MPI_Wtick(3OpenMPI)					   MPI_Wtick(3OpenMPI)

NAME
       MPI_Wtick - Returns the resolution of MPI_Wtime.

SYNTAX
C Syntax
       #include <mpi.h>
       double MPI_Wtick()

Fortran Syntax
       INCLUDE 'mpif.h'
       DOUBLE PRECISION MPI_WTICK()

C++ Syntax
       #include <mpi.h>
       double Wtick()

RETURN VALUE
       Time in seconds of resolution of MPI_Wtime.

DESCRIPTION
       MPI_Wtick  returns  the resolution of MPI_Wtime in seconds. That is, it
       returns, as a double-precision value, the  number  of  seconds  between
       successive clock ticks. For example, if the clock is implemented by the
       hardware as a counter that is incremented every millisecond, the	 value
       returned by MPI_Wtick should be 10^-3.

NOTE
       This  function does not return an error value. Consequently, the result
       of calling it before MPI_Init or after MPI_Finalize is undefined.

SEE ALSO
