Hello Benton,
  Thanks for your notice.

  But I am a novice for the parallel computation, I often use Fortran to compile my program, now I want to use the Parallel, can you give me some help how to begin?
  PS: I learned about OPEN MPI is the choice for my question solution. am I right?

best wishes to you & good luck
yours alex

Version 1.4.5 can be downloaded from the main Open MPI web site or any of its mirrors (mirrors will be updating shortly).
