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.
