并行计算就是在并行计算机或分布式计算机等高性能计算系统上所作的超 级计

算，其物质基础是高性能并行计算机 （ 包括分布式网络计算机）。 本章首先从当代科学与工程问题的计算需求出发，先简单地讨论并行计算与计算科学；然后讨论并行计算机系统的互连，包括静态互连网络、动态互连网络和标准互连网络；最后讨论并 行 计 算 机 的 系 统 结 构 模 型、并行计算机的存储访问模型以及并行计算机的存储组织 （ 层次存储技术和高速缓存一致性问题 ） -Parallel computing is done on a parallel computer or distributed computers and other high-performance computing systems supercomputer

Count, which is the material basis for high-performance parallel computers (including distributed network computer). This chapter begins　the computing needs of contemporary science and engineering problems starting, first briefly discuss parallel computing and computational science　and then discuss the parallel computer system interconnection, including static interconnection networks, dynamic interconnection networks and standard interconnection network　final discussion parallel computer architecture model, storage access model of parallel computers and parallel computer storage organization (hierarchical storage technology and cache coherency problem)
