On the Implementation and Evaluation of Berkeley Sockets on Maestro2 cluster computing environment

The support on cluster environments of ”legacy proto-cols ” is important to avoid rewriting the code of applica-tions, but this support should not prevent to achieve the maximum communication performance. This paper ad-dresses this issue by implementing the Berkeley sockets in-terface over the MMP message passing protocol, which is the lower layer of the Maestro2 cluster communication net-work. Experimental results show that MMP-Sockets offers a minimum latency of 25s and a maximum throughput of 1250Mbps. These values correspond to a relative increase of 80 % for the latency and a decrease of about 30 % for the throughput, regarding to a communication based only on MMP. However, MMP-Sockets increases the compatibility and portability of developed applications. 1
