[slurm-users] How to request for the allocation of scratch .

[navin srivastava]

Any suggestion on the above query.need help to understand it.
Does TmpFS=/scratch   and the request is #SBATCH --tmp=500GB  then it will
reserve the 500GB from scratch.
let me know if my assumption is correct?

Regards
Navin.
