Where can I find an OpenMP or MPI tutorial online?

OpenMP

Two excellent OpenMP tutorials are available online:

• An OpenMP tutorial from Lawrence Livermore National Laboratory (LLNL): https://computing.llnl.gov/tutorials/openMP/
• An OpenMP tutorial from the National Energy Research Scientific Computing Center (NERSC): http://www.nersc.gov/nusers/help/tutorials/openmp/?PHPSESSID=5087fda194a557a0e2c7705d75692d0e

You can find the latest OpenMP specifications at:

MPI

Three good introductions to MPI are available online:

• An MPI tutorial prepared by Indiana University's High Performance Applications team: http://rc.uits.iu.edu/hpa/mpi_tutorial/index.shtml
• A tutorial from a course on high performance data management and processing at IU: http://beige.ucs.indiana.edu/I590/node52.html
• LLNL's introduction to MPI: https://computing.llnl.gov/tutorials/mpi/

LLNL also has a more advanced article covering MPI performance topics:

At IU, more information is available at the High Performance Applications team's MPI support page.
