Personally, I didn't like Peter Pacheco's book all that much, so I'd like to add a couple more books to this list of recommendations: Using MPI: Portable Parallel Programming with the Message-Passing Interface, 2nd Edition William Gropp, Ewing Lusk, and Anthony Skjellum Copyright 1997, MIT Press http://www.mcs.anl.gov/research/projects/mpi/usingmpi/ Using MPI-2: Advanced Features of the Message-Passing Interface William Gropp, Ewing Lusk, Rajeev Thakur Copyright 1997, MIT Press http://www.mcs.anl.gov/research/projects/mpi/usingmpi2/index.html The second book covers the more advanced features of MPI-2. As a n00b just learning MPI, you probably don't need to learn that stuff until you've mastered the material in the first book I listed, or Pacheco's book. -- Prentice
