High Performance Computing with Harness over InfiniBand

Abstract

Harness is an adaptable and plug-in-based middleware framework able to support distributed parallel computing. By now, it is based on the Ethernet protocol which cannot guarantee high performance throughput and Real Time (determinism) performance. During last years, both the research and industry environments have developed both new network architectures (InfiniBand, Myrinet, iWARP, etc.) to avoid those limits. This paper concerns the integration between Harness and InfiniBand focusing on two solutions: IP over InfiniBand (IPoIB) and Socket Direct Protocol (SDP) technology. Those allow Harness middleware to take advantage of the enhanced features provided by InfiniBand Architecture. © 2009 IEEE.
