Abstract

DIMMnet-1 is a high-performance network interface for a PC cluster system. It uses memory bus for IO bus to relax a bottleneck of networks. Moreover, a PC memory bus is spread bandwidth earliest in a PC, the DIMMnet-1 can reorganize a NIC according to spreading bandwidth of a communication link. However, the NIC that use a parallel transmission lacks a scalability of a bandwidth of a communication link. To resolve this problem, we developed new NICs : DIMMnet-1/bDais and DIMMnet-2. We employ a high-speed serial transmission on these NICs. Therefore we have to expand the DIMMnet network protocol. Now we have been developing new DIMMnet network protocol by two parts. The One is the CoreLogic which includes communication primitives. In this paper, we describe the rest of that which is the InfiniSWIF that includes functions of packet forwarding. And we propose the Concurrent Datagram communication service which is implemented in the InfiniSWIF and gives reliability and scalability for the DIMMnet network protocol.
