| * Each job script template is intended for a program using multiple processor cores/threads on one or more nodes. Each variant should be used with Open MPI or another MPI library that is tightly-integrated with Slurm. | * Each job script template is intended for a program using multiple processor cores/threads on one or more nodes.

| * Sections of each script that can/should be edited are delimited by a ''[EDIT]'' tag. All Slurm job options are denoted by a line that starts with ''#SBATCH'' followed by flags that would otherwise be passed on the command line. Slurm job options can easily be disabled in a script by inserting a space in the prefix, e.g. ''# SLURM'' and reenabled by deleting that space. | * Sections of each script that can/should be edited are delimited by a ''[EDIT]'' tag.
