Very slow CEP WU

Hello there!
I am currently running a CEP WU. It has taken 26 hours of CPU time, and it is at 7.4%. It is not stuck, it is progressing at a very slow but steady rate. Estimated time to completion (per BOINC) is 57 more hours, and the estimate keeps increasing. My typical times for other WUs are 5-7 hours for a Help Conquer Cancer WU. I have no problem letting my current CEP WU run to completion, but should I do that, or is it wasting time?

Many thanks in advance!

Re: Very slow CEP WU

If the progress is calculated as linear, it's going to take 351 hours or 14.93 days. Suspect it's going to time out on pre-programmed flops or on general time out. So, first, check the quorum if the other result has returned and how long it took.

For what I can see the current B type jobs have a factor 20 time out of current average expected flops (bound / est):

<rsc_fpops_est>79878358574728.000000</rsc_fpops_est>
<rsc_fpops_bound>1597567171494560.000000</rsc_fpops_bound>

If it thus came in and the Time To Complete before start was projected e.g. as 20 hours, theory is that it would bounce at 400 hours, but if not a serious loss.

Also check if your CPU is running maximum cycles and not somehow took a easter holiday and running at throttled down power. OR, check if another process is eating time.

let us know.

Re: Very slow CEP WU

Thanks for the suggestion to check the result status. It is unit E000489_264B_00292i00c, and as I can see one result has been returned, claiming 277 hours. It is in the order of magnitude of what you predicted, given that perhaps my laptop is a bit slower than the computer that ran this WU. As I may need to travel with the laptop (off time for BOINC) the unit may bounce, but I guess I should leave it running and if it bounces, no great loss.
Thanks!

Re: Very slow CEP WU

The follow-up question is: Why did it take you 250 hours or more to start the job, when the deadline is 12 days.

This smells like the next copy is going out sometime today or tomorrow as your result is going to be considered "No Reply". If the extra copy is returned quicker than yours I'm not so sure what credit will be given under current policy.

At any rate, once overdue, your message log is going to warnings and suggestions to abort.

Re: Very slow CEP WU

Perhaps other copies have already timed out, and barbanis' copy is a replacement.

With the shorter deadline, there is a strong chance the replacement will time out, too.
