RREETTUURRNN VVAALLUUEE
       Time in seconds of resolution of MPIWtime.


DESCRIPTION
       MPIWtick  returns  the resolution of MPIWtime 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 MPIWtick should be 10^-3.


NNOOTTEE
       This  function does not return an error value. Consequently, the result
       of calling it before MPIInit or after MPIFinalize is undefined.
