triton.experimental.gluon.language.nvidia.hopper.mbarrier.arrive(mbarrier, *, count=1, pred=True, from_cta=None, _semantic=None)

Arrive at an mbarrier with a specified count.

Parameters:

• mbarrier (shared_memory_descriptor) – Barrier to be signalled.

• count (int) – Count to arrive with. Defaults to 1.

• pred (bool) – Scalar predicate. Operation is skipped if predicate is False. Defaults to True.

• from_cta (int, optional) – Mask of CTA-ID bits preserved when routing the arrival, in [0, num_ctas - 1]. Defaults to num_ctas - 1, which arrives from each CTA to itself; 0 routes from CTA 0 to every CTA.
