【摘要】 计算机网络技术正广泛应用于工业信息管理及自动化控制等领域。网络的核心是资源共享。为了更有效地使用共享资源 ,需要缓解网络冲突。分布式共享内存是解决这些问题的一个较好的方案。分布式系统是一个出现在独立作为单机系统的用户计算机的采集〔1〕,用硬件来处理 ,机器是独立的 ;用软件来处理 ,是一个单机系统。软件在分布式系统中起着重要作用 ,系统软件设计方法主要由操作系统软件来决定 ,多CPU计算机系统可分为两类 :有共享存储的和设有共享存储的。共享内存机器 (多处理系统 )较容易编程 ,但不易创建 ;设有共享内存的机器 (多计算机系统 )则编程较难而创建比较容易。分布式共享内存技术用模拟共享内存的方式使多计算机系统更容易编程更多还原

【Abstract】 Computer network technology is widely used in oil exploration equipment. The one of network is resource sharing. In order to use the sharing resources more effectively, it is necessary to solve network confliction. Distributed memory sharing is a good method to solve these problems. A distributed system appears to the acquisition of users computer as a single computer. To deal with hardware, the machine is autonomous, and to deal with software, the machine is a single computer, it plays an important role in distributed system. The design method of system softwqre is largely determined by the operation system. Multiple CPU computer systems fall into two categories: those that have shared memory and those that do not. The shared memory machines (multiprocessors)are easier to program but harder to build, whereas the machines without shared memory (multicomputers)are harder to program but easier to build. Distributed shared memory technique can make the multicomputers easier to program by the method of simulating shared memory.更多还原
