Mojo function

init_clc_barriers

def init_clc_barriers[num_clc_stages: Int](clc_full_ptr: Pointer[SharedMemBarrier, MutUntrackedOrigin, address_space=AddressSpace.SHARED, _safe=False], clc_empty_ptr: Pointer[SharedMemBarrier, MutUntrackedOrigin, address_space=AddressSpace.SHARED, _safe=False], clc_producer_arv_count: Int32, clc_consumer_arv_count: Int32)

Initialize CLC full/empty barrier pairs.

Called inside the elect_one_warp && elect_one_thread guard for CLC-enabled kernels (default, block_scaled, blockwise_fp8, grouped_2sm).

Parameters:

num_clc_stages (Int): Number of CLC pipeline stages to initialize barriers for.

Args:

clc_full_ptr (Pointer[SharedMemBarrier, MutUntrackedOrigin, address_space=AddressSpace.SHARED, _safe=False]): Shared-memory pointer to the CLC full barriers, one per pipeline stage.
clc_empty_ptr (Pointer[SharedMemBarrier, MutUntrackedOrigin, address_space=AddressSpace.SHARED, _safe=False]): Shared-memory pointer to the CLC empty barriers, one per pipeline stage.
clc_producer_arv_count (Int32): Number of arrivals the producer makes on each CLC full barrier.
clc_consumer_arv_count (Int32): Number of arrivals the consumer makes on each CLC empty barrier.
