Until thursday cuda-sieving run without any failure. Since then every task abort with following stderr:

System is Ubuntu 10.04.1 LTS Linux 64-bit (kernel 2.6.32-26-server)
Does anybody could give any hint ...

I don't know if it's related, but my CUDA tasks are now taking about 21-22 minutes, vs. the 18-20 minutes they were taking before. It appears as if something changed.

I think John mentioned something about transitioning to a new phase of work.

Just started a test run on the 460. It has already passed the point where it failed on your card. Could you start a second run to see if it fails at the same point again? In your first post it failed at p=1507576042643183.

Yup. Repeated crashes here too. I've read about problems with the 260.19.xy driver series and the reports seem to be true.

I think this is a driver problem. I have no problems with my 260GTX with driver 256.44. After downgrading the driver on my other computer (2x460GTX) from 260.19.xx to 256.53 i have no errors. I test both driverversions of the 260.19, i get errors with both.
Both systems run with Debian GNU Linux testing.

Interesting. I sieved several thousand G for PSA (PPR3M) with tpsieve and Linux without problems. I'll send Ken a PM.

Message 28385 - Posted: 26 Nov 2010 | 19:22:30 UTC - in response to Message 28384.

I suspect the bug with 260 drivers is a timing issue. Manual sieving usually uses the non-BOINC version, which has a separate thread for sieving.

I'm using the 260.19.14 driver, and I haven't had too many problems yet; but I haven't tried the newest work.

I'm using the 260.19.14 driver, and I haven't had too many problems yet; but I haven't tried the newest work.

The test which crashed was a "new WU" with an exponent range from 1-3M. My Linux PSA sieving (PPR3M) work had a lower exponent range (-n 2M -N 3M) and the GPU worked without flaws with the 260.19.xy drivers*. Sysadm@Nbg's box worked without problems until yesterday. Around that time the new "shorter" WUs with the larger exponent range were introduced.

*With one exception: The -m 64 problem that I've reported earlier...

With the old Workunits (1800 credits) i had also no problems with driverversion 260.19.21, but after PG send out new work (2314 credits) all wus ended with error.

tested driver on 460GTX:
260.19.21: works fine with old workunits, error with new workunits
260.19.12: erros with new workunits, not tested with old
256.53: works good with new workunits, not tested with old
256.44: works fine with old and new, but is 40 seconds slower on old wus in comparison with 260.19.21

256.53: works good with new workunits, not tested with old

I became some resends of old workunits and i have no errors with 256.53. Looks like that the driver is faster than 256.44.

For those sticking with 260 drivers (or unable to leave them for some reason), it looks like adding "-m 8" to the command line may make the results better for Fermi users. I believe you can add "<cmdline>-m 8</cmdline>" to your app_info.xml file after "</coproc>", but I wouldn't swear that's right.

Likewise, it would seem that "-m 2" allows my GTS 250 to run these new WUs without errors.

Could these cmdlines be implemented project-side pleaaaaaaaaaaase? Otherwise I'll need to do all the app_info kaboodle. :(

I've already asked to get a new client installed with -m 8 default for Fermi. As for -m 2 and a GTS 250, though, that's just way smaller than it should have to be.

By the way, I got a mod at nVIDIA interested but not yet convinced. Can anyone verify that a particular command line works with earlier drivers but not with the current ones? Try one of these programs and a command line like this, for example:

./tpsieve-cuda-(version) -p420700e9 -P420701000e6 -k 1201 -K 9999 -N 3000000 -c 60 -M 2 -T -m 64

Not where I can test now, but the -m2 option was always fastest on my G92 cards (8800GS, 9600GSO, 9800GTX+) of which the GTS 250 is one...

After work (22:00 UTC) i can make same tests with the 260 driver. I can also make same tests with 260GTX if needed.

2xGTX460 driver 256.53:

<cmdline> -m 8</cmdline> works (same runtime, same cpu-time; but i had only time for some fast tests)

depends on the number and organisation of cores.

my GTS250 (128:64:16) get's really slow with -m 6 and ins fastest with - m 16

As for -m 2 and a GTS 250, though, that's just way smaller than it should have to be.


I've tried all values between 2 and 8. Most bail-out within 30 seconds, some sooner. Should I try higher values?

Also, I've rebuilt the version in your git repo against CUDA 3.2, and get the exact same behaviour. (and roughly the same performance), so CUDA version doesn't seem to matter.

maybe the linux-app is behaving different - i'm running win64..

I'm runing linux64 with the older kernel 2.6.27-17 and driver 195.36.31 (cuda3.0). Your kernel is 2.6.37-3 and we don't know your driver-version. IIRC, cuda3.2 needs a driver higher than 262.x

By the way, I got a mod at nVIDIA interested but not yet convinced. Can anyone verify that a particular command line works with earlier drivers but not with the current ones? Try one of these programs and a command line like this, for example:

./tpsieve-cuda-(version) -p420700e9 -P420701000e6 -k 1201 -K 9999 -N 3000000 -c 60 -M 2 -T -m 64

1. You have to use the BOINC version to get errors, it appears. Edit: Yes, I mean tpsieve-cuda-boinc-(version).
2. Please delete any tpcheck*.txt between runs.

- all tasks with driver 260.xx have errors, but the the number of factors before the task aborted is differing

So, basically, we linux users need to downgrade to nvidia driver 256.xx?

That is the best option for now, yes. The second-best option is to include a -m argument with a low value in an app_info.xml file.

Maybe a bug should be filed at Nvidia?
If this is a real driver-error it should be fixed by the developer of the driver if think.

http://www.nvnews.net/vbulletin/showthread.php?t=157563 New nvidia BETA linux driver released today. It's lacking an updated changelog, so no way to know what's different/new.

I just tried with this new driver, and continue to have the same problem; just in case anyone else is inclined to test the new version, it won't help this.

They did however fix being able to change the clockspeeds through nvidia-settings, though, so some people using the 260 driver might find it useful.
