Cray Message Passing Toolkit (CMPT)

General information about CMPT.

Cray Message Passing ToolKit (CMPT) is a collection of message passing libraries to aid in parallel programming.

MPI is a widely used parallel programming model that establishes a practical, portable, efficient, and flexible standard for passing messages between ranks in parallel processes. Cray MPI is derived from Argonne National Laboratory MPICH and implements the MPI-3.1 standard as documented by the MPI Forum in MPI: A Message Passing Interface Standard, Version 3.1.

Support for MPI varies depending on system hardware. To see which functions and environment variables the system supports, check the intro_mpi(3) manpages.

MPIs other than cray-mpich may not work on systems with CPE installed.
