What is MPI?

MPI (Message Passing Interface) is a standardized and portable message-passing system designed to function on a wide variety of parallel computing architectures. It defines a set of functions and protocols that allow parallel programs to communicate and synchronize their execution. It's commonly used for developing high-performance computing applications, especially in scientific and engineering domains, where tasks are distributed across multiple processors or nodes in a cluster.
