67 Abs tract As hardw are and softw are technologies have been developed, computer environments have rapidly been changed. T here are many researches in the field of parallel processing about clustering; substituting cheap PCs and w orkstations for super computers by interconnecting high speed netw orks to them. How ever, cluster systems, w hich are constructed in SAN (System Area Netw ork), have problems in the entire performance of systems using complicated protocols like T CP/IP. As the result of that, a lot of researches for reducing the softw are overhead of T CP/IP and for high- speed netw orking are underw ay. And VIA (Virtual Interface Architecture) protocol is the one of protocols that are made to reduce the overhead. In this paper, We implement parallel libraries, MPI(Message Passing Interface) and BSP(Bulk Synchronous Parallel) libraries, for effective parallel programming on the VIA based cluster systems and analyze them through comparing w ith MPI and BSP libraries w hich are implemented in T CP/IP or UDP/IP based environment.
