ClassdescMP: Easy MPI programming in C++

TL;DR

ClassdescMP simplifies MPI programming in C++ by leveraging reflection to facilitate message construction, enhancing MPI's capabilities without hiding its core API, thus making parallel programming more accessible.

Contribution

It introduces a C++ library that uses reflection to ease message building in MPI, while preserving access to standard MPI functions for performance.

Findings

Simplifies MPI message construction in C++

Maintains full access to MPI API for performance optimization

Enhances ease of use without sacrificing MPI capabilities

Abstract

ClassdescMP is a distributed memory parallel programming system for use with C++ and MPI. It uses the Classdesc reflection system to ease the task of building complicated messages to be sent between processes. It doesn't hide the underlying MPI API, so it is an augmentation of MPI capabilities. Users can still call standard MPI function calls if needed for performance reasons.
