mpiP: a lightweight profiling library for MPI applications.
mpiP is a lightweight profiling library for MPI applications. Because
it only collects statistical information about MPI functions, mpiP
generates considerably less overhead and much less data than tracing
tools. All the information captured by mpiP is task-local. It only
uses communication during report generation, typically at the end of
the experiment, to merge results from all of the tasks into one output
