[slurm-users] Slurm prolog export variable

[Yap, Mike]

Hi All

Can anyone assist the following

We're using Bright Cluster 9.1 with CentOS 7.9 running with slurm 2.02.6
We have a script running on prolog exporting the SCRATCH as variable for user running job
Addition command on the script to create a user folder accordingly

When submitting the job, the folder is created without any error on the compute node (which indicate the prolog is being executed without an issue) but $SCRATCH seems to be undone once the prolog script is done
We also tried to create an additional script to only export SCRATCH but no luck
We have been using the same script for an older setup and it work fine. Any suggestion if there is any workaround to define $SCRACTH beside getting user to define it in their submit script ?

Prolog script
#!/bin/sh
export SCRATCH=/scratch/$SLURM_JOB_USER/$SLURM_JOB_ID
mkdir --parents $SCRATCH

Thanks
Mike
