Abstract:
TEG is a new methodology for point-to-point messaging
developed as a part of the Open MPI project. Initial performance
measurements are presented, showing comparable ping-pong latencies in
a single NIC configuration, but with bandwidths up to 30% higher than
that achieved by other leading MPI implementations. Homogeneous
dual-NIC configurations further improved performance, but the
heterogeneous case requires continued investigation.
Presented: Euro PVM/MPI 2004, September, 2004, in Budapest, Hungary.
