[slurm-users] --partition requests ignored in scripts

[Bunis, Dan]

Thanks so much for this answer!  Turned out that default partitions get set on this HPC via an environment variable, so armed with the knowledge you shared, I've been able to figure out a viable path for my use-case by making use of 'unset SBATCH_PARTITION' =)

My suspicion is that there is an environment variable SBATCH_PARTITION
set in your shells.  Such a variable will override the #SBATCH directive,
but not the command line switch.

>From man sbatch:

INPUT ENVIRONMENT VARIABLES
[...]
    NOTE: Environment variables will override any options set in a batch
    script, and command line options will override any environment
    variables.
