That usually signifies a memory error.
Have you rebooted your machine and tried another WU?

Yes, I have try to reboot...
All problem start the 6 march
but I haven't change anything !!!
My card have only 256Mb maybe ACEMD - GPU molecular dynamics v6.04 (cuda)
need more ram ?

We have fixed that in the upcoming release, considering special cases where the GPU card does not have enough memory.

My GT240s use between 290MB and 320MB (according to GPUZ), so if you did only have 256MB it might be an issue (as your card has 112 shaders, my GT240 has only 96). It would be interesting to know how much RAM GPUZ says your card has, and how much it is using!

Hopefully the fix will allow plenty of redundant cards to work again.

same problem here, looking at my more recent validated work, its all 6.70 and 6.03, however, its a 50/50 if 6.03 passes or fails. all my errored work is 6.04 & 6.03, still blowing though roughly 10/1 or better WUs erroring out vs running/validating on a given day/machine. variety of cards, CPUs and 64bit OS's. Another common hit I'm seeing is 'SWAN: FATAL : Unable to create context', not sure what the deal is w/ that, but, bottom line it's ~ 0-3sec cpu time and out for these WU's. Reading the moderators comment I'm leaning toward WU vs config issue, if absolutely no WU's were crunching, I would be hunting for a tweak here or there but, I'm still looking for a solution, open to suggestions:)

imcola,
Looks like your GeForce 9600GT on Linux, your 9800GT on Linux, and your GTS250 on W7hpx64 can only run ACEMD tasks.

Your 9800 GT on W7hpx64 can run both ACEMD and ACEMD ver 2 tasks.

I would suggest you select to only run ACEMD tasks.

Alternatively you create another user account and add your 9800 GT on W7hpx64 to that new user account and set it to just pick up ACEMD ver 2 tasks (faster).
If you do, you could create a team and have 2 accounts for the team.

The perfect solution would be for the techs to allow people to configure individual cards/systems online. Lets face it, new apps are needed, so this may be the way forward.


Paolo Biagini,
Do the same, select to only run ACEMD tasks.


To change account settings:
Goto Your Account, GPUGRID preferences, Edit GPUGRID Preferences,

Alter the Application versions as follows:

Run only the selected applications
ACEMD: YES
ACEMD ver 2.0: no
ACEMD beta: no

Why does he need to make two accounts? Why not just use the Default/Home/School/Work GPUGRID preferences? Just use one GPUGRID preference for the 9600GT & another GPUGRID preference for the 9800GT.

liveonc, you are correct - imcola should just setup 2 different profiles; that's the sane way to do it!

Message 16110 - Posted: 31 Mar 2010 | 23:06:26 UTC - in response to Message 16063.

Thanks guys!, back in business, I did end up creating a couple diff profiles as suggested, but once I got home and detached- bounced BOINC and re-attached on the various machines, everybody went back to work using 'home' w/ just original ACEMD WUs, no ver2 or beta work. All except for the gts250, kept saying no WUs avail, so I set 'school' to get both ACEMD original & ver2 ACEMD WUs and pointed the 250 to school, detached/bounced BOINC and re-attached and it took right off after the d/l(s) completed. Cool!!

I guess I still can't differentiate, between the versions beyond v6.70, v6.71, v6.04 and v6.03, but as long as BOINC/gpugrid and the profiles/cards can, I'll be happy to just play along. THANKS again for the insight!! Many happy crunched returns!!

6.03 is for Windows and 6.04 is for Linux - Both are ACEMD ver 2
6.70 & 6.71 are ACEMD
You dont really need to differentiate, just select ACEMD or ACEMD ver 2 for each profile.

6.04 WUs for my linux boxes seem to primarily crash and burn ~ 0-3 secs CPU and out. 6.70 seems to run ok, but it seems there are not so many of those WUs. Is this the case?

GDF, you mentioned a new beta release which would correct errors mentioned in this thread, Linux and 6.04 seems buggy for sure for my 2 boxes. I have set up a 'school' profile to pick up acemd and ver2 and beta, but don't seem to get anything but 6.70 (runs) & 6.04 (won't) (Home should just grab ACEMD WUs, while work should take either ACEMD or Ver2) . This GPUGRID project seems to need some extra help, where as boinc/cpu crunching I can pretty much let it go by itself. If you have some guidance or can use a crunchers feedback, i will play guinea pig for a little while if it will help to bebug this linux side of the project, you might throw me in the deep end from the code perspective, but H/W wise I'm pretty solid, offer extended FWIW. UBUNTU 9.10 on both machines.

BOINC is not able to report your driver version.
Could it be that it's not properly installed?

Good question, I've just updated from Ubuntu recommended v185, and installed 195.36.15 Nvidia drivers on both boxes, Ubuntu sees new version and displays the Nvidia X server settings. But after restarting BOINC, msg is that it sees the card, but driver version unknown and CUDA vers 3000, so I would say yes, they are installed and correctly, but BOINC still seems clueless about them

All of my linux hosts have always reported the driver as unknown.( I think the boinc dev's are aware of this) 6.04 runs ok on my hosts but uses 100% cpu so I have elected not to run them. The ACEMD tasks seem to be running out as I haven't got any for a few days now.

Are you completely mad? Run them, they are not there to look at. They run 30% faster than the other tasks (that have run out).

Let me put this another way.
My highly overclocked i7 does about 1/5th the work of a GT240 (under windows). A GTX260 does about twice the work of a GT240 and a GTX295 does twice the work of a GTX260. So a GTX295 does 20 times the work of my i7.
Your GTX260s would do 13 times the work of an i7 under Linux!

- Give up one CPU core - you have quads and GTX260's!

I even sack a CPU core under Windows, just to facilitate GPUGrid even when it does not need one full core. It's worth it for me using Windows never mind linux!

BTW this is Way OT.

Well I ended up throttling back CPU utiliz to 80% on 1 machine, the other i didnt touch, but I pointed them both to 'work' to pick up some ver2 WUs (maybe). I now have 2 6.04 WUs running and well past the 2sec cpu mark, so I guess, i will kick back and monitor for a few days, see what happens w/ no twiddling for a couple days, be back in a few I guess

Hi Paolo, it took me a few days to get my Linux boxes dialed in to run 6.04 WUs. I have now got 6 validated vs 1 errored out, and 7 more running/queued to go. Let me backtrack, maybe you will spot a prob on yours. I had to throttle back CPU utiliz on one of mine under BOINC prefs, from using 100% CPU back to 80%. Your own earlier post showed your single 6.04 successful run, confirms my work, these 6.04 linux GPU runs are real CPU hogs vs a windows GPU WU, although I have not a clue why a GPU linux WU should require nearly a sec/CPU for the entire run time in secs, while a windows seems to need 10% or less CPU for its GPU run to complete. End result, try freeing up CPU cycles from other projects. See if that helps.
If you dont have the latest/greatest (I assume) Nvidia drivers installed, it was another upgrade for me to get the 6.04 WUs to run clean, you will want to be able to display the NVIDIA X server settings from the OS to confirm good install, not to worry if BOINC still cant detect it, the WU's can tell the diff and were not running from backlevel drivers. HTHs

Everybody who responded to thread, I really had to bang all of your observations/suggestions together in order to get this project back on track/ functional. Thanks, Paolo check back if u r still stuck
