# SmoothQuant with CK Tile
|
|
|
|
This example demonstrates SmoothQuant, a quantization technique for transformer models, using the CK Tile programming model. SmoothQuant enables efficient int8 inference by scaling activations and weights to balance quantization error.

|
## Algorithm and Math
|
|
|
|
Given input $X$ and per-channel scale $S$:
|
|
1. **Scale**: $Y_{i,j} = X_{i,j} \cdot S_j$
|
|
2. **Rowwise Dynamic Quantization**:
|
|
- For each row, $s = \max(|Y|) / 127$
|
|
- $Q_{i,j} = \text{round}(Y_{i,j} / s)$, $Q_{i,j} \in \text{int8}$
|
|
|
|
**Output**:
|
|
- Quantized tensor $Q$ (int8)
|
|
- Per-row scale $s$ (fp32)
|
|

## Tile Programming Model
|
|
|
|
- **Tiles**: Each thread block processes a tile (row or block).
|
|
- **Pipeline**: Modular, can be extended for further fusion.

## Build & Run
|
|
|
|
```bash
|
|
mkdir build && cd build
|
|
sh ../script/cmake-ck-dev.sh ../ <arch> # you can replace this <arch> to gfx90a, gfx942...
|
|
make tile_smoothquant -j`nproc`
|
|
```
|
|
This will result in an executable `build/bin/tile_smoothquant`
|
|
|
