Contemporary improvement of workstation and network brings development of high-performance workstation cluster system. Viewing from the aspect of cost-performance of a system, a present workstation cluster system can provide better system than a multi-processor system. Therefore,improvement of techniques for high-performance workstation cluster is important problem today. We have developed Memory Based Communication Facility(MBCF) as a next generation network architecture and proved using the MBCF at a workstation cluster provides high performance cluster computing. The MBCF provides secure logical address to logical address copying in a user-mode with commodity network and hardware. It provides many functions other than simple remote write/read. Memory Based Fifo (MBFifo) is function of the MBCF for providing queue service on user memory space. Memory Based Signal(MBSignal) is function of the MBCF for executing function on remote host. In this thesis,we describe Remote Procedure Call (RPC) implemented on the MBFifo and MBSignal and evaluated performance of it. RPC is popularly used as a basic function of modern network computing system and a typical application of client-server model. RPC/MBFifo and RPC/MBSignal provides high performance RPC service with good semantics. Demonstrated performance of RPC/MBFifo and RPC/MBSignal are twice as high as that of RPC/UDP,RPC/TCP at round-trip latency.
