OpenMPI: High Performance Computing with MPI

OpenMPI is an open-source implementation of the Message Passing Interface (MPI) standard. MPI is a widely used standard for programming parallel computers, particularly in the high performance computing (HPC) community. OpenMPI provides a library of functions that enable communication between processes running on different nodes of a parallel computer. OpenMPI is compatible with a wide range of hardware and software platforms, making it a popular choice for HPC applications. It is also actively developed and maintained by a large community of users and developers.
