Message Passing Interface

What Does Message Passing Interface Mean?

Message Passing Interface (MPI) is a system that aims to provide a portable and efficient standard for message passing. It is widely used for message passing programs, as it defines useful syntax for routines and libraries in different computer programming languages such as Fortran, C, C++ and Java.


Techopedia Explains Message Passing Interface

Message Passing Interface is portable and flexible, and was essentially developed by researchers for academia and industrial purposes to work on networks of different parallel computers. Implementations of MPI have been created by various developers and are available for free on the Internet. MPI has helped in networking and parallel computing on an industrial and global scale, and helped improve the working of large-scale parallel computer applications. Basic design goals of using MPI include portability, flexibility and efficiency.

Message Passing Interface is not an IEEE or IOS standard, but in fact an industrial standard for writing message-passing programs on high-performance computing platforms.
