The developers of the slurm scheduling system (SchedMD) has extensive documentation on how to use the batch system. We recommend two documents in particular:

Slurm cheatsheet
Quickstart guide

NIH Biowulf

Also highly recommended, as Biowulf and FRCE are similar and have many software packages in common.
