}

One required cold-path device transform from source checkpoint components into final execution-weight components.

The first supported producer preserves official E4M3 bytes, converts the BF16 inverse-scale grid into Marlin’s grouped F16 scale ABI, and repacks one logical matrix at a time. matrices_per_output == 2 represents the routed gate/up fusion [E, 2, N, K] -> [E, 2N, K]; all other projections use one.

Implementations

impl StaticWeightTransformPlan

pub fn source_component_ids(&self) -> [&WeightId; 2]

pub fn execution_component_ids(&self) -> [&WeightId; 2]

pub fn logical_dimensions(&self) -> &[u64]

pub fn execution_dimensions(&self) -> &[u64]

Matrix dimensions consumed by the native execution kernel after any explicitly typed cold-path padding. Block-FP8 transforms are exact; GPT-OSS MXFP4 may zero-extend only K to a supported Marlin tile.

pub const fn matrices_per_output(&self) -> u32

pub fn scratch_bytes(&self) -> Result<u64, VNextError>

Device scratch is shared across transforms and sized for the largest single fused output matrix, never for the model or expert count.
