How to profile Message Passing Interface (MPI) applications with the Oracle Solaris Studio Performance Tools. Includes examples from the analysis of performance data and a discussion of supported MPI implementations.
MPI_Pcontrol(3) LAM/MPI MPI_Pcontrol(3)NAME
MPI_Pcontrol - Controls profiling
SYNOPSIS
#include <mpi.h>
int MPI_Pcontrol(int level, ...)
INPUT PARAMETERS
level - Profiling level
NOTES
This routine provides a common interface for profiling control. The interpretation of level and any other arguments is left to the profil-
ing library. LAM/MPI's implementation of this function is a no-op that always returns MPI_SUCCESS
.
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr
is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked
with the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
MORE INFORMATION
For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards. These
documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).

ACKNOWLEDGEMENTS
The LAM Team would like the thank the MPICH Team for the handy program to generate man pages ("doctext" from ftp://ftp.mcs.anl.gov/pub/sow-
ing/sowing.tar.gz ), the initial formatting, and some initial text for most of the MPI-1 man pages.
