triton.experimental.gluon.language.amd.cdna5.mbarrier.arrive(mbarrier, *, count=1, _semantic=None)

Arrive at an mbarrier with a specified count.

The operation requires a count attribute of at least 1, and decreases the pending arrival count of the mbarrier by the specific count. If the pending count reaches zero, the phase changes (is decremented in a wraparound manner) and the pending count is reloaded with the init count value. Returns the mbarrier’s phase parity (0 for even, 1 for odd) prior to the arrive operation.

Parameters:

• mbarrier (shared_memory_descriptor) – Barrier to be signalled.

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

Returns:

Phase of the mbarrier prior to the arrive operation.

Return type:

int
