High Performance Protocols for Clusters of Commodity Workstations

P. Melas and E. J. Zaluska

Abstract
Over the last few years technological advances in microprocessor andnetwork technology have improved the performance achieved in clustersof commodity workstations dramatically. Despite those impressive improvementsthe cost of communication processing is still high. Traditional layeredstructured network protocols fail to achieve high throughputs becausethey access data several times. Network protocols which avoid therouting through the kernel can remove this limit on communicationperformance and support very high transmission speeds which are comparableto the proprietary interconnection found in Massively Parallel Processors.
