* To expedite the transition to Slurm, use the moab2slurm utility to convert Moab msub job scripts to the Slurm sbatch equivalents. See the moab2slurm man page on any TOSS 3 machine for details.
** On Flux only systems, there is a slurm2flux utility to convert Slurm sbatch job scripts to the flux batch equivalents.
