The performance of a PC cluster system is limited by the use of traditional communication protocols, such as TCP/IP because these protocols are accompanied with significant software overheads. To overcome the problem, systems based on user-level interface for message passing without intervention of kernel have been developed. The VIA(Virtual Interface Architecture) is one of the representative user-level interfaces which provide low latency and high bandwidth. In this paper, a VIA system is implemented on an SCI(Scalable Coherent Interface) network based PC cluster. The system provides both message-passing and shared-memory programming environments and shows the maximum bandwidth of 84MB/s and the latency of . The system also shows better performance in comparison with other comparable computer systems in carrying out parallel benchmark programs.
