MPI

MPI (Message Passing Interface) is a standard describing how to pass messages between programs running on the same or different machines.

The functionality provided by MPI implementations is very much like PVM. However, since MPI is a formal standard it is being actively supported by all major vendors, PVM is not. Some vendors have highly-optimized MPI libraries available on their systems. There are also a couple of public implementations of the MPI standard, such as MPICH and LAM / MPI. The ADF package supports a number of vendor versions of MPI (for SGI, HP, IBM), and MPICH and LAM / MPI.

If you wish to use the MPI version of the ADF package you should determine if one of the standard versions of MPI is already available for you, or if you need to install it yourself.
