Hands-On with CK-Tile: Develop and Run Optimized GEMM on AMD GPUs
- 15 April 2025
Composable Kernel (CK-Tile) for ROCm is used to build portable high-performance kernels for accelerating computing, e.g. HPC, DL and LLMs for training and inference workloads. CK-Tile APIs consist of vendor optimized kernels like GEMM, BatchGemm, fused-MHA, fused-MoE, SmoothQuant, element-wise kernels and many other kernels. This blog focuses on creating the most commonly used GEMM kernel, incorporating a vendor-optimized kernel pipeline and policies, and covers key CK-Tile concepts for quick learning.
