (requires AMD APP SDK v2.6 and an AMD Catalyst version that supports this hardware). Hope that helps!

	We simply have not resources to take on the debugging on all VLIW4 AMD cards. The present and the future is GCN. Then, if it happens a miracle and the stability of VLIW4 is good, then we can also release for that. But again, running gpugrid on VLIW4 cards is very inefficient. gdf

	Performance of alpha versions has been pretty lacking compared to what's possible on nVidia hardware. Folding@Home is facing a similar problem. The current ATIs are hard to utilize effciently. GCN is changing this, it should be approximately equal to Fermi in terms of flexibility. If any ATI can be useful here it's GCN. Rumored launch is in 4 days, or maybe the 9th january.

	Either give your volunteers a definitive date when there will be an app, and I mean definitive, or a definitive statement 'There will never be an ATI/AMD OpenCL app for the following reasons'! But please not this "sitting between two chairs" any longer! Please tell me you're joking. I'm not trying to start an argument here, but I really hope that you - a VOLUNTEER - are not making demands of the GPUGRID scientists & staff. They have limited resources, and we as volunteers are here to support them, not the other way around. Look, if you've got some AMD cards lying around, I can appreciate you wanting to put them to work on this project. But IMO we should all remember our role as volunteers. The AMD app will get here when it gets here. Or not. Getting in a twist and griping because your expectations aren't being met is counter-productive. Maybe I've misinterpreted your post...if so, I apologize in advance. Cheers! No, SMTB1963, I am not joking, but I have not 'demanded' anything as well. I said 'please' as you see in the second phrase of your quoted text of mine. :) Yes, you are right, we are the volunteers, but we are also the volunteers! :) We support science and the scientists more or less personally with volunteering a lot of money for hardware and power. In some cases this munificence makes the science possible in the first place, and I think this is one of these cases. I do not see myself as a 'Megacruncher', if that is a part of my statement that should have been misunderstood. But I know a lot of guys in my team and elsewhere, that could be interested in unleashing a lot of power AMD-wise (and CUDA-wise) on this project. And it is my point of view that all volunteers deserve to be kept up to date on the progress of such undertakings on a regular basis by an official. With this kind of answer of GDF and others: We would like to get some alpha app for ati/amd out by the end of the year. However, we don't know if it will good enough to go in production. The update of the server has required a very large amount of work so far. gdf I am satisfied, because it contains all the official information I waited for. First, there is an app in alpha development status, second, it could (and perhaps will) be buggy, third, the reasons that hindered the progress... Thank you to all officials and I look forward to help (alpha- or beta-)testing the app and will continue waiting with fingers crossed. Please continue keeping us up to date whenever you can find the time! Cheers and sorry again, if my chose of words in English was misunderstanding, as I am German and not a native speaker! ____________

	There is an app, and it will be beta tested when the scientists are in the position to do so, and have the time. The scientists built, tested (as well as previous unusable apps) and reported what they observed in this thread. Server upgrades and site improvements are presently being tested/developed. These are required for the project as a whole, and to facilitate the introduction and maintenance of an AMD app. When these are finished and implemented the scientists can then begin work on preparing to release an AMD Beta app. I'm not in a position to give a definitive release date, and I cannot see how the researchers would be, until just before being ready. As for commitment to an AMD app, it's my understanding that the researchers have put off the release of a new NVidia app at least in part to help forward the release of an AMD app. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help

	Right, TomaszPawel, 'this calls for immediate discussion', this seems to be all that is happening on the ATI/AMD front... 'Nothing new in the east, west, north and south'?! I am getting frustrated with waiting; right now I have an AMD Radeon HD 6990 and an ATI Radeon HD 5970, the former quite new, the latter sort of newish, but both ready to jump train, as soon as there might even be a beta app and work for it! So you so to say waste the power of four high-end GPUs...

	We agree that it's worth testing, and would be a worthwhile project. As for performances, the speculation can end when we have Beta tasks :) If you meant 'Cayman was 20% faster clock-for-clock' then you could add that factor into the equation, for a more agreeable middle-ground ;) 24/18 * 900/725 * 1.2 = 1.98. - Almost forgot about Antilles, and all those mid range AMD cards with only single precision. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help

	Definitely worth it. For many GPU-Grid would be the first worthwhile project to run on AMDs :) The HD5850 has 18 shader clusters at 725 MHz. Cayman has at best 24 and OC'ed about 900 MHz. You could go higher with the clock (given enough voltage), but so could the HD5850. That works out to be a factor of 24/18 * 900/725 = 1.65. So.. I must confess I underestimated the difference a bit. Let's agree to meet in the middle, shall we? ;) MrS ____________ Scanning for our furry friends since Jan 2002

	Cayman may only be 20% faster than a 5850 per clock, but there are some monsters compared to a humble 5850. For example, you beast cuts through MW tasks in around a minute, while an HD5850 takes about three times as long. I'm not saying AMD's will be great, but some people might want to use their AMD GPU here. If an HD 5850 really is about 1/4 the speed of a GTX580, then your Cayman might be somewhere around 2/3rds the speed of a GTX580. Even if performance is poor compared to a GTX580, there are other considerations: People with existing AMD GPU's have expressed an interest in using them here. Their performance per Watt or per Euro/$/£ is not known for the app. Some ranges of cards might be more competitive than others; mid-range AMD GPU's would be competing against many CC2.1 cards, rather than CC2.0 GPU's. So, worth testing sometime I think. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help

	AMDs current VLIW architecture is much harder to utilize efficiently than nVidias scalar shaders. That's likely why they've got these problems at F@H and why they're not yet rocking GPU-Grid. Sure, software is also a very important piece of the puzzle.. and AMDs compiler has a harder job keeping these execution units fed. But it's not always possible to work around fundamently architecture limitation by software - so it's not only about software maturity and "trying hard enough". AMDs upcoming "Graphics Core Next" (GCN) will be the first departure from the VLIW since many years. It should be a lot easier to utilize. However, I doubt the same code path will run good on both, GCN and VLIW. That will lead to a very interesting, if not at times frustrating situation. BTW: actually there's not that much of a difference between Cypress (HD58x0) and Cayman (HD69x0) apart from switching from VLIW5 to VLIW4. At best Cayman is 20% faster per clock. That matters a lot if you're competitive, but is nothing if you've got a catch up an entire order of magnitude :p MrS ____________ Scanning for our furry friends since Jan 2002

	It's hard to compare performances between different projects, especially Boinc to non-Boinc. However I would still expect a high end AMD GPU (HD6900) to significantly outperform a high end CPU (i7-2600), which is not the case at folding. We know the performance is not great compared to high end GTX500 series GPU's by NVidia, but again we are comparing mature CUDA apps to a pre-Beta OpenCL/GL app. Basically a GPUGrid entry level NVidia card (say GT240 to GT430) would be on par with a mid-range AMD GPU (say HD5850 to HD5870). Obviously the high end 6000series should fair much better; perhaps approaching say a GTX470. I would expect the high end Southern Islands GPU's (7000 series), supposedly due out before the end of the year to at least match a GTX470. That said, Kepler would stretch the gap again, when released. Would be beta testing will come down to time/timing; some work presently under way has to come first. How long that takes depends on the problems that are encountered. Not sure if a new NVidia app will happen first (presently on hold until next 2012), perhaps just for Linux, what the situation is WRT publications, seminars..., and the researchers might want to finish off some work using older code before anything happens. Should a beta test run, be successful, and a live app be successfully used for a while, development might mean the gap here between AMD and NVidia apps would fall for GPUGrid, perhaps even with a mature OpenGL 4.2. However, such positive speculation should be made cautiously; a Beta could demonstrate unreliability, and require too much work from the researchers to get an AMD project off the ground. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help

	I am also interested by the future support for ATI / AMD, but I hope it will be stable and the performance will be a good level ? I am part of the beta-team on folding @ home and for this project the performance of ATI / AMD is not very good even if there are improvements.

	We are practically ready with the app alone. We have to test it on the context of boinc now. First thing to do is to update the server to a more recent version, then wait for problems. Our server software is quite old and there could be problems which would only appear in a couple of weeks. I don't want to test AMD with the old server as no opencl was there then. In the meanwhile we will do our tests locally on a private new server. An other thing to say that it will be windows only for the first several months. We have tested on one OS (XP32) and one card (H5850). So expect few issues. Hopefully, it all works and we can start submitting real workunits for amd. In such case they will be on a different app, not to affect the work on nvidia cards, but the porting of the code is complete, so they will be of the same usefulness of nvidia wus. gdf

If your English is not great, post in your preferred language as well; a bad English translation is unlikely to get a response, but if you also use your preferred language someone will probably be able to speak it or make a better translation. You can use Google Translate, to get a reasonable translation. Using simplified language helps.

	GDF said before that it's crashing a lot. I don't know anything else, though. BTW: I've got Milkyway@Home running on my HD6950. It was fine with the release data beta Cat 10.12, but with Cat 11.2 it keeps crashing in conjunction with Win7 and Firefox 4 or a modern Winamp skin. Going to install 11.3 now and hope things improve. MrS ____________ Scanning for our furry friends since Jan 2002

	Stanford just released their OpenCL client for ATi (OpenCL 1.1, so only Radeon HD5xxx and 6xxx cards, older cards are being abandoned by that project), based on their opensource toolkit OpenMM. They seems to be happy with SDK 2.3, and a lot more for the speed improvements in 2.4 (in beta/RC now, with the latest 11.3/11.4 drivers). What about you? Can I ask what are your real biggest problems deploying ATi OpenCL client? You keep saying that it's buggy and I could be fine with that, but could you just elaborate a little bit on that? It's my curiosity asking!

	It's now the middle of February and nothing? I really don't mean to be pushy, but there are several ATi users just waiting to contribute to this project. Even if it's buggy, there are several of us here that would help you guys out with testing and hopefully provide useful feedback. Like I've said before, something's better than nothing. Myself included, I am going to upgrade back to an nvidia GPU soon, but still would like to beta test an ATI app

	Given the expected ETA's of the next two APP SDK's and some knowledge of the researchers timetable, I don't expect another sustained attempt until around Aug. If the drivers are not stable for a range of cards then by the time you debug/find work arounds, the next APP SDK will be out, making your efforts worthless. ATI even changed the name from SDK to APP SDK. It's down to ATI to have a useable APP SDK from which to work from.

	I cant find a future AMD Accelerated Parallel Processing SDK (APP SDK) , but my guess is SDK2.4 will be released in mid of April: The last release dates have been in Dec 2009, Feb 2010, May 2010, Aug 2010, and Dec 2010. It looks like the release dates are spreading out; the gap has been 2months, 3months, 3months and 4months. So being optimistic my guess is about 4months from the 13th Dec 2010 release date – mid April 2011.

	GDF said that the problem was numerous bugs in the present SDK package. We know speed is not great but getting a working app is the main problem. Perhaps they will do better using Windows with the present SDK, but I am not holding up much hope. If not then we will have to wait for SDK 2.4, and testing will basically start over again.

	Yesterday Lunatics released their first ATI-OpenCL App for SETI (Multibeam). :-( ~25min/task @ HD6950 6.10 (ati 13ati) ~21min/task @ GTX460 6.08 (cuda) looks like ATI and OpenCL are not really best friends, but at least they run stable (I updated the ati and nVidia-drivers today).

	If one can accuse SK of being a fan then it would be a GPU-Grid fan ;) The projects currently working on ATIs are comparably simple. That's why it was possible (for a single person in case of MW and CC) to optimize them this good and to get a stable app. The more you have to rely on calling complex functions from ATIs libraries the more you depend on them fixing their stuff. Which is not exactly easy. NVidia invested a huge amount of money into this software and still GPU-Grid does find quite some bugs in their code / drivers. Anyway, the ATIs traditionally provide lot's of raw computation power per $ and good power efficiency. And in Cayman (HD69x0) this power became easier to use. So.. hopefully at some point it'll work. Don't put too much hope into OpenCL yet, though. It's not quite where people want to have it. And being able to run on anything doesn't mean one code path will be fast & efficient on anything..

	You have spent a lot of time crunching mathematical projects such as DNETC, PrimeGrid, and Collatz, but not so much for the more humanitarian projects. Do you put your Cypres to use at Folding@home? Perhaps you should have thought through your choice of GPU a bit better before purchasing it and limiting yourself to mathematical analyses. While OpenCL is a cross-device open language, each device still requires working drivers.

	@skgiven: I apologize for my misinterpretational words. I wrote it "it looks like..." not "there is ...". Of course I can´t help you, because my experiences in molecular modelling are more then 17 years ago and then these calculations were on an very early stage done on an 80286. And I´m not a programmer, only a lecturer and very interested in boinc and the projects. I want to spent my power and energy in "humanic" projects. My thoughts were that from 2,111,537 boinc users (boinc-stats today) some have the knowledge to help this project. Of course akosh (I think that is the right spelling) was no gravitational expert "only" an interest user of E@H, who improved the performance of the apps. Now his optimations are included in the standard code of E@H apps.

	It’s easier to write simple apps and if ATI doesn’t adequately support the creation of more complex apps then its better to wait for the next SDK than to continue to debug and report endless errors, knowing that they will not be fixed until the next SDK, if at all. I don’t know of another Boinc project that manipulates large molecules. Perhaps there will be better support for Vista x86 and Win7 x86. http://dnahome.cs.rpi.edu/dna/ This project is in an very early stage and I can not say for shure, that it is as complex as GPUGRID, I'm no scientist. And until now there is no GPU-app, but moderators say they plan to do that. Another thing: as far as I understood, OpenCL is a hardware independent programming language. Since GDF did some tests with an openCL app and it looks like he has an ready to go app (a lot of effort has been put it to get there with large structural changes), he could release that as an nVidia-app. This gives the possibility to test the app in the field und to compare speeds, at least again the cuda-app. This could also solve some problems with the apps for fermi only and non-fermi apps. MW did that; the openCL and the cuda-apps take exact the same time to complete (only a few seconds apart for a 17min task). Please do not misinterprete my words, I really don't want to bother anyone. Your efford to develop the project is appreciated. It's my interest for this project that leds me to encourage you to distribute an ATI-app, even if it is unstable. I will not post angry words.

	MW, Collatz and Einstein dont run molecular dynamic simulations, their apps are more simplistic and very different. Yes of course, you are right. But one word to MW/Collatz: both projects have Cuda and ATI apps. They are simpler for both types, nVidia AND Ati, but both apps are faster on ATI and use much less power also. So don't let the ATI-apps die!

	We have done our bit, it's just them that have to produce a working SDK. We have filed so many bug reports in the process. We will keep the possibility to run ATI,a lot of effort has been put it to get there with large structural changes. The last attempt we have planned to do is to see if Windows is more stable than Linux. All our tests were on Linux so far. ATI gpus are quite good, especially the latest generation. So hopefully we should be able to run on them. gdf

	Looks like a real fan-boy speaking... I expect you came to that conclusion by reading one post. Is ATI only a mathematical GPU??? You answered yourself, Akatosh: Einstein@Home ClusterPhysik(Gipsel): Milkyway/Collatz By the way: Why not using external support? there are excellent examples in the history of grid-computing Funds and expert ATI OpenCL programmers familiar with molecular dynamics don’t grow on trees. Might have been an excellent example if it came with a link, but I doubt it; MW, Collatz and Einstein dont run molecular dynamic simulations, their apps are more simplistic and very different.

I suggest you concentrate on CUDA for the foreseeable future; I know of several aspects to the present CUDA apps that could do with your attention (I spoke too soon, being addressed here). If an ATI app is not going to happen, put it to rest and let it be. Some projects have spent over a year trying to test and develop ATI apps only to find it is impossible/worthless.

	SDK2.3 is still unstable unfortunately. I am getting a bit tired of this level of software support from ATI. gdf could you please share the problems you found with the community? I think that many of us would like to read something about the problems you are finding and how you're tackling them. May I also say that maybe some problems rely on your side? I'm reading many positive comments about SDK 2.2 and 2.3... Surely a lot of work is still required for optimization, but an app should be working by now!

	There has been continuous speculation as to when ATI cards would be facilitated by this project. While another SDK has been released and the programmers might be working on this or at least planning to, it would be wise to accept that so far there have been lots of disappointments and false dawns. I don’t want to get anyone’s hope up on the ATI front because of this, but I also understand some of the hardware requirements might not be in place to support such an addition to the project. Also note that if ATI cards are supported at some stage, the initial phase of their introduction would be bumpy with lots of testing, problems and periods of inactivity. So don’t think someone can just flick a switch and suddenly GPUGrid will support ATI cards. Over the last year and a half I replaced my ATI cards with NVidia cards, to support this project. While I can’t see many people leaving the mature NVidia apps for infant ATI apps, I agree there is a lack of Biological and Medical GPU projects for ATI crunchers and respect that many would be happy to crunch here even at 30 to 50% the performance of an NVidia card. However, the problem is not just development; it is implementation, maintenance and support and these things require funding, equipment, space, time and staff. So while I look forward to having at least one ATI card in the future, it's likely to be at least a year before I fork out on one, and I do have a GTX260 and several GT240's that could be replaced should something come along.

	Boudicca, you must not install BOINC in "protected mode" in order to use GPUs. It's an option during installation which is active by default. Reinstall 6.10.58 (to the same paths, so you can keep all your configuration files and WUs), look for this option and deactivate it. Regarding the driver: just go to amd.com and get the latest from there. MrS ____________ Scanning for our furry friends since Jan 2002

	Boudicca, You may want to determine which model of HD 5570 card that is, find it on this list and click on that model name , then click on Details on the resulting page to get a page including more accurate information about what rating of power supply is needed. For example, if you scroll down in the details for the first model on the list, you'll see that it needs at least a 400 watt power supply (possibly less if the rest of the computer is on a separate power supply). http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=HD+5570&x=11&y=25

	Boudicca, ATI cards do not presently work on this project (GPUGrid), hence the message, "No usable GPU's found". Try Folding@home if you want to run a molecular folding project; they also do useful science.

Is that the only graphic card in your PC or is there also an on-board card? AMD (unlike nVidia) needs a monitor plugged in (or a dummy-plug) to be detected by BOINC.

	excuse me if this has already been answered. Or if I should know better. But, i need a bit of help here. Just installed a Radeon ATI HD 5570 GPU on my husband's computer (Intel Pentium dual cpu E2160). Increased the Windows experience rating from 3.8 to 5.9 immediately. Boinc says for ATI 5500 series GPU's you need to have driver V8.12. Windows vista went on the web and found ATI HD 5500 driver V8.791. So, I installed it. Next, when I installed the driver that came with the graphic card, it went to V8.77. Whatever :-\| When that updated itself, it went to driver V8.791, then again to V8.8 when I installed what they call, "Catalyst Control". HOWEVER - - When starting up Boinc V6.10.58, it gives a message "No usable GPU's found". I like the 5570. It was cheap ($69.99), fits our Dell 530s SLIM profile case, however occupying the only single PCI X16 slot on the MB (the other three are PCI1, PCI2, and PCIX). It is passive (no fan - no noise)with massive heat fins on both sides of the card (and over the top - still fitting the SLIM profile case), and has a nifty utility for panning across multiple displays http://ati.amd.com The stock Dell 530s has only a 250 watt PSU, but I have been assured (on another forum) that it will work OK. So far so good! Two HIS Radeon ATI HD 5570's can be installed on a MB with two PCI X16 slots if you have them; but for that a 400 Watt PSU is recommended by ATI. Then, it lets you run, what they call, "Crossfire Mode" which, I suppose really zooms it up. Did I say, - - When starting up Boinc V6.10.58, it gives a message "No usable GPU's found". Am I barking up the wrong tree?

	Boinc Projects are going to want to facilitate Open-CL: The forthcoming Sandy Bridge contains 6 or 12 integrated Execution Units (an on-die GPU). These 32nm processors will replace the mainstream LGA 1155 i7’s, i5’s and i3’s. While they are unlikely to be useful to GPUGrid for GPU tasks, other projects such as Einstein might be able to utilize them to good effect, and I expect some big projects will use Open-CL in order to employ these CPU’s more fully. Intel have doubled the SSE data path and introduced Advanced Vector eXtensions (AVX), an advanced SSE. Open-CL is knocking at the door.

	From Extra Terrestrial Apes: The feature needs OpenCL, though --- Looks like time to ask the BOINC to provide one of two possible new features, whichever one they'd prefer: 1. Add an OpenCL interface to BOINC. 2. Allow workunits to tell BOINC to reserve a GPU for them, then turn loose of that GPU in all other ways until the workunit finishes. The application program would then have to contain all the code needed for interfacing to that GPU, but at least that would be better than not being able to use it at all in the desired fashion. Another idea to consider: Provide workunits with two independent parts taking about as much time each. On Fermi processors, use the new feature to run one a while, then while the other one is running, do the CPU interfacing for the first one. On older processors, run one after the other instead.

	I especially like the new feature "asynchronous dispatch". It lets different apps be executed on the GPU at the same time. Fermi only allows different kernels from the same app. This could help with GPU utilisation, if the problem is using more Multiprocessors, or if the GPU is not used all the time. And it could make crunching GPUs more responsive, which is always welcome. Might even help with the CPU support / synchronization issues we're seeing at GPU-Grid now. By that I mean the CPU is not acting fast enough to keep the GPU busy - which would be much easier if the GPU was working on 2 WUs concurrently and with half a step phase difference. That way there'd be a rather large buffer or time window until the next CPU support would be required. WOW, that feature alone is peaking my interest in GPU coding. I imagine this a result of AMD's Fusion direction. More reading to do... M.

	Looks like 10.2 turned up yesterday (13th Dec). The researchers may still want to wait until after the holiday period before beginning internal testing, and there is no guarantee they will be successful any time soon. They have to get it to work first and then optimize it to a reasonable level. I see little point in rushing an application into test release only to disappoint lots of ATI users, especially at this time of year. If and when they are ready to go to Beta they will make the very welcome announcement.

	ATI's roadmap suggests they will release SDK2.3 this month. Even if ATI are on target, I don't think the researchers will want to spend their holiday period debugging test apps. My guess is that it will be next year before any Beta's are released.

	Sorry, I have no idea what you're talking about. I don't know who Jack is. I just know you said you were 100% sure it worked and then said it didn't. So I assumed you actually saw the machine with the HD2600 running such a WU. Which would actually be quite possible, since openCL can in principle run on anything as long as there's a driver mediating between the hardware and openCL. The first devices on which openCL was run were CPUs. That's why I could imagine you saw that WU running, but openCL had determined the CPU as the only appropriate computing device and was using that one instead of the HD2600.

If you go here, https://simtk.org/project/xml/downloads.xml?group_id=161 it will redirect to amd gpu page, which has support for opencl only gor 4xxx and up. On the 2600 card, is it going to take around 20h for the WU described? I know, i'm not the developer, if he made it compatible with older cards, then so be it, progress.... you should be congratulating us instead of criticizing it... ati may only support 4300 and up but we know the true reason for that.... ( They want to MAKE MONEY ON THE CARDS!!!!!) but the truth it is opencl is compatible with the 2600 xt, my card running it proves it... We know that our research, will take sometime... that's why we've been wanting to go to gpu apps as they are much faster than the single cpu... and well have cuda to go along with ati.

	I dont know of any reason to require double precision for here, so only single precision would be required. Agreed. Otherwise almost none of the nVidias would work here, or would have trouble keeping up with CPUs :p MrS ____________ Scanning for our furry friends since Jan 2002

	An idea on how to produce a GPUGRID version for the AMD/ATI HD4nnn family, once you get suitable software support: See if you can divide the tasks between upper level processors which can reach all of the graphics card's memory, and lower level processors which can't. Tell the lower level processors to do most of the calculations, but send their requests for access to memory they can't reach to the upper level processors. Note - I'm NOT familiar enough with the AMD/ATI GPU architectures to tell if this is possible, or even what you've already tried.

	For those interested in protein research: Poem@Home is starting testing of GPU versions of their program, for both Nvidia and ATI cards. Name is POEM++; current version is 0.01. Poem@Home currently only has POEM++ CPU clients out. Once they are convinced that these are stable they will start rolling out the GPU clients. Current estimate is that this will happen in a month or so.

	From skgiven: I think Folding just does protein folding, so it is different to this project; GPUGrid is unique in that it looks at super-structures (complexes of large molecules, such as lipid bylayer spanning pore proteins). Folding is more akin to Foldit in its research. For those interested in protein research: Poem@Home is starting testing of GPU versions of their program, for both Nvidia and ATI cards. Name is POEM++; current version is 0.01.

	ATI 2.2 fixes most serious bugs and we will probably put out a test application for ATI. The performance is still poor for several reasons. ATI on one side and us on the other, will work to make it faster.

	Perhaps the scientists will have another look at ATI cards in September or October, but they have a lot to do; optimize the GTX460, and forthcoming GTX475, try to get working apps for the GTS450, GTS445 and GTS440 (due out on the 12th), as well as the GF108 cards, also due out soon. Last I heard they were perhaps about 50% of where they wanted to be WRT performance, but there were still bugs in the ATI code, that would require fixing before they could progress. If ATI have fixed their compiler and libraries then I would expect GPUGrid would be keen to restart work on an ATI application quite soon after the summer holidays.

A 57x0 app may follow, probably, if all goes well and they prove to be fast enough. Lower 5xxx series cards will definitely be too slow to be useful. And the 4xxx is right out. MJH

	@MJH: may I ask why? To keep things as simple as possible initially or is there any important technical difference for GPU-Grid between e.g. HD58x0 and HD57x0? @Werkstatt: I'd put it this way: imagine some guy compiling a "hello world" program in C++. Now there's another guy who's trying to build the perfect operating system. He may also be using C++, but can not get it quite as bug free and stable within a finite development time. It's not that the other projects would be trivial (), but they're using different functions, libraries and API calls. Apart from the fact that they're using a different API these differences in the code alone would be enough so that you can not simply say "Just do the same stuff the others did and it should work". Well, it probably would work, but it wouldn't be doing any GPU-Grid science ;) Are these apps producing wrong results? That's not the point (and is probably not the case). For GPU-Grid the problem is that using the current SDK the app is not stable. And if I understand correctly the problems have been traced down to API calls (functionality provided by ATI), so it's up to them to fix it. MrS () the code of CC and MW is not very complex, but certainly not trivial either ____________ Scanning for our furry friends since Jan 2002

	CAL is the old programming model. It is deprecated.

I understand, that the 260-192 has (build-in)troubles, but all ATI-cards work without any problem in all related projects. Are these apps producing wrong results? I'm not so happy to cruch for the search for numbers (collatz) and I'm waiting for a more intresting project (that may help more people than a handful of math freaks), that use my gpu's. Doesn't it make sense to try to connect the programmers of these project, just to exchange experience? They should have the same problems and they seem to have a solution. Well, I'm not in the process of developing these apps, so my thoughts may be completely wrong. If so, then please forget my question. Regards, Alexander

	We are waiting for ATI to fix their compiler and libraries. There is no much we can do. Some new tests are in progress these days. Looking at the progress we are moving, I would expect to be in a stable, production situation with a OPENCL ATI application for GPUGRID before the end of the year. Of course beta work will start several months before. Maybe even just after the summer. All depends on them. If they do a good job, I would expect an ATI 5870 to be within a factor 2 slower or faster than a GTX480. I know that the two extremes are quite different, but remember that few months ago, an ATI 5850 was 10 times slower than a GTX275 with ACEMD... gdf

	In so much as PoorBoy is loyal to Boinc, others are loyal to Folding. Perhaps if Folding and Boinc colaborated in terms of recognition (points/tasks/achievements) it would be more favourable, but Folding is a very big project, with hundreds of thousands of present crunchers. They dont need you as much as GPUGrid does. I may be wrong but it seem to me at one time Folding & BOINC tried to get together but never could Iron out the Details. From what I think I remember Folding wanted everything to much their way and the Deal never went thru ... Like I said I think I remember something like that taking place in the past ... ____________ STE\/E

	It's a bit off topic, but ATI for SETI? I didn't hear about that heard yet. How's performance? MrS Still in Beta and it is for the AP tasks only as far as I have been able to find out. Again, the preliminary reports are that it is somewhat like the EaH application in the it uses more CPU than most would like though that is supposedly falling as they have worked the code. The main coders are on Lunatics and the beta is not a full open beta yet ... The hybrid version (for 2xxx and up) yes, still using too much CPU, like the EaH. The OpenCL+Brook+ (for 4xxx and up) is using 98% GPU + ~5% CPU.

	I agree with the wrapper for folding, the one for dnetc looks good. The fah client is not so user friendly in comparison with boinc. I stopped folding a month ago due to the poor optimization of the ati client, and also the reluctance to give feedback to the 'new client'. I'm using my ati cards for seti and collatz (the low-level ones).

	Would be nice if F@H introduced a BOINC wrapper, like e.g. yoyo@home. But their entire infrastructure is probably not very compatible with BOINC and they looked into it some time ago - and found it not be stable enough (or whatever other reason).

	I think Folding@home is a good project, and I have run a few hundred tasks there. Their cutoff times are longer, so people that struggle to finish here, or use older cards might want to try folding. The GPU utilisation tends to be higher, so watch out for the heat. My general opinion is that if the card cant work here it's not worth having, so I get rid of it, or just dont use it - it's down to project preferences, and I'm not interested in some sciences. I think Folding just does protein folding, so it is different to this project; GPUGrid is unique in that it looks at super-structures (complexes of large molecules, such as lipid bylayer spanning pore proteins). Folding is more akin to Foldit in its research. In so much as PoorBoy is loyal to Boinc, others are loyal to Folding. Perhaps if Folding and Boinc colaborated in terms of recognition (points/tasks/achievements) it would be more favourable, but Folding is a very big project, with hundreds of thousands of present crunchers. They dont need you as much as GPUGrid does.

	Reason enough for sure. The reason I asked is that you seemed to have a particular animus towards Folding as indicated by your statement: they'll sit Idle before I run Folding@home ... Folding seems like a worthwhile project to me so I was wondering if you had a bad experience or something? No, I've never had any dealings with Folding & from reading about it I'm sure it's a worthwhile project. But BOINC was what got me started (SETI Classic) & BOINC is what I will stay with. If Folding ever came under the BOINC Umbrella I would run it but until it does I won't a long as there are BOINC Projects around to run ... ____________ STE\/E

	just out of curiosity have you tested your openCL code on a CPU yet? AMD's opencl cpu compiler should be more mature and less buggy than their gpu compiler. it would also be a nice performance reference.

	I second ETAs comment. I also became a recent convert, after 15 years with NVidia ever since NVidia started on the consumer end of things. The ATI performance on the non BOINC tasks I do has been amazing, it far outweighs expectation let alone hard comparative performance figures. On the BOINC ATI Projects I am now running, it flys .... Kicking myself I didnt make the move earlier end of last year, but we all live and learn I guess - I had let the last 15 years colour my judgement. I certainly add my lowly voice to the chorus of thanks to AMD for the assist, lets hope it remains over time, and is substantive not transient. Regards Zy

	Great news, indeed! If you haven't done already, tell AMD that their help and hardware are greatly appreaciated in the world of BOINC :) MrS Even better point out that the more projects that run ATI applications that work decently, the more cards they will sell to this small, but intense market ... I know I am solidly in the ATI camp and am down to my last couple of Nvidia cards as we type/read ... and if they stay ahead of Nvidia will stay ATI for some time ... I can see that some of the bigger ranchers have 20-30 systems and they tend to stick with the same cards if they can find one that works well ... We are not a big as the gamers segment (yet), but 300,000 users world wide is not a trivial market to ignore either ...

	The SDK2.1 is better but still has several bugs in parts which are required to run the code reliably. We must wait for the next release.

	Ugh, I would expect based on other projects that those numbers would be more like reversed ... :( Just don't forget that ATIs 5-wide execution units give you more raw compute horse power per transistor, but are also harder to use efficiently.

	One ATI HD5850 and a HD5670. The current speed of a HD5850 on ACEMD is twice as slow as a GTX275 (one month ago was ten times). There is still scope for improvement. The code is not stable yet, maybe with 2.1. gdf Ugh, I would expect based on other projects that those numbers would be more like reversed ... :( Still, as you note, still room for improvement... Looking forward to being able to try it ... I seem to be down to only one card on GPU Grid in that I put the GTX295 card back into rotation but all the tasks seem to be failing ... :( So, down to only one GTX280 card ... which on DNETC, Collatz and MW is considerably slower than the HD5870s which are my current backbone...
