Message 38498 - Posted: 30 Mar 2019, 17:15:56 UTC

Hello,

i have 2 native tasks that doesn't end. Both tasks (# 220202844 and # 220201994) have a runtime of about 30 hours each by now. Normally the tasks finish in about 3 hours or less on my machine (ID: 10586067).

Shall i just abort them? I put them on hold right now in the BOINC Manager.

Thanks and regards,
djoser.

Multicore I guess?
You may continue the tasks.
Then open a console, cd to your BOINC directory and run the following command:
watch -n10 "find ./slots/ -name \"AthenaMP.log\" |sort |xargs -I {} -n1 sh -c \"egrep 'ISFG4SimSvc.*INFO.*Event nr. ' {} |tail -n1\""

The screen updates every 10 s.
After a while you should see some progress.

Hi computezrmle,

yes, you are guessing right, it's multicore (3 CPUs per task).
Thanks for the console command.
It shows clearly that there is no progress at all for the last 27 hours. The tasks are stuck.
Is there a way to shut native tasks down gracefully?

Yours, djoser.

No.
Restarting your BOINC client will start the tasks from the scratch.
Beside that, either let them run or cancel them.

Thanks for your help!
Even rebooting the machine didn't get the tasks back to work...
I just canceled them now and got me a fresh batch :-)

Greetings!
