I've got simple question about TMPDIR behaviour of Intel MPI.
We are receiving some info in the logs:
[bash]mpd: wn29_60522 (run 1652): Warning: the directory pointed by TMPDIR (/tmp/pbs.16445.mgmt1) does not exist!
/tmp will be used.[/bash]
We are using PBS Professional which sets TMPDIR to job-specific directory but it only creates it on the first compute node. I believe that this is a problem - I assume that mpd tries to use $TMPDIR on every node it runs.
I wanted to use $TMPDIR assigned by PBS because it is destroyed every time job finishes - that would look after cleaning up (in case if mpd failed and left some files behind) but as I see there is no "right" way...
I'm aware that /tmp should be local, have no fear :)
I see the best option is to clear /tmp on regular basis...
