baracuda-cudnn-sys
Raw FFI bindings + dynamic loader for NVIDIA cuDNN — deep-learning primitive ops (convolution, pooling, activation, normalization, RNN, attention, ...).
Symbols resolve lazily via libloading;
no link-time dependency on libcudnn.so / cudnn64_*.dll.
cuDNN 9's main DLL on Windows is a facade that depends on companion
DLLs (cudnn_ops64_9.dll, cudnn_graph64_9.dll, ...) in the same
directory. This crate's loader detects that and adds the cuDNN bin
directory to PATH on Windows so LoadLibraryExW resolves the
companions.
Most users want baracuda-cudnn — that crate exposes typed
descriptors for tensors / filters / convolutions / RNNs, the classic op
API (forward + backward), and the modern Backend (Graph) API
scaffolding.
What's exposed
- All
cudnnHandle_t/cudnnTensorDescriptor_t/cudnnFilterDescriptor_t/cudnnConvolutionDescriptor_tetc. types. - Classic op API: activation, convolution forward + backward (data / filter / bias), pooling, softmax, batch-norm (inference / training / backward), LRN, dropout, op-tensor, reduce, transform, add, scale, spatial transformer, CTC loss, RNN forward + backward.
- Backend (Graph) API for cuDNN v8+ — descriptors, attribute setters, finalize/execute.
