Trotador, I would suggest you abort it, if you haven't already.

Beyond, I have no idea why 51% of people do anything they do - I don't even ask anymore.

Why would people complain when things are working?

That was worth getting up early to read.

Like electing (sort of) gwb twice?

I've had a couple WUs seem to stall lately and when I vnc to the machine there's an error message saying the acemd app has had an error. If I close that box the WU restarts from zero, but if I shut down BOINC, then hit the X on the box, and then either restart BOINC or reboot the PC the WU progresses normally. It seems better to reboot because restarting BOINC sometimes causes the WU to progress at about 1/2 speed. A restart gets the GPU running normally again. BTW, the above order of the steps is important:

1) Shut down BOINC.
2) Hit the X on the error message.
3) Restart BOINC or (preferably) reboot.

BTW, all these boxes are Win7-64.

I'm sorry if you think that I was complaining, I was under the impression that maybe I'd get some help here. I've had 3 successful SDOERR tasks complete normally in the expected amount of time, and 3 NOELIA_klebe tasks that run painfully slow, most likely to end in error. I have a 4th NOELIA_klebe at 11% that's been running for 13hrs 15mins that I'm about to abort. I am in no way saying that they can't be successfully run on the Linux platform, just trying to find out what's going on so that I can get it corrected.

Here is a link to the problematic host's tasks
http://www.gpugrid.net/results.php?hostid=151979

Also, I did enable coolbits (GPU temps are around 41 degrees C) and set PowerMizer to prefer maximum performance. Also, I decided against aborting the current NOELIA_klebe task in hopes of using it for troubleshooting the problem. I've tried shutting down BOINC and rebooting, nothing's changed & still running slow.

Any suggestions?

Thanks,
Steve

Hi Steve, the temp suggests to me that the WU has stopped. That happens now and then on windows too. See my post just above and see if that gets the WU moving again (with or without the error message). I'd try the reboot option as the GPU may have gone into an idle state (slow but still slightly processing). Shut down BOINC first and THEN reboot. Hope it works for you.

The latest Noelia seem to take more time to finish than an earlier units.

Here is a unit completed just a little while ago. It completed in just over 12 hours:

http://www.gpugrid.net/workunit.php?wuid=4468403

While a unit complete on May 9, finished in a little over 9 hours:

http://www.gpugrid.net/workunit.php?wuid=4438103

Anybody else notice this?

So far, I have not experienced the blue screen, with these unit, and I had only about 4 or 5 error out, but those units were the "Too many errors (may have bug)" units, so that doesn't worry me. At last count, I have 97 completed and valid.

On my GTX285 and GTX550Ti they take between 41-42 hours. The previous ones around 30 hours. With no errors, but my systems crunch only a few though.
The ones from Stephen, SDOERR take roughly 28 on my rigs. As of yet without error as well.

Greetings from TJ

Bedrich, your runtimes for the current Noelias vary from 33ks to 43ks on the one host I looked at. That's a lot.. I'd look at GPU utilization fluctuation, try to free some more CPU cores (if they're busy with other tasks) and see if GPu utilization stabilizes. I don't think this strong variation is inherent to the WUs.

I haven't noticed them getting longer lately but they're definitely longer than is comfortable for my GPUs. In fact I move 4 of my cards to different projects when NOELIAS are the only WUs available. Not sure if the length is necessary or just an arbitrary choice. Strongly wish they were shorter though.

My observations on NOELIA WUs on my GPUs:

1) They're the longest running WUs I've seen at GPUGrid.
2) They're the most troublesome WUs I've seen at GPUGrid.
3) They have the lowest credits/hour of any long WUs.

Something does not compute (pun intended).

Too late to edit my above post. New NATHANs just hit and they're SLOWER than anything I've seen yet at least on my 4 GTX 460/768MB cards. Not sure how the credits/hour will play out but since they won't make 24 hours it won't be pretty (at least on the 460s). Haven't hit the 650 Ti GPUs yet. But really, I'll ask again: Is there a good reason that the WUs have to be this long or is it just an arbitrary setting?

Basically, the amount of information included in a model determines the runtime. The more info you put in, the longer it will take, but the more accurate and meaningful the results can be.

I have 1 cpu dedicated to 1 gpu, and I haven't changed that.

The way I understand it is that the complexity of the WU determines the time for each time step (in the range of ms). The amount of time steps should be rather arbitrary and choosen so that the server is not overloaded.

This particular unit was a nasty one for me.

http://www.gpugrid.net/workunit.php?wuid=4452849

It caused my computer to shut down and it caused 2 other units, which were running well, to crash.

I've done 7 total of the new Nathan's & they're giving credit of 167,550. 6 of the tasks ran 47K seconds on GTX660Ti's, and 75K seconds on a GTX560Ti.

Looks like, I pulled this one out of the fire:

My 680 is crunching Noelia task in about 300000 s. Other tasks (Sdoerr and Nathan) are ok. I have updated driver to last 319.23.

Are they really so long?

Zdenek

My 680's are taking right around 29,000, that's at 1175MHz Windows XP x64.

I have times around 29000 week ago. Maybe something with driver.

What clock speed is you're 680 running at? To be honest, I think you're in the pipe 5x5 (just right).
