Abstract
As network computing become commonplace, the
interconnection networks and the communication system
software become critical in achieving high performance.
Thus, it is essential to systematically assess the features
and performance of the new networks. Recently, Myricom
has introduced a two-port "E-card" Myrinet/PCI-X
interface. In this paper, we present the basic performance
of its GM2.1 messaging layer, as well as a set of
microbenchmarks designed to assess the quality of MPI
implementation on top of GM. These microbenchmarks
measure the latency, bandwidth, intra-node performance,
computation/communication overlap, parameters of the
LogP model, buffer reuse impact, different traffic
