Cluster system is one of the hot spots in the research area of high performance computer , while system area network ( san ) that used to connect nodes is considered to be the key point in the cluster system the aims of this paper are to study dedicated high performance san network based on distributed shared memory architecture , and set up cluster system with high price performance ratio the main work and originalities in this paper list as followings : 1 群机系统是高性能计算机研究领域的热点之一,而用于连接群机系统内部结点的系统域网络( san )是群机系统研究的关键。本文在分布共享存储器结构的基础上研究高性能专用san网络,构建高性能/价格比的群机系统。本文的主要工作和创新点如下: 1
Distributed Shared Memory (DSM), in Computer Architecture is a form of memory architecture where the (physically separate) memories can be addressed as one (logically shared) address space. Here, the term shared does not mean that there is a single centralized memory but shared essentially means that the address space is shared (same physical address on two processors refers to the same location in memory).
