tem_timeControl_globalTriggered Function

  1. tem_timeControl_module.f90
  2. tem_timeControl_module
  3. tem_timeControl_globalTriggered

public function tem_timeControl_globalTriggered(me, now, comm) result(hasTriggered)

This routine checks globally if the control has triggered.

It takes care of communication as well. A reduction of the trigger status might be needed, depending on the time definitions in the trigger. This communication is done with the MPI communicator comm, and all processes calling this routine should be members of comm. The communication is only done, if necessary. If the trigger became active since the last check or update, the triggered argument will be set to true. If delay_check is true, the communication is done with a nonblocking allreduce, which performs the check essentially on the previous check interval, rather than the current one.

If this should be done in combination with other status communications to avoid unnecessary synchronisation points, the separate routines tem_timeControl_triggered and tem_timeControl_update have to be used instead.

Arguments

TypeIntentOptionalAttributesName
type(tem_timeControl_type), intent(inout) :: me

Time control to check if it was triggered across all processes.
type(tem_time_type), intent(in) :: now

Current time to use for the comparison.
integer, intent(in) :: comm

Communicator to use for the global reduction.

Return Value logical

Result indicating if the time control has triggered.
