This tool gathers its results from the ranks (to rank 0) for recording for posterity. The call used for this gather is MPI_Gather (several instances). Would it be more logical to use PMPI_Gather so that these calls are not included by this profiling tool (future expanded version) or another profiling tool in a profile of the application? That may well be an unrealistic scenario but if it occurred woul d there not be infinitely recursive MPI_Gather calls triggered?
