MPI_Wtick
Returns the resolution of MPI_Wtime
Synopsis
double MPI_Wtick(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.
