Interface, send a message or MPI, a standard system of sending messages by which a group of academic researchers and industrial design. This interface on a wide range of computers, parallel implementation.

The Standard MPI the structure and application of a few procedural Constitution defines that to make the program parallel to that of the Send Message are used, it can be used. This procedure for a large number of users are not to be used and in addition it is the nature of the standard this procedure makes the software written with these procedures, the library, portability, high on the platforms have different.

implements several of the MPI is that, many of which are thoroughly tested and are sure. Many of which are free and even some without restrictions and agreements are not to be used. Implementation of MPI for different languages, including Fortran language, C, C, Java, etc. is available. Two implementations known to include Open MPI and MPICH.

library standard, such as MPI and PVM industry, the development of software for parallel to the boom has been building software for parallel and scalable it possible to have made.
