Author Topic: Computation Error with CUDA (Read 19855 times)

Frizz · « **on:** 10 Aug 2010, 05:17:09 pm »

My GT 240 was running stable for weeks now. Suddenly I get a "Computation Error" for all my WUs. And every time after exactly the same amount of time: 03:43

I am using MB_6.08_CUDA_V12_VLARKill_FPLim2048.exe

Where can I get more information on the exact type of this "Computation Error". Are there logfiles I can look at?

Copy "client_state.xml" to desktop or somewhere else you like. In notepad searach for the word error. Look a few lines above and below for more descriptions of the problem.

and that bit is the error itself. the rest is a dump few people will be able to make sense of (much less go bughunting in)

haven't come across this one. one of the notorious -12 ?

Were thise work units moved from gpu to CPU???

No. Nothing rescheduled.

What I seriously don't understand is why the error happens AT THE EXACT SAME SECOND for all WUs!

<stderr_txt> setiathome_CUDA: Found 1 CUDA device(s): ... </stderr_txt>

Also, have a look just a couple of lines above <stderr.txt>. If Carola's right, you should see

<message>
 - exit code -12 (0xfffffff4)
</message>

and a few lines above that,

<exit_status>-12</exit_status>

If you see any other number, let us know: I must say, my first instinct on reading your initial report that they happened at the exact same second was that it might be a return of the -177s, but only you can tell until the servers are back up.

... uh right... there's such things as standard error messages

'exceeded maximum disk space' ? or a memory leak? modern systems rarely run out of space, but a quick check can't hurt. The other one - try rebooting perhaps? something stuck on the GPU?

If you see any other number, let us know: I must say, my first instinct on reading your initial report that they happened at the exact same second was that it might be a return of the -177s, but only you can tell until the servers are back up.

oh right, exit codes get parsed to somewhere else...
I was just guessing, Richard, as I assumed -12 would show up as such. I've yet to come across one for myself, so I don't know what they look like.
ah and max CPU time exceeded should be -177 from the description in the faq.

Whatever the exit code is, it'll be in there somewhere.

I knew I'd had a -12 on one machine since the servers went off, so those entries were a direct copy from client_state.

Others may appear slightly differently, but <exit_status>xxx</exit_status> will always be a key entry.

During past outages I have successfully search "client_state.xml" for the word "error". On those searches I successsfully located -12 errors and -177 errors.

My first reaction is that they are -177 since they all occured at the same instant during processing. That was also my experience with the -177 errors.

Damn it - just found some "Computation Error" for CPU units too. 5 WUs. All at the EXACT same time.
Is this an indication for -177 errors?

By the way: What exactly is this -177 error?

You need to be certain exactly what they are - search client_state, don't just rely on our speculation.

-177 errors arise from bad estimates issued by the server - they don't indicate a problem at your end. At this moment, I would guess they're re-issues for the ghost WUs which are timing out - look for _2, _3 or higher on the end of the task name. Don't worry about them unless you get a huge number - if you do, Fred's latest rescheduling tool can deal with them, by resetting the estimates.

OK found it (-177). It would be nice if the BOINC client would show this - and not just "Computation error". Especially at times when SETI is offline.

How can I prevent this -177 error?
