Expand description

Shared across every decoder layer of one loaded K3 model.

Fields§

§config: ModelConfig§graph: K3Graph§kda: KdaConfig§mla: MlaConfig§moe: LatentMoeConfig§output_res_proj: DenseWeight§output_res_norm: DenseWeight§output_res_proj_meta: (WeightDtype, usize)§output_res_norm_meta: (WeightDtype, usize)§output_host: OnceLock<(Vec<f32>, Vec<f32>)>§kda_kernels: OnceLock<K3KdaDecodeKernels>

Resolved once per loaded model. LinearAttention decode launches these.

§mla_kernels: OnceLock<K3MlaDecodeKernels>

Resolved once per loaded model. FullAttention decode launches these unless K3_CUDA_MLA=0.

§moe_kernels: OnceLock<K3MoeGemmKernels>

Resolved once per loaded model. Packed LatentMoE launches these.

§attnres: Mutex<HashMap<DevicePtr, AttnResStream>>

AttnRes is per-token across layers. Keyed by this step’s residual pointer so prefill (layer-outer, token-inner) still sees the same stream as CPU forward_token (token-outer, layer-inner).
