Fractal Layout
A multi-level nested data arrangement specific to Huawei Ascend AI Core hardware. It recursively sub-partitions matrix blocks according to Cube Core access patterns to maximize L0 cache bandwidth utilization. External data must undergo format conversion before use with this layout.
Timeline (last 90 days)
DeepGEMM-Ascend kernels move matrix tiles from global memory into L1 cache and then into L0 cache for computation, and use fractal layout indexing when loading into L1 cache.
Fractal layout is a multi-level nested data arrangement unique to Ascend AI Core, differing from the row-major or column-major linear layouts common on NVIDIA GPUs.
