Message Passing Interface Forum

消息传递接口（MPI）是过去10年来科学并行应用社区使用的通信软件的事实标准。目前的标准有一个用于点对点和单边数据交换的核心例程，阻塞集体通信例程，远程并行文件访问和动态过程控制。此外，它还支持派生数据类型、通信上下文、进程组和虚拟进程拓扑等特性。然而，多核和异构芯片的到来给科学界带来了重大挑战，因为它们正在新的计算平台上移植和优化现有的应用程序。建议的消息传递接口论坛解决了继续关注于增强MPI的活动，用于在MIMD计算系统中的进程之间传递数据，用于并行远程文件操作和用于这种并行应用程序的动态过程控制。该论坛的工作将产生一个通信标准，适合于满足Peta-Scale级别及更高级别的下一代计算设施的应用需求

Message Passing Interface (MPI) is de-facto standard for communications software used by scientific parallel applications community well over last 10 years. The current standard has a core of routines used for point-to-point and one-sided data exchange, blocking collective communications routines, remote parallel file access and dynamic process control. In addition, it provides support for features such as derived data types, communications contexts, process groups, and virtual process topologies. However, arrival of multicore- and heterogeneous chips pose a significant challenge for scientific community as they are porting and optimizing existing applications on new computational platforms.The proposed Message Passing Interface Forum addresses the continuation of activity focused on enhancing the MPI for passing data between processes in a MIMD computing system, for parallel remote file operations and for dynamic process control of such parallel application programs. The work of this forum will produce a communications standard suitable for addressing the needs of applications on the next generation computing facilities at the Peta-Scale level and beyond
