Abstract
Recent versions of MPICH2 have featured Nemesis – a scalable, high-performance, multi-network communication subsystem. Nemesis provides a framework for developing Network Modules (Netmods) for interfacing the Nemesis subsystem to various high speed network protocols. Cray has developed a user-level Generic Network Interface (uGNI) for interfacing MPI implementations to the internal high speed network of Cray XE and follow-on computer systems. This paper describes the design of a uGNI Netmod for the MPICH2 nemesis subsystem. MPICH2 performance data on the Cray XE are presented.
