MPI - Message Passing Interface
Explore the Message Passing Interface (MPI), its history, programming model, and benefits. Understand how MPI enables portable and standardized parallel programming across distributed and hybrid HPC platforms. Gain knowledge about MPI libraries, usage, and setup in HPC environments.
We'll cover the following...
The Message Passing Interface (MPI) is a standardized and portable message-passing system that defines the syntax and semantics of a core of library routines useful to a wide range of users writing portable message-passing programs in C, C++, and Fortran.
History
Before the 1990’s, writing parallel applications for different computing architectures was a difficult and tedious task. At that time, many libraries could facilitate building parallel applications, but there was not a standard accepted way of doing it. A small group of researchers started discussions in Austria and came out with a Workshop on ...
