A parallel computing system and method having improved performance where a program is concurrently run on a plurality of nodes for reducing total processing time, each node having a processor, a memory, and a predetermined number of communication channels connected to the node and independently connected directly to other nodes. The present invention improves performance of performance of the parallel computing system by providing a system which can provide efficient communication between the processors and between the system and input and output devices. A method is also disclosed which can locate defective nodes with the computing system.
This invention relates to Computer-implemented methods of highly efficient parallel computing systems. The U.S. Government has rights in this invention pursuant to Contract No. DE-AC 04-76DP00789 between the Department of Energy and AT&T Technologies, Inc.
