目前有大量的MPI实现，每一个都强调高性能计算的不同方面，或者旨在解决特定的研究问题。其结果是大量不兼容的MPI实现，所有这些都需要单独安装，并且它们的组合为最终用户带来了重大的后勤挑战。基于先前的研究，并受到从LAM/MPI，LA-MPI，FT-MPI和PACX-MPI项目的代码库中获得的经验的影响，Open MPI是一个全新的，生产质量的MPI-2实现，基本上围绕组件概念。Open MPI提供了以前在MPI的开源，生产质量实现中不可用的新颖功能的独特组合。它的组件体系结构为第三方研究提供了一个稳定的平台，并支持独立软件附加组件的运行时组合。本文简要介绍了Open MPI的目标、设计和实现，以及它的点对点实现的性能结果。
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 MPIis an all-new, production-quality MPI-2 implementation that is fundamentally centered around component concepts. Open MPI provides a unique combination of novel features previously unavailable in an open-source, production-quality implementation of MPI. Its component architecture provides both a stable platform for third-party research as well as enabling the run-time composition of independent software add-ons. 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.
