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" | |

It's to sponsor their project, not personal gain. | |

GDF, why don't you give away resources of people, who came here to crunch for science, to render commercial graphics? it will bring you even more money, and stable payouts | |

HI Steve. We will add that this is using BOINC. 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 | |

For me the bitcoin network is an impressive idea. Read about it: 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? ____________ STE\/E | |

It's a nice idea, but I'd rather donate my GPU resources in a more "scientific" way through GPUGRID. | |

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. | |

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. | |

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. | |

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? | |

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. 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. | |

I'm about to look up the HD 7970 and check if it fits my rather tight power limit requirements, or if I need to wait for a later board in that series that does. | |

if you like to "fold" some aminoacids/proteins with your GPU, you now can try POEM@Home and their new open CL app. I'm still waiting for the windows version and the gpu version of hcc over at wcg. The system requirements on this project are too high. I'm out. | |

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. | |

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. | |

We don't know yet, but we will start testing on GCN cards and initially support those. I am expecting enough problems already with a single compiler generation. If this is the best answer after 2 years of waiting, to support an architecture that it's not even out yet, then ... good luck with all that | |

HI, In an older post you said that the amd app should support OpenCL 1.0, meaning 4xxx series and up. Are you trying to say that the 2 previous architectures will be abandoned? | |

For people outside research it's sometimes difficult to imagine how it works... [beamed Kirk & Scotty out of quote] ...there's always something unexpected crossing your way. The question is just how severe that is and how much effort it takes to get around it. Personally I wouldn't dare committing to a release date for a highly experimental piece of software. Well, one could release a half baked alpha in time.. but that wouldn't please people either. Hmmm, This sounds a lot like software development at work. Oh, wait, this IS software development!

Seems like things have calmed down again, but I'll add some more cents anyway: My Genealogy software did exactly that, they gave a hoped for release date and then caught holy he!! for missing it. They came on and gave the reasons for the delay and it did not help!! They now say it will be relased when it is ready and not before, they still catch some flak but not nearly as much!! | |

The question is just how severe that is and how much effort it takes to get around it. Personally I wouldn't dare committing to a release date for a highly experimental piece of software. Well, one could release a half baked alpha in time.. but that wouldn't please people either. And people tend to be impatient and tend to hear what they want to hear. So "we hope to get an alpha out by x" quickly turns into "Woow, there'll be an app by x!". Which is quite different.. MrS ____________ Scanning for our furry friends since Jan 2002 | |

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! 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. 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! ____________ | |

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! | |

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. | |

No, that 20% comes from the fact that Cayman has 24 shader clusters compared 20 in a full Cypress. On the HD5850 2 of them are deactivated. That's where the first factor 24/18 comes from ;) | |

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. | |

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". | |

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. | |

The new amd app will require OpenCL 1.1 and double precision cards? The nVidia code doesn't require dp, so there's no reason why the ATI code would. Can't tell you the OpenCL version, though. MrS ____________ Scanning for our furry friends since Jan 2002 | |

We have a more or less advanced stage application for AMD. Performance could be better, but at least it seems to run stably in a local machine. We might have a release of an alpha-app in the next couple of months. | |

On ATI development, I don't hold up much hope for the immediate future, The quality of any OpenCL implementation is simply poor so far. At every new version one bug is fixed and two new appear. For us, it was just a big loss of time, but we will be here for AMD when they are ready. On language, My advice is to post in English if you can. 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. I have no objections to a few friendly words in any language, but if anyone is going to ramble on use the Personal Messaging facility. If you see a post in a language you don't understand, it's probably small talk, otherwise they would probably have posted in English. | |

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). | |

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. | |

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. | |

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. 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! | |

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 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’m not in the least surprised to hear that ATI support is insufficient, and I seriously doubt the merits of perusing an ATI application suitable to the complexities of this projects research.

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. 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. | |

then again to V8.8 when I installed what they call, "Catalyst Control". 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. | |

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. | |

yes, i'm sure it's running on the 2600 xt... it's my computer... 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. | |

If you set the environment variable SWAN_SYNC=0, in most tasks the use is around 97% in GTX480 in GPUGRID. A command line parameter? I'm not very skilled in programming. More hardware.

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 | |

Sorry for asking again, but are you going to reguire single or double precision for ATI client? | |

An idea on how to produce a GPUGRID version for the AMD/ATI HD4nnn family, once you get suitable software support: | |

Yes, the level of stability is still not sufficient for the use in GPUGRID. | |

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. | |

From Paladin*: PS: As a side note Subscribing to a Thread is Pointless for me as I never receive a Notice by E-Mail even though I have my Preferences set to do so ... ??? Some of the ISPs in Germany are using a rather obsolete list of which other ISPs to block email access to - for example, it includes mine, whose outsourced newsgroups server USED to be a common posting point for newsgroups spam. In the years since then, it brought the newsgroups server in house with a newsgroups person more active in controlling spam, then was acquired by another ISP and dropped newsgroups entirely. You may want to check if whatever ISP you have your email account on is on one of those obsolete lists. | |

Performance of a top ati card however is 3 times slower than a fermi at the moment but at least it runs. Yay! I'll take it, back to basics. First make something work, then fine tune the process. At any rate my 5870 will accept beta work units, if/when some are issued. It's been crunching a long time now, and curious about GPUgrid. M. | |

sdk 2.2 out... | |

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. Most likely, SDK 2.3 could be a better release performance wise, now that bugs are under controls. I have a 5870..do you still plan on doing a beta release the end of summer or is it sooner? | |

ATI 2.2 fixes most serious bugs and we will probably put out a test application for ATI. I've set my mainsys (with two ATI-cards) to accept GPUGRID wu's. If something more to do is required, I expect instructions somwhere. Regards, Alexander | |

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. | |

Does this mean that the new SDK is available and testing of the ATI-apps is going on? | |

i guess you could say that. local data share on rv770 was too restricted to meet opencl requirements. | |

GPU-Grid doesn't need DP and this is hopefully not going to change anytime soon. At least one important difference between the 4000 and 5000 series is flexibility in memory management, if I understood correctly. | |

Why? 5xxx series has OpenCL 1.1 support. If you can get the 57xx series to work, at least you aren't going for DP :) . | |

Why? The design of the R700 processor used in the 4xxx series cards prevents the complete implementation of some features of OpenCL that are of critical importance for our application. (It's yesterday's technology, sorry!) MJH | |

The 58x0 is what we work with here. 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? 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.

I dont think double precision is on the cards (it is not needed now), but that does not mean that a 5770 would not work. If ATI GPUs do eventually work here, that card should be a good one. | |

If there will ever be an ATi support for GPUGrid, will double precision be required for the card? In other words, will I be able to run GPUGrid on 5770s? | |

CAL is the old programming model. It is deprecated. If you have an old application it makes sense to use it still, for a new one, it's better to wait for OpenCL. Hi, | |
