Execute the Expert Parallelism combine kernel.
Sends expert-processed output tokens back to their original devices asynchronously, without waiting for the transfers to complete.
Parameters:
- combine_dtype (
DType):DTypeused for the token payload during the combine phase (inferred). - hidden_size (
Int): Size of the model's hidden dimension (inferred). - top_k (
Int): Number of experts each token is routed to (inferred). - n_experts (
Int): Total number of experts across all GPUs (inferred). - max_token_per_rank (
Int): Maximum number of tokens per GPU (inferred). - n_gpus_per_node (
Int): Number of GPUs per node (inferred). - n_nodes (
Int): Number of physical nodes (inferred). - target (
StringSlice[ImmStaticOrigin]): Compile-time device target.
Args:
- atomic_counters (
ManagedTensorSlice[IOSpec[_, _].MutableInput, static_spec=atomic_counters.static_spec]): Atomic counters coordinating work across thread blocks during the combine phase. - input_tokens (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=input_tokens.static_spec]): Expert output tokens to send back to their original devices. Shape[num_tokens, hidden_size]. - src_info (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=src_info.static_spec]): Source routing information from the dispatch phase recording the originating rank and token index for each token. Shape[num_tokens, 2]. - send_ptrs (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=send_ptrs.static_spec]): Send buffer pointers for the combine phase. - recv_ptrs (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=recv_ptrs.static_spec]): Receive buffer pointers for the combine phase. - recv_count_ptrs (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=recv_count_ptrs.static_spec]): Receive count buffer pointers tracking the number of tokens received per expert. - context (
DeviceContext): GPU device context for the current device.
