NVIDIA cuDNN

What NVIDIA cuDNN is

NVIDIA cuDNN is a GPU-accelerated library of primitives for deep neural networks. It provides tuned implementations for convolution, attention, matrix multiplication, pooling and normalization. Its Graph API models operations as nodes connected by tensors and supports flexible fusions around matrix multiplication and convolution, along with specialized patterns for attention and convolution with normalization. NVIDIA recommends an open-source Python/C++ Frontend API for using the Graph API; a lower-level C Backend API is also available. cuDNN accelerates frameworks including PyTorch, JAX, Caffe2, Chainer, Keras, MATLAB, MxNet, PaddlePaddle and TensorFlow. Downloads and installation routes include pip, Docker and package managers. The backend supports Linux and Windows, while the listed platforms also include self-hosted use. It is free under the NVIDIA Software License Agreement. Compatible operating system, CUDA, driver and NVIDIA hardware versions are required, with current details in NVIDIA’s support matrix. Only one CUDA Toolkit version of cuDNN 9 can be installed at a time.

Who it suits

It suits developers and teams using compatible NVIDIA hardware to accelerate deep-learning frameworks or operations. Its Graph API and language interfaces are relevant to users building GPU-based workflows.

Limits

cuDNN requires compatible operating system, CUDA, driver, and NVIDIA hardware versions. Only one CUDA Toolkit version of cuDNN 9 can be installed at a time.

Getting started
