Execute the Expert Parallelism async dispatch kernel. Tokens are transferred in either Blockwise FP8 or BF16 format.
Parameters:
- input_dtype (
DType):DTypeof the input tokens before dispatch (inferred). - dispatch_dtype (
DType):DTypeused for the quantized token payload during dispatch (inferred). - dispatch_scale_dtype (
DType):DTypeof the block scales accompanying the dispatched tokens (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). - dispatch_fmt_str (
StringSlice[ImmStaticOrigin]): String selecting the dispatch token format, either"BlockwiseFP8"or"BF16"(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 dispatch phase. - input_tokens (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=input_tokens.static_spec]): Input tokens to dispatch to experts. Shape[num_tokens, hidden_size]. - topk_ids (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=topk_ids.static_spec]): Top-k expert IDs per token. Shape[num_tokens, top_k]. - send_ptrs (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=send_ptrs.static_spec]): Send buffer pointers for the dispatch phase. - recv_ptrs (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=recv_ptrs.static_spec]): Receive buffer pointers for the dispatch phase. - recv_count_ptrs (
ManagedTensorSlice[IOSpec[_, _].Input, static_spec=recv_count_ptrs.static_spec]): Receive count buffer pointers tracking tokens received per expert. - context (
DeviceContext): GPU device context for the current device.
