Inside NVIDIA’s cuDNN Graph API: Fusion, Autotuning, and Plan Reuse with cuDNN Frontend

MarkTechPost 4 weeks ago 26

The article presents a tutorial that builds cuDNN Frontend graph API examples that fuse convolution+bias+ReLU, then expands to autotuning across multiple engine configurations and plan handling. It validates numerical correctness by asserting the maximum error stays below 5e-2 versus a PyTorch reference. As a result, it shows how to benchmark fused execution and how shipping a preselected autotuned plan (or a serialized one) can outperform relying on cuDNN’s default engine pick for fixed “hot” shapes.
