Hi all,

New WUs in the long queue, big-box size, 120000 credits each. The batch has been previously tested and should not report any issues, but please comment any problems you might have.

Noelia

These slow a GTX 460/768mb GPU to a crawl. Santis and Nathans run fine.

I run these on both the machine with the Titans and the one with the 2GB GTX 650Ti.

The Titan box runs these (as well as Nathans and Santis) roughly three times as fast as the 650Ti does.

I'm thinking about firing up my old box with the 590s in it to see what that will do in comparison.

Operator.

running at 95% gpu load on gtx 660 ti in windows 7! really nice!

Yes, I finally got one too. Running 92% steady on my 770 at 66°C.

It is running at 96% on my GTX 650 Ti (63 C with a side fan). At 60 percent complete, it looks like it will take 18 hours 15 minutes to complete. And no problems with the memory (774 MB used).

Just got 80-NOELIA_INS1P-5-15-RND4120_0. It really is putting my 650Ti through its paces!

vagelis@vgserver:~$ gpuinfo 
    Fan Speed                       : 54 %
        Gpu                         : 67 C

        Free                        : 85 MB

The WU is only at the start (1.76%) and estimates to take 22:44. I expect this to drop significantly.

Undoubtedly why they won't run on the GTX 460/768 cards. They work fine on my 1GB GPUs, but I have to abort them on the 460 in favor of Santi and Nathan WUs.

Finally I had another Noelia WU. It ran steady on my 660 with a GPU load off 97-98%, Nathan's do only 88-89%. And it ran in one go, that means no termination and restart because off the simulation becoming unstable.
I wish I could opt for Noelia WU's only.

I noticed a lot of failures on the 400 series cards and almost posted about it, but wasn't sure why. I think you have explained it.

Finished successfully in 81,572.91 sec (22.7h) on the 650Ti (running on Linux). Didn't actually take 18-19 hours, like previous NOELIAs.. must be a more complex WU.

180k is sweet! :)

Sounds like the minimum GPU memory requirement is set too low for these, otherwise BOINC would refuse to run them on such cards.

MrS, can the minimum memory requirement be set for specific WUs or just for the app in general?

I don't know, I've never set a BOINC server up or created WUs myself. But if I had programmed BOINC this would be a setting tagged to each WU, because that's the only way it makes sense. The entire credit system was based on the idea that different WUs can contain different contents.

So I'm not certain, but expect it to be possible. And if not a feature request is in order, IMO.

I believe it might need to be set at the plan_class level, which is between app and WU.

So we might need to enable something like cuda55_himem, and create _INS1P WUs for that class only.

I just had a work unit fail (on an otherwise completely-stable system):
http://www.gpugrid.net/result.php?resultid=7285706

The error seems to indicate, to me, that it's likely a problem with the work unit. Can you (NOELIA) confirm that? Also, if there's anything else I can provide, let me know. Thanks, Jacob

It's failed on every other host too, so it's a bad workunit.

Just spotted a NOELIA_INS1P at 123h into a run, and only at 43% complete!

I suspended it and tried to get it to run on the other card. It started but the system became unresponsive (mouse stopped moving then started, but couldn't click on anything). Then CPU WU's started to fail and the system became totally unresponsive (to keyboard and mouse).

The WU has already timed out on the server,

pnitrox120-NOELIA_INS1P-3-12-RND7171_0

Would have been good to have spotted this earlier, yesterday, the day before, the day before that... Oh well, it's your loss too I guess.

After hard powering down and cold starting the system up again, the WU resumed on the other card but says it had only run for 6h 45min. This suggests it went wonky around that time and ran cold thereafter (GPU was at 45C). It's running on an 8.03 app (Ubuntu 13.04, CUDA55) and it's looking like about 6 or 7 hours to completing, so I will let it run and keep an eye on it.

That is what still concerns me. I can take errors, but stalling a machine may be even worse than a crash.
