MPIprovided

MPIprovided is a library or framework that offers implementations of the Message Passing Interface (MPI) standard. MPI is a standardized and portable message-passing system designed to facilitate communication between processes in parallel computing environments. Libraries that are "MPIprovided" typically offer optimized versions of MPI functions, often tailored for specific hardware architectures or network interconnects. This can lead to improved performance for parallel applications that rely on MPI for inter-process communication.

These implementations are crucial for high-performance computing (HPC) clusters, supercomputers, and other distributed systems where tasks are divided among multiple processing units. By using an MPIprovided library, developers can write portable parallel code that can then be compiled and run efficiently on various MPI-compliant systems. The specific features and performance characteristics can vary significantly between different MPIprovided libraries, with some focusing on raw speed, others on advanced features, and some on broad compatibility. Examples of such implementations include Open MPI, MPICH, and Intel MPI. The choice of which MPIprovided library to use often depends on the target hardware and the specific performance requirements of the application.
