TNF Probes for MPI I/O

Like the MPI routines, each MPI I/O routine is associated with two TNF probes: one ending in _start, and one ending in _end. Probes are also included for some specific arguments, most of which are defined in the MPI standard and described in the man pages included with Sun MPI 4.0. The ctxt argument for the context id assigned to a particular communicator, however, is not mentioned in the standard or man pages. It is described in "TNF Probes for MPI".

Every TNF probe for MPI I/O is associated with both the mpi_api and the mpi_io groups. Choosing mpi_api allows Prism to probe all the MPI routines for which probes exist, whereas choosing mpi_io allows you to focus on the I/O routines. Additional groups exist to probe subsets of the I/O routines, as well. The seven groups for MPI I/O routine probes are these:

mpi_api - All the TNF probes for MPI routines

mpi_io - MPI I/O routines only

mpi_io_consistency - Atomicity and synchronization routines

mpi_io_datarep - Data representation routines

mpi_io_errhandler - Error-handling routines

mpi_io_file - Group(s), in addition to mpi_api and mpi_io

mpi_io_rw - Read/write routines
