    Abstract

    [Truncated] Most message passing parallel programs use regular logical process topologies to support their computation. For example, many parallel matrix computations are well suited to the logical torus topology, where processes can communicate with one another using logical constants such as SEND_TO_NORTH and BROADCAST_TO_ROW. As they define the relationship between processes, topologies present excellent debugging opportunities. Benefits include topology-consistent visualisations, automatic identification of misdirected messages, and the ability to logically relate events in different processes.
    However, topology support is inadequate in many environments, including the popular Message Passing Interface (MPI) standard. Programmers typically implement topology support themselves, increasing the likelihood of introducing errors. Moreover, there are currently no widely deployed debuggers for environments such as MPI that exploit topology information.
