Reduction with CK Tile
This example demonstrates parallel reduction (sum, max, etc.) using the CK Tile programming model, a core operation for normalization, statistics, and aggregation in deep learning.
Algorithm and Math
Given a tensor X and a reduction axis, compute:
-
Sum:
Y = \sum_i X_i -
Max:
Y = \max_i X_i -
Mean:
Y = \frac{1}{N} \sum_i X_i -
Tilewise Reduction: Each thread block reduces a tile (block) of the input, using shared memory and register accumulation for efficiency.
Tile Programming Model
- Tiles: Each thread block processes a tile (block) of the input tensor.
- Pipeline: Modular, can be extended for fused reductions or post-processing.
