Interconnection Networks for Parallel and Distributed Processing: An Overview

CURRENT integrated circuit technology is making feasible computer systems consisting of hundreds or thousands of processors. One of the most difficult problems in the design of large-scale parallel and distributed computer systems is the choice of a communications network. An efficient method is needed for linking the system's processors, memories, and other devices to each other. As can be observed from the papers in this Special Issue, there are many different approaches to the solution of this problem. The best "solution" for a particular system is a function of the system's intended applications, size, speed requirements, cost constraints, etc.
