We have some resources for this. First, we have a tutorial showing various aspects of the using the SGE system. Also, more advanced users may want to use task arrays to process multiple job scripts. SGE also supports several multiprocessing paradigms. Even if you are not a programprogrammer, you may want to review this page so you will be familiar with the technologies. Then if you see that a program you do want to use supports a given technology, you'll be able to use that program correctly (because submitting a job which uses 8 processors when you only tell SGE it will use 1 can cause SGE to make bad decisions with regards to scheduling), and to yield the maximum amount of performance gain.
