摘要

设计和开发了一个快速消息传递库FMPL，通过利用诸如远程内存操作之类的通用架构通信支持来最大化通信性能，并通过消除动态通信开销和重叠通信和计算来最大化总性能。FMPL提供了低成本的通用点对点通信和集体通信，如广播、屏障同步和减少。在日立SR8000上，FMPL实现了12.8µs的8字节延迟。，而MPI达到20µs。FMPL是为构建功能更强大的消息传递库(如BLACS)以及需要最大性能的应用程序而设计的。

Design and Implementation of FMPL, a Fast Message-Passing Library for Remote Memory Operations

A fast message-passing library FMPL has been designed and developed to maximize communication performance by utilizing general architectural communication support such as remote memory operations, as well as to maximize total performance by eliminating dynamic communication overhead and overlapping communication and computation. FMPL provides a low-cost general-purpose point-to-point communication and collective communication such as broadcast, barrier synchronization and reduction. On a Hitachi SR8000, FMPL achieves an 8-byte latency of 12.8µsec., while MPI achieves 20µsec. FMPL is designed for building more highly functional message-passing libraries like BLACS as well as applications that need maximum performance.
