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.
