Real-Time Extensions to the Message-Passing Interface (MPI)

This article describes the ongoing work of real-time message passing interface (MPI) standardization. Real-time MPI (MPI/RT) provides a consistent set of extensions and, in some cases, restrictions to the high-performance computing Message Passing Interface Standard, emphasizing changes that enable and support real-time communication and are supportable on embedded and other real-time systems.
