I'll add that salloc will revoke the allocation as soon as its executable program terminates. If your program 1grabslurm starts background processes and exits, those background processes could persist after the 1grabslurm program terminates and the job allocation has been revoked. ________________________________________ From: [email protected] [[email protected]] On Behalf Of Gerrit Renker [[email protected]] Sent: Saturday, March 05, 2011 2:10 AM To: [email protected] Cc: [email protected] Subject: Re: [slurm-dev] Running Salloc From Bash Fails Under 2.2.3?
I just tried something similar under v2.3 pre3 (whose salloc is almost identical with that of 2.2.3) and it worked. Looking at your output it seems that the allocation (#38) is revoked immediately after it was granted, which could happen if the script '1grabslurm' exits very soon. I can not see a problem with the script below, but there may well be something that needs to be checked in the '1grabslurm' script -- please send more information, you can also send this privately. Alternatively, since it seems that salloc is used to generate an allocation, you could consider the --no-shell mode.
