This is a domain-specific language designed for writing high-performance GPU/CPU/NPU operators. Built on top of the TVM compiler, it lets developers achieve highly optimized implementations of operators such as GEMM and FlashAttention without hand-writing low-level code. It supports multiple hardware backends, including NVIDIA CUDA, AMD ROCm, Apple Metal, and Huawei Ascend, and comes with built-in auto-tuning and debugging visualization tools, plus example operators for large models such as DeepSeek MLA.
