Thanks Marcus, that works.

Though, ahem, SLURM/SchedMD, if you're listening, would it hurt to cover this in the documentation regarding prolog/epilog, and maybe give an example?


Just a thought,

Hi Erik,

the output of task-prolog is sourced/evaluated (not really sure, how) in 
the job environment.

Thus you don't have to export a variable in task-prolog, but echo the 
export, e.g.

echo export TMPDIR=/scratch/$SLURM_JOB_ID

The variable will then be set in job environment.
