[slurm-users] SLURM_TMPDIR

[Juergen Salk]

Hi Angelines,

we create a job specific scratch directory in the prolog script but
use the task_prolog script to set the environment variable.

In prolog:

scratch_dir=/your/path
/bin/mkdir -p ${scratch_dir}
/bin/chmod 700 ${scratch_dir}
/bin/chown ${SLURM_JOB_USER} ${scratch_dir}

In task_prolog:

scratch_dir=/your/path
echo "export TMPDIR=${scratch_dir}"

The fully qualified pathnames of the prolog and task prolog scripts 
need to be defined in slurm.conf, e.g.:

Prolog=/etc/slurm/prolog
TaskProlog=/etc/slurm/task_prolog

We also clean up job specific scratch directories in the epilog
script.

Best regards
Jürgen
