MPIrelated

MPIrelated is a term used in documentation and knowledge bases to denote topics related to the Message Passing Interface (MPI). It serves as a category or tag for content that deals with MPI standards, implementations, and usage in parallel computing.

MPI is a standardized API for writing parallel programs that run across multiple processes, usually on distributed memory systems. It provides routines for point-to-point and collective communication, synchronization, and derived datatypes, enabling scalable execution on clusters and supercomputers.

Content labeled MPIrelated covers the evolution of the MPI standard (MPI-1, MPI-2, MPI-3, MPI-4), popular implementations such as Open MPI, MPICH, Intel MPI, and MVAPICH, and programming concepts including communicators, ranks, datatypes, requests, and topologies. It also includes advanced features like non-blocking communication and one-sided communication (RMA).

Practical MPIrelated topics include building and running MPI programs, debugging, profiling and performance tuning, and environment configuration. Tools commonly discussed include various MPI implementations, performance profilers, and debuggers.

The aim of MPIrelated content is to provide neutral, concise information for developers using MPI and for readers seeking to understand how message passing enables scalable parallel computation.
