NAME

       MPI_Wtime -  Returns an elapsed time on the calling processor

SYNOPSIS

       #include <mpi.h>
       double MPI_Wtime(void)

RETURN VALUE

       Time in seconds since an arbitrary time in the past.

NOTES

       This  is  intended  to  be  a  high-resolution, elapsed (or wall) clock.  See MPI_Wtick to
       determine the resolution of MPI_Wime .  If the attribute  MPI_WTIME_IS_GLOBAL  is  defined
       and true, then the value is synchronized across all processes in MPI_COMM_WORLD .

NOTES FOR FORTRAN

       This function is declared as DOUBLE PRECISION MPI_WTIME() in Fortran.

       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/sowing/sowing.tar.gz  ),  the   initial
       formatting, and some initial text for most of the MPI-1 man pages.
