MPI is a standard for communication among a group of distributed (or local) processes. It includes routines to send and receive data, communicate collectively, and other more complex tasks. The standard provides an API for C and Fortran, but bindings to various other languages also exist.Are you looking to become a quilting expert? Look no further than Missouri Star Quilt Tutorials.
