Don't know if that helps you, but remember that SGE created a temporary directory (something like /tmp/#JOB_NO.#TASK_NO.QUEUE). Available to submitted scripts as $TMPDIR. I believe it even cleans it up automatically once a job finished.

What I've done is mount a 'scratch' partition as /tmp on all cluster nodes & people use $TMPDIR in their scripts.

Hi all, is there a way to use the scratch area  (local disk) on the
compute node in a transparent way from the submitted script point of
view?
What I want to do is to copy to and from the compute node scratch area
the job data using the prolog/epilog but I need also to start the
submitted script in the scratch area instead of the cwd.
Is there a way?
Thanks
Stefano
