Mojo function

umma_arrive_peer_cta

umma_arrive_peer_cta[type: AnyType](mbar_ptr: UnsafePointer[type, mbar_ptr.origin, address_space=AddressSpace.SHARED])

Signal arrival at the barrier on the peer CTA of the pair.

This is the mirror of umma_arrive_leader_cta. Where the leader variant clears bit 24 of the SMEM address to target the leader CTA's barrier, this function sets bit 24 to target the peer CTA's barrier within the same cluster. Used when the leader CTA needs to signal a CTA-private barrier on its partner.

Parameters:

• ​type (AnyType): The type of the memory barrier.

Args:

• ​mbar_ptr (UnsafePointer): Pointer to the shared memory barrier.
