In the (recent) past I had tasks, that ran from 4 to 12 hours, also depending on the type of CPU.
Now I have a number of tasks that will run for a week or more. Is this new?
And will the amount of credit be adjusted accordingly?

Regards, Ruud

I am having the same problem. CPU tasks typically take 6 - 10 hours to complete, using 3 threads

Starting this morning:
- I canceled one task that was less than 1 % complete after 2+ hours
- I canceled a second task that was 5% complete after 6 hours

Something has changed!!!!

Same here. Elderly computer and normal running is about 10 hours.
One unit cancelled after 5% in 10 hours; current unit at 90% after 44 hours.
Ruud - don't expect more credits: the 6,836.19 (where on earth did such a figure come from?!) seems to be hard-wired in the software.

I've had some rogue very long GPU tasks as well so it's just not CPU ony.

And yeah...if it takes that much longer to tune then it should pay that much more as well!

This unit still "running" after 65 hours. In truth it hasn't moved an inch from yesterday. Big waste of computer time and will now be given the chop.

Message 1632 - Posted: 6 Nov 2022, 22:56:25 UTC - in response to Message 1627.  

What I was afraid of, happened today: one of the tasks - https://sech.me/boinc/Amicable/workunit.php?wuid=22422555 - exceeded its deadline and the task was given to another machine, which finished it in a flash.
That will probably mean, that I won't get any credit after I finished the task. It is running for 130h now, and will need another day.

I have a total of 7 tasks, which will run from 6 to 8 days, and will certainly finish after the deadline.
I will keep the above mentioned task running, and let it finish to see what happens.
The other tasks have been put on hold.

The recent problem of long-running units appears to have ended after a week or so, with units now completing satisfactorily. My "average work done" figure has taken a hit but is gradually recovering.

The above mentioned task has finished, and has been marked: Completed, too late to validate.
OK, that was to be expected. Next I aborted all tasks that I had put on hold.
Earlier I mentioned 7, but it turned out to be 12 tasks.
Lost about 1000 hours of processing time; not very nice.

I looked at the aborted tasks, and the ones that have been processed by a wingman and granted credit, all have run on a GPU.
So, that does not seem to be a problem.

Things look to be good now, as Sygopet mentioned.
What we have to do now, is keep a close eye on these tasks, and watch progress and time remaining.

There really is something wrong with these tasks (at least if run on a CPU, they seem to run fine on a GPU).

Today I aborted a number of tasks that did not show much progress (<1%) after more than an hour.

Right now I am at my computer(s), and noticed one task starts, progress goes to 0.288%, and sits there, even after 13 minutes.
While I am watching this, I see a task on the same system, that runs for about 7 hours, and progress is at about 65%, suddenly fall back to 0.212% and keeps sitting there. Very weird.
Time to abort these too.

Hi all,

same to me running CPU tasks with 8 cores and in 1,5 days running only 14%, aborted
again, another CPU task with same 8 cores and don't know how many hours and only 2%, aborted.
today another unit with 8 cores 19 hours and only 16%

really don't know what to say because computer is an AMD Ryzen 7 3870X with 32 GB DDR4 RAM and SSD.
before I've been crunching units in less than 1.5 hours

Today I had a GPU task that ran for 12 hours, and at the moment I have another one almost running for 5 hours / 65% completion...

I have nothing else running on my mac, before this the tasks were taking between 30mn and 1h to complete.

Anyone else experiencing the same ?

Yes. I run on two machines and have had tasks taking ten times longer than usual.

I had another one than ran 7 hours and then it went down again, very variable though, maybe "globally longer" than before but I should compile data to confirm this feeling.

Bloody hell I just found out I got another one that took 21 hours to complete, the other cruncher who got it took less than half the time to perform (but still it was 8 hours run).

Most of the tasks take from 40mn to 1h20 I would say, with some "peak" tasks around 2 hours from time to time, I only got 3 very long ones in the past week : 12h, 7h and now 21h.

Needless to say my RAC is falling down the black hole...

I commented regarding this issue before, it's not the first time the project goes through slow search ranges. The positive side of this is we're finding a lot of new amicable pairs now (more than 4000 new pairs today).

OK thanks for the feedback, happy to see it is not an issue and it is helping the project !

Hopefully then I do find some of these pairs, because as credit is concerned a 21 hours task awards the same as a 30mn task...

Duration suddenly dropped from 10-20mn now.

We should call this project yoyo :D

Same observation. My task typically takes 70 minutes to complete. Starting yesterday, a task is at 10% after 1 hour, but the estimated time grown to 2d plus as the progress is only 0.001% every several seconds.

Running on intel 11th gen i5 with hyper threading. I just turned off HT to see if that makes any diff.
