LSF is the scheduler that manages job submissions to the GHPCC system. Documentation is available via the man pages. Try 'man bsub' for submission related commands and 'man jobs' for status queries.
Jobs can be submitted using the 'bsub' command, generally followed by command line options or a submission script redirected to stdin. A full listing of command line options can be found in the man pages ('man bsub').
Detailed guidelines for submitting various types of jobs can be found at http://wiki.umassrc.org/wiki/index.php/Submitting_Cluster_Jobs
Several queues are available on the GHPCC, with details at http://wiki.umassrc.org/wiki/index.php/Queue_Descriptions.
