cp_async_bulk_shared_cluster_global
def cp_async_bulk_shared_cluster_global[dst_type: AnyType, src_type: AnyType, mbr_type: AnyType, /, *, eviction_policy: CacheEviction = CacheEviction.EVICT_NORMAL](dst_mem: Pointer[dst_type, address_space=AddressSpace.SHARED], src_mem: Pointer[src_type, address_space=src_mem.address_space], size: Int32, mem_bar: Pointer[mbr_type, address_space=AddressSpace.SHARED])
Initiates an asynchronous bulk copy from global memory to shared CTA memory.
Performs a non-blocking copy of size bytes from global memory to shared
memory using the cp.async.bulk PTX instruction. Completion is signaled
via the mbarrier specified by mem_bar.
Both dst_mem and src_mem must be 16-byte aligned, and size must be a
multiple of 16. Requires sm_100 or higher.
Parameters:
- dst_type (
AnyType): The element type of the destination shared memory. - src_type (
AnyType): The element type of the source global memory. - mbr_type (
AnyType): The element type of the mbarrier object in shared memory. - eviction_policy (
CacheEviction): Cache eviction policy for the L2 cache. Defaults toEVICT_NORMAL.
Args:
- dst_mem (
Pointer[dst_type, address_space=AddressSpace.SHARED]): Destination pointer in shared CTA memory (16-byte aligned). - src_mem (
Pointer[src_type, address_space=src_mem.address_space]): Source pointer in global or generic memory (16-byte aligned). - size (
Int32): Number of bytes to copy (must be a multiple of 16). - mem_bar (
Pointer[mbr_type, address_space=AddressSpace.SHARED]): Pointer to the mbarrier object in shared memory used to signal completion.
