Open MPI

Open MPI is an open-source implementation of the Message Passing Interface (MPI) standard, which is a widely used communication protocol for parallel programming on distributed computing systems. Open MPI provides a standardized and portable interface for developing parallel applications that can run on a wide range of computer architectures, from small clusters to large supercomputers. It supports a variety of communication mechanisms, including TCP/IP, shared memory, and high-speed network interconnects, and it provides a range of features and tools for debugging and optimizing parallel applications. Open MPI is widely used in scientific computing, engineering, and other fields where large-scale parallel processing is required.
