The Message Passing Interface (MPI) is a library specification for
message-passing. It is a standard API (Application
Programming Interface) that can be used to create
parallel applications. The MPI
standardization effort makes use of the most attractive features of a number of
existing message passing systems, rather than selecting one of them and adopting
it as the standard.
Message Passing Interface Forum This location contains the official MPI (Message Passing Interface) standards documents, errata, and archives of the MPI Forum. The MPI Forum is an open group with representatives from many organizations that define and maintain the MPI standard.
