mbarrier_arrive_expect_tx_relaxed

def mbarrier_arrive_expect_tx_relaxed[type: AnyType, scope: Scope = Scope.BLOCK, space: Scope = Scope.BLOCK](addr: Pointer[type, address_space=AddressSpace.SHARED], tx_count: Int32) -> UInt64

Configure a shared memory barrier to expect additional async transactions.

Updates the current phase of the memory barrier to track completion of additional asynchronous transactions. Only supported on NVIDIA GPUs.

Parameters:

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

Args:

• ​addr (Pointer[type, address_space=AddressSpace.SHARED]): Pointer to the shared memory barrier.
• ​tx_count (Int32): Number of expected transactions to track.

Returns:

UInt64: The state.
