Hi Rafal,
Please use I_MPI_MPD_TMPDIR env variable - it has higher priority.
$ export I_MPI_MPD_TMPDIR=/tmp
and all temp files will be in /tmp directory.
Please don't use directories located on parallel file systems (like pvfs) for temporary files!
Regards!

Hi Dmitry, 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... Thanks for tip! Regards
Rafal, is it possible to create /tmp directory on a shared drive?
Regards!
Dmitry
$TMPDIR question
Hello, I've got simple question about TMPDIR behaviour of Intel MPI. We are receiving some info in the logs:
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. Is that right? How can we avoid it?
