Emulating shared memory to simplify distributed-memory programming
John A. Clarke · IEEE Computational Science and Engineering · 1997
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.
