MPI_WTIME(3)							  MPI_WTIME(3)

NAME
     MPI_Wtime - Returns an elapsed time on the calling processor

SYNOPSIS
     C:

	  #include <mpi.h>

	  double MPI_Wtime()

     C++:

	  #include <mpi.h>

	  double Wtime()

     Fortran:

	  INCLUDE "mpif.h" (or USE MPI)

	  DOUBLE PRECISION TIME

	  TIME=MPI_WTIME()

STANDARDS
     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Wtime routine returns the elapsed wall-clock time in seconds
     since some time in the past on the calling processor.  This routine is
     intended to be a high-resolution, elapsed (or wall) clock.	 See
     MPI_Wtick(3) to determine the resolution of MPI_Wtime.

RETURN VALUES
     Floating-point elapsed time in seconds.   Note that calls made at the
     same time to MPI_Wtime() on different nodes running the same program may
     yield different values.  The time returned is not necessarily the elapsed
     wall-clock run-time of the calling process.

     If a program is checkpointed and restarted, values returned by
     MPI_Wtime(3) following the restart may be smaller than those returned
     before the checkpoint.
