Open MPI: A Flexible High Performance MPI

Category: Data Management, Desktops, Laptops and OS

Overview A large number of MPI implementations are currently available, each of which emphasize different aspects of high-performance computing or are intended to solve a specific research problem. The result is a myriad of incompatible MPI implementations, all of which require separate installation, and the combination of which present significant logistical challenges for end users. Building upon prior research, and influenced by experience gained from the code bases of the LAM/MPI, LA-MPI, FT-MPI, and PACX-MPI projects, Open MPI is an all-new, production-quality MPI-2 implementation that is fundamentally centered around component concepts. This paper presents a high-level overview the goals, design, and implementation of Open MPI, as well as performance results for it's point-to-point implementation.
