Xgrid is a batch scheduler... while MPI is an API for parallel

You can writing an MPI program, and submit it to XGrid. XGrid will find
the requested number of machines for you, and then start the job.

On the other hand, you can install SGE (GridEngine) on a Linux cluster
-- SGE is more powerful than XGrid -- and let it schedule your serial
or parallel jobs.
