Many MIMD message-passing multiprocessors are large-scale, but the programming environment based on message-passing and the limited memory on each node preclude many applications. Shared-memory multiprocessors do not have these restrictions, but it is very difficult to build large-scale ones. This research is to investigate the methods of building shared virtual memory systems on large-scale multiprocessors without shared memory, allowing parallel programs based on shared- memory model to run on these large-scale multiprocessors. The research provides the framework upon which to implement systems and programming languages based on shared-memory model that effectively harness the resources of large-scale stock multiprocessors.

许多MIMD消息传递多处理器都是大规模的，但基于消息传递的编程环境和每个节点上有限的内存排除了许多应用。共享内存多处理器没有这些限制，但要构建大规模的多处理器是非常困难的。本研究旨在研究在没有共享内存的大规模多处理器上构建共享虚拟内存系统的方法，使基于共享内存模型的并行程序能够在这些大规模多处理器上运行。该研究为基于共享内存模型的系统和编程语言的实现提供了框架，从而有效地利用了大规模存量多处理器的资源。
