MPL is a message passing library written in C++11 based on the Message Passing Interface (MPI) standard. Since the C++ API has been dropped from the MPI standard in version 3.0 it is the aim of MPL is to provide a modern C++ message passing library for high performance computing.

MPL will neither bring all functions of the C language MPI-API to C++ nor provide a direct mapping of the C API to some C++ functions and classes. Its focus is on the MPI core functions, ease of use, type safety, and elegance.

MPL is a header-only library. Just download the source and copy the mpl directory containing all header files to a place, where the compiler will find it, e.g., /usr/local/include. As MPL is built on MPI, an MPI implementation needs to be installed, e.g., Open MPI or MPICH.
