Of course not! They just installed new hardware and they don't want to get it scratched and dirty!!

I've been taskless for about 4 days now. I purchased a Nvidia GTX 1055 (crippled GTX 1060 w/ 3GB) that replaced my blazing fast 48 cuda core Nvidia GT 520. Itching to get crunching on GPUGRID using the new gear.

Yeah, the server still says there are no new tasks available & over 2K in progress...

I purchased a Nvidia GTX 1055 (crippled GTX 1060 w/ 3GB) that replaced my blazing fast 48 cuda core Nvidia GT 520.

Perhaps they should have called it a GTX1055 or stuck with the GTX1060 and called the GTX1060-6GB a GTX1065 (AKA 465), but they called it a GTX1060-3GB, and they get to name their babies! Also, AMD had a Phenom II 1055T 6-core CPU, released ~6years ago, and NV have a GTX 1050Ti. My guess is NV didn't want to call one a GTX1060 and the other a GTX1060Ti because they have the 1060Ti earmarked for their 14nm mid-high end refresh next year, along with the inevitable GTX1080Ti... Maybe we will also see a suffix or something subtle indicating node refinement/GDDR RAM variations for the entry level variants too. NV do like to express themselves through nomenclature.

I have a couple 1060 3GB cards and posted the times for the ADRIA_2OV5_AMBER_OPEN2 WUs over here (also the 1050Ti):

https://www.gpugrid.net/forum_thread.php?id=4448

Maybe someone with a 1060 6GB could post a comparison time (also 1050, 1070 and 1080)?

FWIW the Phenom II X6 models were: 1035T, 1045T, 1055T, 1075T, 1090T and 1100T.

I'm keeping the 1060 occupied on milkyway@home for the time being. With 5 concurrent tasks it averages 3 minutes a piece. Mechanical hard drive thrashed and thrashed with 10+ tasks but I got her up to 19 tasks before the system became totally unresponsive. I imagine the workstation simply ran out of RAM leaving it up to the pagefile.sys and readyboost which could't juggle/sort out all the data. The GTX1060-3GB never maxed out its memory during the entire ordeal and in fact it was twiddling its thumbs and sat near idle at times (after completing a task before starting another) waiting for workstation to get over itself.

Quite impressed with the GTX1060-3GB! With 100% utilization running 5 MW@H tasks it runs cool (currently a cozy 102f/39c with fan speed at 90%, sips power, and is easy on the wallet. - - Still would love to witness a 1080 in action though!

39C is a little unnecessary, I think you could lower the fan speed and keep the gpu at 50C and it would last just as long as 40C. As long as you're not over 70C it's going to last a long time.

-Off Topic-
70C is roughly where systems remain stable. If the GPU is 70C usually everyting else is less and probably not going to fail. However, everything else in the system is unlikely to be certified and guaranteed to operate at 70C. Many components deteriorate noticeably at or just above 50C, including GPU components. That's why we have system, CPU and GPU fans. Just about the last thing that's going to fail is a wafer of silicon (CPU or GPU) - basically it's purified carved rock. The stone age isn't over!

10-4, Will do (50C)Great info.

I throttled down the fan and observed the following (as a mini-experiment):

@ 51C/124F the GTX 1060 throttled itself down from 1936MHz to 1923 (-13MHz),
@ 61C/142F lowered to 1911 (-12MHz),
@ 67C/153F lowered to 1898 (-13MHz),
@ 71C/160F lowered to 1885 (-13MHz).

At 71C I put the fan back up to full speed until it cooled it down to 50C.

@ 50C/122F fan speed is 40%/1040rpm and the gpu is running its original 1936MHz. So you helped me save 50%/1300rpm in fan usage.

Thanks again for the info!

Salve agli esperti,
non riesco a scaricare unità da elaborare... può essere che il mio account è bloccato?
L'ultima unità che ho visto risale ad un paio di anni fa.
Da allora niente. Tutti gli altri progetti lavorano tranquillamente. Solo GPUGRID no mi da niente.
Chi mi aiuta a capire cosa è successo?
Grazie

Do not install BOINC as a service (protected mode).
You need at least 8GB free space on the drive BOINC is installed.
If it does not help, please restart your BOINC manager, and post the first ~40 lines from the event log of your BOINC manager.

Non installare BOINC come servizio (modalità protetta).
Hai bisogno di almeno 8 GB di spazio libero sul disco è installato BOINC.
Se non risolve il problema, riavviare il gestore di BOINC, e dopo i primi ~40 righe dal registro eventi del vostro gestore di BOINC.

You've restricted in your profile (in GPUGrid settings) that you crunch only BETA (test) applications, and there's no such work at the moment.
You should select long runs and short runs to receive work.

Me to. I had one that had run 46,000 seconds and cancelled by server. Wonder if we will get an explanation of why thousand of WU's have been withdrawn and running WU's cancelled.

in this minute, the project status page shows 290 BNBS WUs left for download, no other WUs available (at this time). These 290 WUs will be used up within the next few hours.
I am wondering if new ones will be made available shortly.

BNBS2 simulations are chained (i.e. when one completes it sends the next step of the simulation) so I don't expect to run out yet. Next week...maybe?...hopefully :D? You are totally wrecking it though, I can barely keep up with retreiving and processing them, haha. 3600 simulations running in parallel is pretty nuts.

You have to remember most people cache WU's so apart from those crunchers that actually run 2 at a time on a single GPU you don't have 3600 running.

Then there are those who will hold on to WU's for 5 days before they are resent. Not a problem while you still have enough to send but becomes a slow down when you haven't and are waiting for the last ones to return.

I have one such WU here which is still at the first part of the 5 part chain http://www.gpugrid.net/workunit.php?wuid=12275674

It looks like it's over for now due to there only being a single project on the list. I wouldn't be surprised if there are new ones coming out soon.

Is it usual for gpugrid to do stuff like this? In phases as in lots of work, no work, lots of work, no work, etc. I am not sure because I haven't been around too much. Maybe someone can tell me if this is normal or not? I'd appreciate it.

It looks like it's over for now due to there only being a single project on the list. I wouldn't be surprised if there are new ones coming out soon.

Is it usual for gpugrid to do stuff like this? In phases as in lots of work, no work, lots of work, no work, etc. I am not sure because I haven't been around too much. Maybe someone can tell me if this is normal or not? I'd appreciate it.


Ok scratch that. I just got a task for my system. Try to leave yours on and you'll get one like I did.

Yes.

In phases as in lots of work, no work, lots of work, no work, etc.
Even though the server status shows 0~3 unsent workunits there is work until the number of workunits in progress is higher than the number of the active hosts (2000~2500) as new workunits generated from a finished workunit (but it's instantly grabbed by some hungry host, hence there is 0 unsent in these periods).

Maybe someone can tell me if this is normal or not? I'd appreciate it.
To understand this a litte deeper, you should understand the naming architecture of the workunits. For example:
ARG59ALA_S14F21_C2-SDOERR_BNBS2-0-4-RND9058_2
The main parts of the name is separated by dashes ("-"), let's split this name by them:
1. The name (ID) of the molecules involved
2. The scientist's name, and the batch name
3. The actual number of this workunit in the chain (starts at 0)
4. The final number in the chain
5. The random seed number for the given chain, and the actual number of resends.
Since the chain starts at 0, the number of workunits in the chain is 1 more than the number in position 4. The last workunit in the chain has the same numbers in position 3 and 4.

Ok scratch that. I just got a task for my system. Try to leave yours on and you'll get one like I did.
We'll receive new workunits in a descending probability while the number of unsent is at 0 until the number in position 3 reaches the number in position 4, after that we'll receive workunits only when they timed out (sitting in the queue on slow, or overwhelmed, or inactive hosts).

So are all the important WUs like 0-2 in the chain assigned to the fast cards and the last one assigned to the slower cards? That would make sense as for whatever reason you can only run them in a serial chain rather than all parallel.

No, WU's are assigned randomly.

Each WU 0-4 has to be completed because 1-4 is generated from its result etc.

Zoltan, just for me to know: where can one see the number of active hosts?
I would have thought that this is the figure shown in the upper right hand corner of the project status page (i.e. approx. 5600 right now) - or am I mixing up something?

We can't have 5600 active hosts while there's only 3300 workunits are in progress, right? As a host can have only 2 workunits per GPU, and there are negligible number of hosts with multiple GPUs, the real number of the active hosts is about the half of the number of workunits in progress. There are 5600 hosts with recent credit. Now what does "recent" mean is unclear, perhaps it is the past 30 days, but I wouldn't call a host active if it's crunching only a few workunits in a month.

Thank you for explaining to me.

I noticed lately that the tasks are quite demanding lately on my GPU and I'm starting to get very close to missing the 24 hour mark. Is it time to upgrade my GPU? Which should I buy if I upgrade?

I'd like to know from the scientists too if I should get an upgrade, though. I don't want to buy a new GPU and come back later to see that my gtx 960 works just fine again under 24 hours (meaning these long demanding tasks are gone)

I probably won't be getting a GPU upgrade until I get myself my first part-time job after High School while I'm in college, so I can have a nice steady income. I like to look forward in the future purchases though to see what I want and set a goal.

Basically, I'm willing to upgrade if I should, but do not have a budget in mind at this time.

I think the long demanding tasks are almost gone now. So if you are just concerned about the 24 hour limit, I would keep the GTX 960 for now.

I second that. The gtx 960 is a good mid-range card and energy efficient (Maxwell). It is somewhat comparable to the new 1050ti in terms of crunching speed. So if at all, you need to upgrade to the gtx 1060 to have a noticeable speed improvement. Price is from 200 USD (for the 3G model) and up. But for the moment, if you miss the 24h deadline just narrowly, you may want to overclock your 960 a little.

You seem to have gotten 2 tasks right now. To avoid the waiting in these cases, I'd change your settings to "store at least 0.1 days of work" instead of having it set to 0. I just changed mine myself.

If that doesn't work, try 0.2 and keep going 0.1 higher to see which is good (until the servers offer lots of projects of course)

You definitely need backup projects with this project :) You just need to set the priority for GPUGrid to something ridiculous, I set mine to 10000 and everything else to 1

Or ... leave GPUGrid at 100, and set backup projects to the "backup resource share" value, of 0, which literally means "Only use this project when work cannot be retrieved from other projects and I need work now ... and only get enough tasks to satisfy my idle resources."

0 Resource Share, is very useful.

Thanks. Just for my understanding, where does this recurrent lack of tasks come from? Not enough molecules to analyze .. or not enough disk space on the server?

Most likely the scientists have to design the simulation which takes time and once completed they need to analyze the results and create and publish papers which summarize what they've learned. This is not a fast process so I would be more lenient towards expecting work at all times.

I'll have to keep that trick in mind. For now I'll do the resource share 1 for the backup since I have my main projects set at 1000.

Hm yes. It takes a while to come up with new meaningful projects or collaborations. We try not to send out simulations without a purpose. Also the analysis of the simulations takes much longer than the actual simulations. I can work on a dataset for a year (or multiple years in some cases) that was simulated in a month.

We sent out some adaptives (I work with ADRIA on a project) but I am discussing now with our collaborators if we should send out some more BNBS2 workunits.

Also the adaptives I send out now with Adria are some small tests which will lead to probably a pretty large project with lots of simulations. We do it step by step to find first which is the best method before we go crazy on the different proteins and thousands of simulations.

Theoretically I am sure there could be other groups/people wanting to simulate on GPUGRID instead of us having it idle, it is however quite complicated to organize collaborations, simulation priorities etc.

One more question, Stefan, if I may. Can your students possibly be involved in this kind of distributed computing? Maybe in the course of a laboratory tutorial, making their own simulations and evaluations on simple proteins, using spare power of GPUGRID. There are quite a few benefits from that approach,

    - you could feed the (frequently empty) short run queue.
    - you may save work time by outsourcing some minor problems to students
    - you may benefit from creative thinking of students
    - future researchers can familiarize with this kind of simulation and become group members occasionally



and eventually even distinguish between long runs, short runs and short "student" runs so that crunchers may choose between purely scientific and educational application. And in case the interface to GPUGRID is not yet open to students, that provides an opportunity for a diploma thesis.

Right! On the other hand, how should they learn it otherwise if not by trial and error? If we generate some aha reactions in young minds, I don't consider that as wasted entirely.

However we only teach one trimester per year so it would be a pretty short thing of ~3 weeks per year.


Well, 3 weeks are 3 weeks... and maybe one or two gifted students want to learn more (and contribute something really valuable) in the course of a diploma thesis because the lab tutorial made them curious.

What you could also try is making one dedicated workplace in the lab with (limited) GPUGRID access generally available to students. There, they could upload their own simulations in their free time and feed the "educational" queue. And I am pretty sure, there will be quite a few people using it. Isn't it awesome to know that thousands of volunteers provide their computing power just to solve your riddle? How cool is that? :-))

As an incentive, you could award the most promising results once a year by a prize of symbolic nature. Just a deed, mentioning on the institute homepage and maybe a free movie ticket. Well, that was at least something in my own studenthood long time ago. ;-)

Good natured as that sounds, I don't think competition belongs in research. This behavior leads to not posting something that went wrong so others can learn about it, and not posting a potential failure. Only the success ever gets published, and that's only half or less of the story.

Dont take a too narrow a view of it. From my own experience as a student (Techn. University Vienna) I think there can be many positive effects, students will likely team up to work on a particular Problem anyway. And they will certainly share information and have discussions about multiple approaches. I think that no one will do secret mongering because of just a symbolic prize.

And hey, competition has always been part of scientific research. There are scholarships and fellowships, grants and the race for honor and the best published work. That is the custom.

Well... that was just a minor detail of my proposal. Forget about the prize if you think it has a negative impact. Stefan, his colleagues and their professor have the best judgement anyway what could work at their department.

Oh we do make the students simulate :) The last years they simulated on some local machines we provided them with. Just not with enough computational power to make any real discoveries.

As bad as it sounds, from my personal experience the students of the Masters program are either too stressed out from too many classes or just not interested enough to do any real work. I could go on for hours about what percentage of exercises was just blatant plagiarism. The exceptions we tend to pick up in our lab, though. But I understand it, I also had too much work during the studies to sit down and do real research.

Teaching is indeed a really complicated matter, where you need to ispire, incentivate and motivate students and it requires lots of work, attention and preparation.

I'm actually not involved in the teaching anymore since I'll be likely moving lab soon (tm). But I'll mention the ideas to Gianni for this year's course.

Maybe they would be more motivated if they can get access to the real GPUGRID supercomputer instead of a regular PC. Well, if I was a student again I'd be thrilled to have access to this mighty plaything ;-)

Great! Whatever the outcome, thank you for your positive attitude.

To solve this continuous shortage I suggest a backup project within the GPUGrid project, which has the lowest possible priority. This could be a totally different research, I think something like protein folding (I'm not sure if the ACEMD is capable of this). My other thought is a very large molecule which take very long time to simulate, but the simulation is split up to vast number of pieces. Perhaps those who start this research, and those who will finally analyse the result will be different scientists, but if the science is the same it could be done.

I would to add to you discussion at this point:

I run a ASUS GTX1070 Strix 8 gig and my work units complete in under 13 Hrs every time, this while running Universe@home on the CPU to keep it busy while crunching GPUGRID.

You will be very well of getting the 1070 and if you could get the 1080 do it.

Just ensure you get a GPU with Samsung RAM as there are manufacturers that used other RAM that is giving problems.

One more comment from my side, if I may. From my experience the performance gain of the 1080 over the 1070 (OC) in terms of crunching is very little whereas the purchasing price is 50% higher. Retrospectively, I would not buy the 1080 again but stick to a good overclocked and silent 1070. The 1080 may have advantages in gaming.. but those are of little importance here.

I have two 1070s in my main rig because I took into consideration crunching speed, power consumption and SLI frame rates at 4k. So far, I'm very happy. Although my only complaint is when an exclusive application is running and then closes only one of the GPUs fires back up for a WU. Both WUs say they are running but one of them is at 1600mhz core but 0% gpu load. It never goes away on it's own and I have to restart the computer to get the 2nd card to do any crunching.

Sometimes if I have extra work units on one machine and one isn't doing anything I abort the spares and quickly update GPUGrid on the idling system, seems to work pretty well.

And bone dry again... seems that we can go over to crunching even more complex molecules, can't we? Cut them into slices and we get plenty of work for everyone... hopefully.

Hell, I'm even struggling to get short units, most of my GPUs are idle or doing other projects unfortunately just to keep my house warm.

The tasks are very low at the moment, only 73 to send. I hope this doesn't mean the start of another shortage again.

We are almost at the critical point again where people's GPUs will be idling due to lack of work, we only have 2200 running with 0 tasks ready to send.

I woke this morning and checked the status of processing only to find the system idling, is there currently a work shortage? I set the system to run Seti Institute date, however, I would much prefer to be running protein simulations.

yes, there is.
This happens once in a while.
