Message 72010 - Posted: 8 Jan 2014 | 11:50:49 UTC

Hello

I am running the following WU's on 2 separate computers and noticed the 'remaining' time jumped from 200 hrs to >300 hrs. Is this normal?

The WU's are:

Been running for 35.5 hrs
http://www.primegrid.com/workunit.php?wuid=375539116
(my computer did blue screen on mea few times, so I down clocked my CPU from 5ghz to 4.8ghz as well as my gpu and it seems to be ok. Never had this happen until trying PrimeGrid)

Been running for 4.5hrs
http://www.primegrid.com/workunit.php?wuid=375539716

I am new to PrimeGrid and noticed the stallion challenge and wanted to participate. Does not appear they will be reported on time for me to do so, but I will allow them to continue if there is not an issue.

Thank you

Hello

I am running the following WU's on 2 separate computers and noticed the 'remaining' time jumped from 200 hrs to >300 hrs. Is this normal?


If the times you're talking about are the times being reported by the BOINC client, then yes, that's normal because those numbers are meaningless. For an accurate time estimate, please look in the stderr.txt file in the appropriate BOINC slot directory.

(my computer did blue screen on mea few times, so I down clocked my CPU from 5ghz to 4.8ghz as well as my gpu and it seems to be ok. Never had this happen until trying PrimeGrid)


If the computer is overclocked to the point where a BSOD happened, one has to wonder whether the calculations are ok. A few dropped bits here and there won't necessarily crash the computer, but will completely destroy the calculation. Since your computer has crashed several times, do you think it's worth finishing the calculation? The task may already be invalid; there's no way of knowing. It might be better to abort the tasks, back WAY off the overclocking, and start over. (PrimeGrid is a torture test compared to most other projects. The computer is driven harder, runs hotter, and is more likely to fail on our LLR and Genefer apps.)


I am new to PrimeGrid and noticed the stallion challenge and wanted to participate. Does not appear they will be reported on time for me to do so, but I will allow them to continue if there is not an issue.

Thank you


Chances are the estimates are way off, and you'll have no trouble with time limits. However, the validity of the results is in doubt since you seem to be overclocked too high. In the stderr.txt file, if you are seeing "MaxErr exceeded" messages, it means your computer is experiencing hardware failures due to overclocking.

Thank you Michael,

I checked the stderr.txt file and there was no sign of the message "MaxErr exceeded".

My curiosity wants to keep the WU going, but I would rather contribute something productive. Should I also abort the other WU's that were running at the same time?

I am down clocking my CPU and GPU for PrimeGrid.

Thank you again

Thank you Michael,

I checked the stderr.txt file and there was no sign of the message "MaxErr exceeded".

My curiosity wants to keep the WU going, but I would rather contribute something productive. Should I also abort the other WU's that were running at the same time?

I am down clocking my CPU and GPU for PrimeGrid.

Thank you again


I can't advise you on whether to proceed or to abort the tasks. I've seen them work and I've seen them fail. It's your choice.

As for the log you posted, there's nothing unusual in there.
