Message 41810 - Posted: 3 Mar 2020, 13:35:41 UTC - in response to Message 41800.  

So task 265306266 finished yesterday after about 80 hrs and I didn't spot any error messages in the log on the occasions that I checked it, up to events processed = about 99700. BOINC reports a success and assigns me 3k credits.
On the other hand, the final log reports
02:13:14 GMT +00:00 2020-02-28: cranky-0.0.31: [INFO] ===> [runRivet] Fri Feb 28 02:13:12 UTC 2020 [boinc PbPb heavyion-mb 2760 - - pythia8 8.235 default 100000 42]
22:02:19 GMT +00:00 2020-03-02: cranky-0.0.31: [INFO] Container 'runc' finished with status code 1.
not zero as usual, and the MC Plots page (updated "2020-03-03 14:02:35") has gone from showing
run events attempts success failure lost
PbPb heavyion-mb 2760 - - pythia8 8.235 default 0 10 0 6 4
to
run events attempts success failure lost
PbPb heavyion-mb 2760 - - pythia8 8.235 default 0 10 0 7 3
implying that it thinks the job failed. (OK, so that might not be my specific task.)

But, did those 80 CPU hours actually achieve anything useful, or not?

YES yours is Valid and Theory tasks are not a certain length of time so we have short ones and long ones.

I have had a few of those 3 day tasks in the past (testing the versions) and one thing about these Theory tasks is you can get one that runs for 10 days and then end as a Computer Error so I just abort them if they get to 5 days and still try running (BUT I always watch mine start running via the VM Console since you can see if it has any *Fail* problems right at the start and then you can watch for them on the last page to see if it is *Failed* and if that happens in either places it will run for days but end up a Computer Error.

This is how you want them to be on the VM Console after running

I understand that different tasks model different physics cases with different codes and so run for different times. My point is that what looks to me and to BOINC like a task that has successfully generated 100k lead-ion events, isn't reflected on the MC Plots page even several days later:
run events attempts success failure lost
PbPb heavyion-mb 2760 - - pythia8 8.235 default 0 10 0 7 3
I'm assuming that MC Plots represents the physics "customer" view, so either those 100k events aren't useful for physics, or else (N.B. attempt numbers 10 vs 42) the results take a long time to percolate through. In turn, wouldn't the latter mean that the status reported on MC Plots is meaningless for deciding whether or not to cull tasks locally, as implied in the Sherpa thread?

It is satisfying that the last Theory I will run for a while was also the longest I have ever had, at 3 days 17 hours 27 min 8 sec.

It was a pythia8, and I had looked for it on MCplots, but it was not there, so I just let it run.

It is a Theory_2378-1045515-2_2, hence can be found here:
http://mcplots-dev.cern.ch/production.php?view=runs&rev=2378&display=all

You may filter the complete list for:

attempts: 4
success: 2
failure: 0
unknown: 2

OK, I was searching in Run 2279, which must have been the last one I looked for.
