tem_getAveTimerVal Function

public function tem_getAveTimerVal(me, timerHandle, comm, nProcs) result(retValue)

Get the average of timer durations across all partitions.

Note

This assumes the same timerhandle to be used across all partitions for all timers.

Arguments

Type IntentOptional Attributes Name
type(tem_timer_type), intent(inout), optional :: me

timer object
integer, intent(in) :: timerHandle

timer handle
integer, intent(in) :: comm

communicator handle
integer, intent(in) :: nProcs

Number of processes in the communicator.

Return Value real(kind=rk)

timer value
