NYU ultracomputer-designing an MIMD shared memory parallel computer
Journal Article
·
· IEEE Trans. Comput.; (United States)
The design for the NYU ultracomputer, a shared-memory MIMD parallel machine composed of thousands of autonomous processing elements is presented. This machine uses an enhanced message switching network with the geometry of an omega-network to to approximate the ideal behaviour of Schwartz's paracomputer model of computation and to implement efficiently the important fetch-and-add synchronisation primitive. The hardware which would be required to build a 4096 processor system using 1990's technology is outlined. System software issues are also discussed and analytic studies of the network performance are presented. Finally, a sample of efforts to implement and simulate parallel variants of important scientific programs is included. 45 references.
