Message 27583 - Posted: 6 Dec 2012 | 10:03:06 UTC

Hi all, I just suspended this task after running for ~9 hours, other > 11 expected on my GTX570 (should I expect ~300.000 credits for this?). First one of this type that I got. While running it used about 10-13% gpu...

Any comments?

The previous NOELIA WUs ran fine for me except for the one I got yesterday:

ala_structure_571-NOELIA_sh2forces-0-5-RND2523

It ran SLOW and only used 13% GPU instead of the usual 90%+. Aborted :-(
I'll wager that something is wrong with these.

+1

It was running for more than 5 hours, even so the running time is 0 according to the task's page.

The last NOELIA task I ran was probably from a different batch,
ptyr_structure_471_bis-NOELIA_sh2NOTCL-2-3-RND8206_0 3905816 139859 3 Dec 2012 | 3:50:05 UTC 3 Dec 2012 | 17:58:33 UTC Completed and validated 50,105.85 7,051.59 102,900.00 Long runs (8-12 hours on fastest card) v6.16 (cuda42)

Perhaps there is an issue with this batch?

If anyone is running one of these tasks, does freeing up more CPU cores/threads help?

This is a different batch, I've crunched a couple of them without any problems.

That's sure!

No.

Thanks, makes it more likely that it's a bad batch.
Does anything else about these task grab you as being odd; extra-large amounts of system RAM or GDDR5, memory controller load...?

I had this one the previous two days:
ala_structure_551-NOELIA_sh2forces-0-5-RND0004_0

it validated but run time was 119,668.62 while cpu time was 107,060.00.

Output:
Stderr output

<core_client_version>7.0.28</core_client_version>
<![CDATA[
<stderr_txt>
MDIO: cannot open file "restart.coor"
# Time per step (avg over 2000000 steps): 59.854 ms
# Approximate elapsed time for entire WU: 119708.496 s
called boinc_finish

</stderr_txt>
]]>

I only noticed it was running because my cruncher was so quiet. I thought my GPU fan might have died. I checked EVGA Precision, GPU usage was 7%. I was already over 30 hours crunching the wu on my 570GTX so I let it finish.

I have picked up another one this morning. I'm a little over 1 hour in and at 3% complete with 7% GPU usage.

Memory controller load: 1-2%

That's far too low!
It suggests the task isn't using the GPU memory efficiently, and is probably doing something on the CPU slowly and not multi-threaded.
You could probably use process explorer to find out what.

I see it timed out on an NVIDIA GeForce 310M. It tried to run using cuda31 - No chance.

Not cool.

Same problem with this one :

http://www.gpugrid.net/workunit.php?wuid=3934567

5-7% gpu load. 2% memory controller load on GTX660Ti

I will abort it. But instructions from the scientist would help :-)

[edit] I got a second one, same problem. I'm moving to short queue until the question is solved of fixed.

After running one of these tasks for 24 hours straight, I had to abort it. Sorry. My gpu usage on a 670 was about 8-12%.

I just aborted a NOELIA, it was using 1-2% GPU. It took it over an hour to get to 2.120% progress.

Hi !
Same for me on a GTX690 ! More than 24 hours and still running !

http://www.gpugrid.net/result.php?resultid=6180059

This is the 3rd WU of this kind and I already cancelled previous 2 .

Any action from the author of this "snail" NOELIA batch ?

How can he be signaled ? Is he aware of this ?
