Additional Reading Materials


Message Passing Systems.

The PVM home page.


The MPI home page.
This is the best place to get info on MPI from, including implementations and the MPI forum itself.

The implementation that you should use, that is installed on the TORC (Tennessee Oak Ridge Cluster) cluster is MPICH .
A duplex postscript version of the MPI 1.1 API (with thanks to the LAM team) is available. There is also a version of MPI developed here at UTK which has the ability to recover from faults. See: http://icl.cs.utk.edu/ft-mpi/
