NAME

       MPI_Wtime -  Returns an elapsed time on the calling processor

SYNOPSIS

       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_WTIME .

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