-# Add + Rmsnorm2D + rowwise dynamic quantization forward
+# Add + RMSNorm2D + Rowwise Dynamic Quantization (RDQuant) with CK Tile

-This folder contains example for add + Rmsnorm2D + rowwise dynamic quantization forward using ck_tile tile-programming implementation. Rdquant is short for rowwise dynamic quantization here.
+This example demonstrates a fused kernel for elementwise addition, 2D RMSNorm, and rowwise dynamic quantization using the CK Tile programming model. This pattern is common in LLMs for efficient normalization and quantized inference.

-## build
-```
+---
+
+## Algorithm and Math
+
+Given input $X$ and residual $R$:
+1. **Elementwise Add**: $Z = X + R$
+2. **RMSNorm**: $\text{rms}(Z) = \sqrt{\frac{1}{N} \sum_{i=1}^N Z_i^2 + \epsilon}$, $Y_i = \frac{Z_i}{\text{rms}(Z)} \cdot \gamma_i$
+3. **Rowwise Dynamic Quantization**:
+   - For each row, $s = \max(|Y|) / 127$
+   - $Q_i = \text{round}(Y_i / s)$, $Q_i \in \text{int8}$
+
+**Output**:  
+- Quantized tensor $Q$ (int8)
+- Per-row scale $s$ (fp32)
+
+---
+
+## Tile Programming Model
+
+- **Tiles**: Each thread block processes a tile (row or block).
+- **Tile Engine**: Loads tiles, performs add, RMSNorm, and quantization.
+- **Pipeline**: Modular, can be extended for further fusion.
