A barrier is a synchronization object blocking a thread until a previous
defined number of threads have reached this barrier.
create_barriercreate_barrierCreateBarriercreate_barrierCreateBarrierCreateBarrier allocates and initializes the barrier object returned
in BarrierHandleBarrierHandleBarrierHandleBarrierHandleBarrierHandlebarrierHandle according to the attributes specified in
AttribNameAttribNameAttribNameAttribNameAttribNameattribName and AttribValueAttribValueAttribValueAttribValueAttribValueattribValue.
AttribNameAttribNameAttribNameAttribNameAttribNameattribName specifies the attribute class and AttribValueAttribValueAttribValueAttribValueAttribValueattribValue
the kind of the barrier. The description beneath lists all barrier kinds
supported by following parameter classes:
- ''""""""""""
empty string sets the default attributes.
- 'type'"type""type""type""type""type"
-
specifies what happens if a thread waits at a barrier:
- 'sleep'"sleep""sleep""sleep""sleep""sleep"
simply suspends the calling thread (default).
- 'spin'"spin""spin""spin""spin""spin"
a fast barrier implementation for short waits
that waits busy.
The TeamSizeTeamSizeTeamSizeTeamSizeTeamSizeteamSize argument specifies the number of threads that must
call wait_barrierwait_barrierWaitBarrierwait_barrierWaitBarrierWaitBarrier before any of them successfully return from
waiting. The value hold in TeamSizeTeamSizeTeamSizeTeamSizeTeamSizeteamSize must be greater than zero.
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
