Hi Erik, We use a private fork of https://github.com/hpc2n/spank-private-tmp
It has worked quite well for us - jobs (or steps) don’t share a /tmp and during the prolog all files created for the job/step are deleted. Users absolutely cannot see each others temporary files so there’s no issue even if they happen to have a hard corded path ie: /tmp/myfiles.txt -Greg On 12 May 2020, at 18:40, Ellestad, Erik <erik.elles...@ucsf.edu<mailto:erik.elles...@ucsf.edu>> wrote: I was wanted to set TMPDIR from /tmp to a per job directory I create in local /scratch/$SLURM_JOB_ID (for example) This bug suggests I should be able to do this in a task-prolog. https://bugs.schedmd.com/show_bug.cgi?id=2664 However adding the following to task-prolog doesn’t seem to affect the variables the job script is running with. unset TMPDIR export TMPDIR=/scratch/$SLURM_JOB_ID It does work if it is done in the job script, rather than the task-prolog. Am I missing something? Erik -- Erik Ellestad Wynton Cluster SysAdmin UCSF
