JPPS Abstract

Parallel Computing on the Berkeley NOW

Appeared in JPPS '97

The UC Berkeley Network of Workstations (NOW) project demonstrates a new approach to large-scale system design enabled by technology advances that provide inexpensive, low latency, high bandwidth, scalable interconnection networks. This paper provides an overview of the hardware and software architecture of NOW and reports on the performance obtained at each layer of the system; Active Messages, MPI message passing, and benchmark parallel applications.
