Abstract:
In this paper we make the case for adding standard non-blocking
collective operations to the MPI standard. The non-blocking
point-to-point and blocking collective operations currently defined
by MPI provide important performance and abstraction benefits. To
allow these benefits to be simultaneously realized, we present an
application programming interface for non-blocking collective
operations in MPI. Microbenchmark and application-based performance
results demonstrate that non-blocking collective operations offer
not only improved convenience, but improved performance as well,
when compared to manual use of threads with blocking collectives.
