Optimal Communication Performance on Fast Ethernet with GAMMA

Abstract. The current prototype of the Genoa Active Message MAchine GAMMA is a low-overhead, Active Messages-based inter-process communication layer implemented mainly at kernel level in the Linux Operating System. It runs on a pool of low-cost Pentium-based Personal Computers PCs networked by a low-cost 100base-TX Ethernet hub to form a low-cost message-passing parallel platform. In this paper we describe in detail how GAMMA could achieve unprecedented communication performance less than 13 s one-way user-to-user latency time and up to 98 of the communication throughput of the raw interconnection hardware on such a kind of low-cost parallel architecture.
