A C++20 Interface for MPI 4.0

Authors: Ali Can Demiralp, Philipp Martin, Niko Sakic, Marcel Krüger, and Tim Gerrits (RWTH Aachen University)

Abstract: We present a modern C++20 interface for MPI 4.0. The interface utilizes recent language features to ease development of MPI applications. An aggregate reflection system enables generation of MPI data types from user-defined classes automatically. Immediate and persistent operations are mapped to futures, which can be chained to describe sequential asynchronous operations and task graphs in a concise way. This work introduces the prominent features of the interface with examples. We further measure its performance overhead with respect to the raw C interface.
