Open MPI is an open source implementation of the MPI specification, widely used and adopted by the research community as well as industry. The Open MPI library is jointly developed and maintained by a consortium of academic institutions, national labs and industrial partners. It is installed on virtually all large-scale computer systems in the US as well as in the rest of the world. The goal of this project is to enhance and modernize the Open MPI library in the context of the ongoing evolution of modern computer systems, and to ensure its future operability on all upcoming architectures. We aim at implementing fundamental software techniques that can be used in many-core systems to execute MPI-based parallel applications more efficiently, and to tolerate process and memory failures at all scales, from current systems, up to the extreme scales expected before the end of the decade.<br><br><br>

Open MPI 是消息传递接口（Message Passing Interface，MPI）规范的开源实现，被学术科研界与工业界广泛使用与采纳。

Open MPI 库由学术机构、国家实验室及产业合作伙伴组成的联盟联合开发并维护，几乎部署于美国乃至全球所有的大型计算机系统中。

本项目的目标是在现代计算机系统持续演进的背景下，对 Open MPI 库进行升级与现代化改造，并确保其在未来所有新型架构上均可正常运行。

我们旨在研发可适配众核系统的基础软件技术，以更高效地执行基于 MPI 的并行应用程序，并在从当前系统直至本十年末预计的超大规模场景下，实现全尺度的进程与内存故障容错。
