[Swift-devel] swift pbs/beagle broken

Sun Nov 13 15:52:58 CST 2011

Its starting to look like some kind of aprun-based failure. I see this from more detailed logging I put into the generated script:

IN .submit script
aprun: Unexpected close of the apsys control connection
aprun: Exiting due to errors. Application aborted
aprun rc 1

I was led off track by the fact that the exitcode file is missing. Seems that its generated but then removed before we can see it. I suspect one part of the provider thinks the worker-launch job succeeded, and hence removes the exitcode file, but another part realizes that the job failed.  (conjecture...)

Now that that part is partially explained, I think I can go back to debugging this from manual qsubs which should go faster.

Im still unsure if the missing stdout/err files is due to a Beagle issue; starting to look more like maybe due to the weird way in which the aprun dies.

Digging deeper...
