ready for some Fermi numbers? GTX 480

[eternal_fantasy]

Just last night I was able to pull one 6.73, which error'd out in ~10 seconds, then was back to beta units. Then hour or so later of betas, another 6.73 popped up, which has been running for 5:32, at 94%, so should be completed with a total time of 5:53. This is on a PC running at 4.16Ghz 980X, HT ON with 12 WCG work units. 480 at 800Mhz core, 1900Mhz Mem, and with 57% utilization crunching the 6.73 WU.

I've only selected the "ACEMD" application, with the "ACEMD ver 2.0" and "ACEMD beta" unticked.

If you only want the new 6.73 WUs you can opt out of "Run test applications", but be warned that the new WUs are quite scarce, so your manager may need to spam the GPUGRID server for a while before getting a unit to crunch. I selected "yes" to "Run test applications" to receive some beta test units to keep my 480 busy whilst waiting for one of the new units to show up, which seems to be around an hour or so of betas.

ryan, you may need to wait a few hours for the older WU's to get flushed out or for gpugrid to recognize your updated preferences . i was still getting beta units for a little bit until a few hours later. or maybe restart BOINC

Are you talking about the queue thats on the computer? because I already aborted all the other WU's. Well either way I'll leave it running overnight to see what happens but I don't think I'll get a piece of PIE tomorrow.

once you deselect the 2.0 and beta ACEMD applications, "no" to "Run test application", and "If no work for selected applications is available, accept work from other applications?" to "no", you will not be getting anything else other then the new 6.73 units. But as I have said above, they are scarce at the moment so be prepared to wait a while whilst the GPU sits idle for the new WUs.

What you are already crunching/waiting to be crunched on your computer is irrelevant to what work units you will get next.

Also, my preference set over on GPUGRID seem to be almost instant, once set and selected to "update" the GPUGRID project in the manager.

Just got a 6.73 WU and basing on the 5% mark looking at 40k ppd. Thats only running at 0.10 cpus on win7 64.

And it is done;

2284093 1440600 5 May 2010 23:52:27 UTC 6 May 2010 6:08:25 UTC Completed and validated 21,265.93 20,168.32 7,954.42 11,931.63 Full-atom molecular dynamics v6.73 (cuda30)


Total Run Time 05:54:25, 11,931.63 credits, so around 48476 PPD just with this one work unit... however it seems I'm back to crunching betas for now.

edit: Ah sweet just downloaded another 6.73

How much is your cpu set to? Do you have a dedicated core for it?

I have the full CPU thread setting configured. I don't have a dedicated core for the GPUGRID, as there are some downtimes with WUs from GPUGRID drying up for periods of time, and don't want to waste CPU cycle.

However I have a lower priority set for the WCG, at 80, so when I do have something to crunch GPUGRID gets priority on one of the cores, while one WCG WU thread waits with 0% CPU utilization.

Okay just just changed the SWAN_SYNC=0 and running 12% instead of the typical 5% lets see what happnes

[WhiteFireDragon]

mine finally just finished, it took 7h 20min (26,452sec GPU, 26,158sec CPU). i'm not sure why it's significantly lower than everyone else's. it's slightly overclocked, and i dedicated a whole thread to it with SWAN_SYNC too

btw, congrats ryan, you made it to the first page of our team

[=[PULSAR]=]

WFD I think it because me and you are the only ones using official drivers if you look everyone else is running betas

EDIT: First page of what? lol

alright, time to switch drivers to see if there are improvements. i'm just going top copy etherna_fantasy's and use 197.44 unless there's any objections. it's weird how official nvidia driver is 197.41, which seems older than 197.44. so where can i get these "official" older drivers without having to DL from some untrustworthy site?

first page, as in top 20 of our gpugrid team . i'll meet you there in a few days

[=[PULSAR]=]

I would just go with 197.75 found here. Seems like some people are having goodluck with them.

I'm waiting till tomorrow to see how this first 6.73 WU does. They need to fix that OC bug for Fermi's I can fold all day at 850 core but it would be pretty beneficial to unlink the shaders and raise them more

[eternal_fantasy]

I downloaded my 197.44 driver from HERE, which is Nvidia's official OpenGL 4.0 driver, provided by Nvidia's official site, which is not supported by any other version.

[=[PULSAR]=]

Just gave the beta 197.75 drivers a shot my 6.23 beta went from 590 seconds down to 497 so I would call that a vast improvement.

EDIT: was looking at skgiven's stats and showed a huge difference.

v6.23 beta
XP x86 - 325 seconds
win7 x64 - 600 seconds

That pretty much sums it up.

[WhiteFireDragon]

i tried the 197.75 beta as well. the v6.73 WU's when from 7h 20m down to 7h exact, and the v6.23 beta WU's when from 685sec down to 650sec. that's about a 5% in time reduction on both. still not as good as i wanted, but better than nothing. i'll be trying out the openGL 4.0 driver later to see if i get even more improvements.

yeah i mentioned earlier on skgiven's results on his gtx470. he's getting 4.8 hours on XP with v6.73 WU, while my 480 gets almost 8hours on win7, and only difference is OS and drivers. for people crunching with both WCG and GPUgrid, there's a dilemma of which OS to use. XP gives much better results for the GPU, while win7 gives better results for the CPU. which to use ? how does linux compare to XP for gpugrid?

[pwolfe]

I still don't understand how you guys are able to pull WU's. I mean I can't possibly be that unlucky to have not pulled a single beta or acemd unit this whole time. I wish some of you guys ran Linux so we could compare notes. At this point I'm assuming there is something wrong with my setup that is preventing me from getting a WU. My gpugrid pref's are identical to all of yours and I set this machine up with a clean install exactly as I have many times before. Frustrating.

[WhiteFireDragon]

i think i might know why. which drivers are you using? the profile of your computer with the 480 doesn't show which nvidia driver it's using, so if you're using generic drivers, that might not work. i think when i used the drivers that win7 auto-installed, it could not crunch because i believe it didn't have CUDA drivers.

if you're having this much trouble with linux, i would just switch to win7 or XP (preferable XP since you get almost double the computational advantage) so your card has something to do. it's one expensive card to just be sitting idle.

[Danger30Q]

I haven't been able to get any new work units today but my time is still around 1100 seconds for my GTX 480s at 775/2000. I updated to the 197.75 beta drivers and BOINC tells me no GPU detected. I really haven't had time to seriously troubleshoot these problems but hopefully I can tonight or tomorrow assuming I get more work units to test.

[WhiteFireDragon]

i hate babysitting my these new cards too, and without the application fully supporting the cards yet, i can't afford to keep mine. i'll be listing both of them in the FS section soon, so if any of you guys want it, PM me and i'll sell it a little cheaper than to other non crunchers.

[=[PULSAR]=]

Which cards are you selling? Don't give up just yet

[WhiteFireDragon]

i'll probably be selling one, maybe both of my 480's. i'm glad i left one of them unopened. the numbers on these cards are too low for how much i spent on them. i'll be replacing these two cards with an army of gt240's

[pwolfe]

I'm using 195.36.24, the latest stable Linux drivers, BOINC has never reported my driver version correctly, even when things are humming along smoothly.

How about a trade for a gtx 295

[eternal_fantasy]

Hmm.. I'm currently crunching a 6.73 which looks to be complete just over 5 hours...

It is currently at 75% and 3:54 hours in... I'm running Windows 7 64-bit too, but I disabled Hyperthreading, and only allowed WCG to run on 5 cores, with one left for GPUGRID, which when the 2 are running the CPU is at 100% utilization for all 6 cores.

It's interesting that the CPU plays a much bigger part then the GPU for these WUs at the moment.

Mine finished in 5:57 looks like the extra cpu percentage really matters. What kind of clock were you running on your cards?

800 Core, 1900 Memory. However seeing the GPU usage is only around 60-65%, I'm not sure how much it matters at the moment, at least until the code is more optimised to be crunched on Fermi GPUs.

I do wonder how upping the CPU speed would affect GPU usage, as it seems is what's bottle-necking the GPU at the moment...
