摘要

本文介绍了一种基于PVM的软件虚拟共享内存GKD-VSM。为分布式内存环境提供了一种基于FORTRAN语言的共享内存并行编程模型。为了减少软件开销,GKD-VSM采用了几种方法,包括特殊用途的用户级多线程方案和同步点预取和后存储方案。给出了基本操作的延迟。

Implementing a software virtual shared memory on PVM
This paper introduces a software virtual shared memory, GKD-VSM on PVM. It provides a shared memory parallel programming model in FORTRAN language for distributed memory environments. To reduce the software overhead GKD-VSM takes several approaches, including special-purposed user-level multithread scheme and Prefetch&Poststore at synchronization points scheme. The latencies for basic operations are presented.
