This paper presents the design of the communication inter face called RWAPI over the Myrinet-2000 interconnect for clusters of PCs. RWAPI has been developed to provide per formance to higher applications on a wide variety of archi tectures. We implemented RWAPI using the GRWA archi tecture and evaluated the communication performance. We obtained a very low latency and a throughput close to the maximum user bandwidth for messages as small as 32 kB.
