With or without PE, SGE starts the parallel application, and that's
mostly all it does. SGE cannot change the scaling issues of your
parallel program.

However, there are 2 things that SGE can do a better job than a normal user:
1) SGE may be able to pick better machines, or better sets of machines
which have lower latency and/or higher bandwidth to communicate among

2) SGE can adjust the process priority dynamically.

As you said, when I using PE to run parallel programs, the SGE just allocate a set of machines which I've selected, then the post-working is functions of MPI, right? Furthermore, can I use PE to improve the parallel programs efficiency by using SGE? If I can, how?
