Protocols and Software for Exploiting Myrinet Clusters

Abstract : A cluster, by opposition to a parallel computer, is a set of separate workstations interconnected by a high-speed network. The per- formances one can get on a cluster heavily depend on the performances of the lowest communication layers. In this paper we present a software suite for achieving high-performance communications on a Myrinet-based cluster: BIP, BIP-SMP and MPI-BIP. The software suite supports single- processor (Intel PC and Digital Alpha) and multi-processor machines, as well as any combination of the two architectures. Additionally, the Web-CM software for cluster management that cover job submissions and node monitoring is presented as the high-level of the software suite. \textcopyright Springer-Verlag Berlin Heidelberg 2001.
