Abstract

A system called Network Distributed Global Memory simplifies parallel computing in a distributed-memory environment by allowing processors to be programmed as though they had shared memory. NDGM manages message passing; applications perform puts and gets to a virtual buffer. Porting a 3D fluid dynamics code to NDGM was much easier than writing an explicit message-passing version.
