📚 Modern CUDA Learn Notes with PyTorch for Beginners: It includes Tensor/CUDA Cores, TF32/F16/BF16/F8, 📖150+ CUDA Kernels🔥🔥 with PyTorch bindings, 📖30+ LLM/VLM🔥, 📖40+ CV/C++...🔥, 📖50+ CUDA/CuTe...🔥 Blogs and 📖toy-hgemm library🔥🔥 which can achieve the performance of cuBLAS, check 📖HGEMM Supported Matrix👇 for more details. Welcome to 🌟👆🏻star this repo to support me, many thanks ~ 🎉🎉
Currently, on NVIDIA L20, RTX 4090 and RTX 3080 Laptop, compared with cuBLAS's default Tensor Cores math algorithm CUBLAS_GEMM_DEFAULT_TENSOR_OP, the HGEMM (WMMA/MMA) implemented in this repo (blue🔵) can achieve 99%~100%+ of its (orange🟠) performance. Please check toy-hgemm library🔥🔥 for more details.

}📖 150+ CUDA Kernels 🔥🔥 (面试常考题目) (©️back👆🏻)
Workflow: custom CUDA kernel impl -> PyTorch Python bindings -> Run tests. 👉TIPS: * = Tensor Cores(WMMA/MMA), otherwise, CUDA Cores; / = not supported; ✔️ = supported; ❔ = in my plan.
