摘　　要：开发分布共享存储系统的目的是为了在分布式存储器的基础上构造逻辑上的共享存储器模型，对于如何在共享存储器模型的基础上为用户进程构造虚拟空间，传统的分布共享系统并未给予足够的重视。只有在操作系统中把分布共享存储技术、存储器管理和文件系统结合起来，才能充分发挥分布共享存储技术具有的能力。基于以上思想，在文中提出了一个实现了分布共享存储的操作系统模型，并分析了该模型一个实现原型，讨论该原型具有的优缺点。通过在操作系统中取消进程的逻辑空间，使进程直接在文件上运行，该模型不仅能够实现分布共享存储，而且和许多传统操作系统以及传统分布共享存储系统相比，具有许多优点。该操作系统实现了分布共享存储技术和操作系统中的存储管理以及文件系统的完美结合。Traditional DSM systems have just implemented a shared memory model upon a physical distributed memory, they don't pay enough attention on how to construct process virtual address space upon these shared memory models. DSM technique can not be fully developed without integrating DSM with memory management and file system in operating system. this paper proposes an operating system model. discusses its implementation prototype, as well as its advantage and disadvantage. By abolishing process virtual address space and making processes run on files, not only has our scheme implemented DSM, but also has gained other advantages over traditional operating system and traditional DSM systems. The operating system has integrated DSM, memory management and file system perfectly.
