Groups

Every TNF probe for MPI is associated with the mpi_api group, so choosing that group allows Prism to probe all the MPI routines for which probes exist (including the I/O routines). Additional groups exist to probe subsets of the MPI routines, as well. Some routines are associated with more than one group. The ten groups for MPI routine probes are these:

• mpi_api - All the TNF probes for MPI routines

• mpi_blkp2p - Probes for blocking point-to-point routines

• mpi_coll - Probes for collective routines

• mpi_comm - Probes for communicator-related routines

• mpi_datatypes - Probes for data type-related routines

• mpi_nblkp2p - Probes for nonblocking point-to-point routines

• mpi_procmgmt - Probes for process-management routines

• mpi_pt2pt - Probes for all point-to-point routines (blocking and nonblocking)

• mpi_request - Probes for functions producing or acting on request(s)

• mpi_topo - Probes for topology-related routines
