Hey guys,

I have put some new work on the long queue. These workunits are small and don't require any special algorithms, so should be no problems.

With these workunits, I'll be looking at the folding of a small peptide using a special force field. The biophysics community uses different force fields to represent the motions of proteins and other molecules, and we are attempting to test a new one so we can check some previous work and feel comfortable in work we are planning to do.

Happy crunching.

Nate

I'm currently running I62R8-NATHAN_KIDc22_2-0-8-RND1007.

KIDc22 is new to me: been running (steady progress) for nine hours on a GTX 670, and only reached 78%. That's hardly 'small' - in fact, the slowest I've seen.

I think Nathan's referring to some new ones, not the NATHAN_KID. That's why I asked the question above...

This is confusing, these are new to me, I never saw them until yesterday. He must be running 2 different kinds wu's, I guess I'll find out soon enough.

The last WU in the database (a few seconds ago) was http://www.gpugrid.net/workunit.php?wuid=4476102 - and it's a NATHAN_KIDc22

Thanks, Nate.

My 580 has little trouble finishing them in 24-hours, but my 460 takes about 25.5 hours to finish one. It would be nice to have WUs that finished on 460's in under 24 hours.

I received 3 running Linux. All ran fine and completed in about 11hr20min on a 660TI. I then booted into XP and ran 2 more. They also ran and completed without issue but actually finished them about 10 minutes faster than Linux. Love the credits.

Yes, the WUs are called NATHAN_KID... workunits. I should have mentioned that Initially. There will be some NEW new stuff soon as well, but I won't make a new post, but update here. There will also be a new batch of WUs coming from a new scientist that will go on the short queue. That will be announced in a new thread.

Ok, there are two groups from me on the grid right now:
NATHAN_KIDc22_2
NATHAN_KIDc22_SODcharge

So you guys know. The second group might run a little faster. You'll have to tell me.

I'm currently running http://www.gpugrid.net/result.php?resultid=6905151

on a 660Ti @ 1137Mhz / 3019Mhz
and it's taking about 381 seconds per frame.
Which puts it at around 10.5 hours runtime.

kinda poor GPU usage at ~85%.

I've finished 4 so far, GTX680 took 9 hours 40 minutes, GTX670 about 10 hours 167,550 points.

I’ve done two NATHAN_KIDc22s on my stock-clocks GTX 660. Both kept one CPU core fully occupied (acemd.2865P.exe), and both used a modest amount of GPU resource; see snapshots below.

The first took 15h31m of run time for 167,550 credits, the second 12h27m for 134,000 credits.

Thanks for the info. The SOD WUs do run faster and they just barely allow a GTX 460 to slip under the 24 hour mark (if micromanaged). So for me it's a large improvement, but still on the long side.

Micromanagement drill: set a backup project, set BOINC to report immediately: then DL a GPUGrid WU, then turn off GPUGrid work fetch, then wait until you notice the GPUGrid WU is done and the backup project is running, then turn on work fetch to DL a new WU, then pause the WU from the backup project so the GPUGrid WU starts immediately, then un-pause the backup project WU so it will run again when the GPUGrid WU finishes. Repeat ad infinitum... If you're lucky you've squeaked under 24 hours.

I acknowledge the new NATHAN WUs, I'm about to finish I84R7-NATHAN_KIDc22_SODcharge-0-10-RND9833.

Runtime, just above 18h on a GTX 650TI on Linux x86_64.

Nice-behaving, these NATHANs! Keep 'em coming, Nate!

If I had unlimited money I'd buy the fastest GPUs available. Some of us are retired and on fixed incomes. Buying less expensive cards and paying the electric bill is enough of a strain. Of course if you send $$$ I'll certainly purchase some GTX 660 GPUs ;-)
JK, BTW: congrats on your GTX 660, it's a nice card.

Me too, but I had a strategy vs. She who holds the purse strings and must be obeyed. We replace our rigs every four year. My rig is almost four year old. She was persuaded that changing the PSU from 425W to 620W, and replacing the video card, was a better alternative to a new PC!

BTW: congrats on your GTX 660, it's a nice card.

Thank you! Love it!!

Did the usual drill: shut down BOINC THEN hit the X on the acemd error message then reboot (as the GPU can sometimes become unstable when this happens) It eventually finished successfully (and I beat the 24hr deadline by 12 minutes!). This WU failed on 2 previous machines:

12mins?

I should feel especially lucky then... to get this (I10R4-NATHAN_KIDc22_2-6-8-RND2039) in with 51secs to spare. :)

GPU-load was 90%.

I'm getting system restarts while running NATHAN_KIDc22 WU's on XP-x86.
The only other app I have running is WUProp (NCI).
The tasks are recovering however.

A different type of problem this time:
The WU ran for 29h but had only reached 30%. There was an acemd.2865P.exe pop-up error sitting on the screen when I checked. I exited Boinc, restarted and got the same error, however the Elapsed time now told me that the WU had only run for ~5h30min. When I suspended the task the error message disappeared. I started to run a different WU (from GPUGrid, then suspended it and ran an Einstein WU, which had been suspended), then suspended it and tried to run the Nathan WU. After about 10sec I got the same error message. I closed the message and the task went to 100% and Error after ~10sec.

I have had two WU with the same error:

I36R2-NATHAN_KIDc22_2-3-8-RND5161_8

Run time 11.7 seconds. CPU time 0.55 seconds.

There are seven other error reports on this WU all with very small CPU times.

and an older one

I55R4-NATHAN_KIDc22_SODcharge-1-10-RND5713_0

Run time 140.58 seconds. CPU time 99.79 seconds.
There is no other error reports and one completion report for this WU.

WU's can fail many times. I had one which failed 8 times and at the last one succeeded. So I think it's not really any indication.

The computer it failed on was a titan (which cannot run these WU's):

    Coprocessors NVIDIA GeForce GTX TITAN (4095MB) driver: 314.22



If a WU fails on several known good systems then perhaps there is a problem, but you have to dig deep to find how reliable the previous systems were.

In the case of the GTX570, it's most likely that the GPU clocks dropped, but these were not reported, and neither was whether the system is set to prefer maximum performance, or how much the of CPU was being used...

The recommended settings are list in the FAQ's, and there is a suggested way to ask for help (because we cannot see your systems setup).

This system does this RNDXXXX normally in around 58000 seconds, and has done so quite a few times, so this is really a strange WU. I never had issues with the system although this RND tasks takes quite long for one of the faster Video cards of the last generation.

Video card is EVGA GTX 570 SC (not further pressed, I prefer that it is running more or less cool with 68º to 73º C Fan speed at 85%) and on the AMD 6200 FX there is a core reserved for the Video card as recommended. The card is a recent replacement for a faulty card by EVGA, so new.

Oh, and I just noticed the up-load file does have a size of 107.88 MB (so more or less the double as before), therefore it will take quite a while until it is up-loaded, as my internet connection will brake several times and will end up with the famous 5 hours brakes between each up-load try.

Klepel, as you say you've been running these Nathan KIDc22 WUs just fine before in 59ks. Check if the GPU clock is still up to where it should be. After driver resets it sometimes stays too low without throwing an error at GPU-Grid. In this case a reboot would help.

The strange WU is up-loaded: http://www.gpugrid.net/result.php?resultid=6930954

All seems normal. Only that it took nearly twice as long: 101,479.54 s
Stderr output: 57186.919 s

The next WU crashed, because of a electricity cut.

I will inform about the next WU after it's finished.

Your 2nd wingman handed the WU in after it got sent to you, but before you could send your in. In this case the bonus credit doesn't trigger for both of you, sadly an old problem.

Ah! I did not notice I had a wingman. I had thought GPUGrid's quorum was one. Why did it get sent to me before the wingman's try had run out of time?

It's a known issue with the credit system at GPUGrid. Basically it happens only when a WU is resent and after being resent is returned by the first recipient and validates. Subsequent to the validation bonuses are not awarded. It's a fairly rare event but apparently too difficult to fix.

No Bonus for finishing within 24 hours

The WU was sent to the wingman first, but he didn't return it within a few days. At some point GPU-Grid needs the results to generate the next WU in this string / time iteration. So the WU was sent to you (not sure if this was before the deadline for the wingman or not), but the other guy evetually handed the result in. This is why GPU-Grid is not suitable for low-end hardware and why the deadline is rather short.

Do you have an Eltron chip? They had serious driver issues last year, leading to unstable transfer rates, devices dropping and unstable computers. Drivers from this spring are fine, though (using it myself.. guess why I know about the problems).

Yes a lot! I know...
The first ones, from the end of May and the begin of June, I had some difficulties for a stable core clock and shader speed. Because my GTX570 are a little bit overclocked by EVGA and I was starting on a new system, so I had to figure out the best settings.
After that a few WU's were going good and since last week I had only errors. It's very frustrating... and I don't know it has to do with the WU's or my computer... hmm. Disappointing.

I'm running @ 680MHz core (1360 shader) and 1700MHz VRAM. Default on my cards is 732/1464/1900Mhz. Very strange, at my formal system I've used thems on 720/1440/1700 for stable clocks. Back in Februar I had mostly good and validated WU's with those settings. Strange...

You might need to tweak your Voltage up slightly on your GPU.
Is it clean and is the PSU up to the task?

Higher voltage even now when I've lowered the speeds?
My PSU is good (Corsair AX850) and stable for what I know.

All the hardware runs at a benchtable, in open air... I've cleaned all components before I started end May with folding again. Removal of dust, new cooling paste, etc...

With the same hardware I'm running Primegrid, PPS Sieve CUDA based and Genefer GFN CUDA. That's a higher load then GPUGRID (99% vs 80-85%). Only 1 GFN task had an error last week (by my own fault), 1 of 6 tasks... But I'm going to monitor if it occurs more frequently in GFN than I thought, so we could exclude what the problem is (my computer or any folding program).

Boy, this place is turning in to you're own private Idaho, nobody else wants to run work units? Not that there's anything wrong with yours.


:) Well not intentionally. The current WUs are part of a rushed project we will hopefully be able to publish quickly. Also, I often run projects for other people/collaborators, since I am one of the most experienced here. Santiago (the new guy) will have the short queue mostly dominated for a while with a very interesting project, so it's not only my work being done.

I'm back! :D
PrimeGrid challenge has finished and lightning storms are gone for now... so we can maybe fold again. ;-)

Before of all above I've runned last week eight GFN cuda tasks (12 hours per WU) and a few (20 or so) PPS Sieve tasks. All tasks are succesfull finished, so I don't think my computer is the problem of all WU errors at GPUGRID. But it's still strange in my opinion why PG WU's can finish completely and tasks from GPUGRID don't.

Not really that surprising as in some projects like PG I don't expect them to try anything new. They just continue the same type of WU's they have tested forever. We have every time a new biological system, often including new functions. So I guess, shit happens :D (quite often)

Wow, I didn't realize that, it clears up a lot of things. I imagined for some reason that you guys had made up some sort of templates in the beginning that could be used over, now I understand a little more of the difficulties. What about Cuda 5.5? Now that it was just released, could it be of any use to the project?

No idea on CUDA. Gianni knows more, but I think he keeps a pretty good eye on CUDA releases, so when they actually provide a significant boost we use them like in our last update.

I haven't had any issues with nathan tasks. My 680s clear them in around 8-10 hours depending on the WU.

FWIW, my 660 (singular) has processed 46 of the new batch of Nathans, that first appeared May 27. They take 12h30m to 15h:30m, depending...

Four WUs died with errors, losing 18 hours of crunching; a dfhr36 and three noPhos.

My 660 has been knocking them off in about 39,500 seconds (just under 11 hours).

I wonder why my 660 takes so much longer than yours?

It is all down to my Win 7 vs, your Ubuntu, or is something else in play here?

It looks like mine is about 12% faster on average. That could be down to Win7 vs Linux. I'm not running regular Ubuntu either, but Lubuntu with MATE. That avoids the bloat of Gnome3.

It might be worth trying to boot off a USB flash drive with Linux and run a WU or two to compare the difference on your setup. I've heard CPU and RAM can also play into running time. Additionally, I have an Asus 660 OC that I believe runs at 1020 MHz and 1085 MHz boost.

I have no idea how to do that!!!

I have an Asus 660 non-OC but I pushed it up to 1097 MHz, with no ill effects...

My 660 is an EVGA not OC and runs at 1110MHz. It needed around 46000 seconds to complete a Nate's long run. Win7 ultimate with 12GB RAM, 5.5GB in use and 88% of the CPU, i7 960 Bloomfield.
So you GPU is a lot faster.

It's your driver, that's the first thing mentioned. Just when you call IT with a problem, the first thing they jell is: did you reboot?

By the way my 770 in the AMD finished a Santi that failed on your 770, same driver though.

The last 5 Noelia's I got, finished all without error. I like to take them all...

Yes, I reboot all them once at day at least. Well then there is a problem with 320.49 and noelias, because it works with the other units. The problem is: no other drive will work with the 3x690 rig, and the one with 2x690+1x770 have issues aswell, but at least other drivers will recognize all the gpus.
Other drivers will lead to all sort of problems, including heat control and stability, things that i can´t leave behind.
So noelias are no option for me, sad.

I don't think the 320.49 driver is the problem. My re-newed rig with FX8350, Sabertooth and Asus GTX770 has done 24 WU's LR and SR, from Noelia, Nathan and Santiago with zero errors since it started crunching. Five cores are doing Rosetta and temperature is still low with stock coolers.
