ABSTRACT
InfiniBand host channel adapters (HCAs) with PCI Express achieve 20 to 30 percent lower latency for small messages compared with HCAs using 64-bit, 133-MHz PCI-X interfaces. PCI Express also improves performance at the MPI level, achieving a latency of 4.1 ?s for small messages. It can also improve MPI collective communication and bandwidth-bound MPI application performance.
