Intel® oneAPI Deep Neural Network Library

Increase Deep Learning Framework Performance on CPUs and GPUs

Develop Faster Deep Learning Frameworks and Applications

The Intel® oneAPI Deep Neural Network Library (oneDNN) provides highly optimized implementations of deep learning building blocks. With this open source, cross-platform library, deep learning application and framework developers can use the same API for CPUs, GPUs, or both—it abstracts out instruction sets and other complexities of performance optimization.

Using this library, you can:

  • Improve performance of frameworks you already use, such as OpenVINO™ toolkit, Intel® AI Analytics Toolkit, Intel® Distribution for PyTorch*, and Intel® Distribution for TensorFlow*.
  • Develop faster deep learning applications and frameworks using optimized building blocks.
  • Deploy applications optimized for Intel® CPUs and GPUs without writing any target-specific code.
Download as Part of the Toolkit

oneDNN is included as part of the Intel oneAPI Base Toolkit, which is a core set of tools and libraries for developing high-performance, data-centric applications across diverse architectures.

Download the Stand-Alone Version

A stand-alone download of oneDNN is available. You can download binaries from Intel or choose your preferred repository.

Abstract Programming Model

  • Primitive: Any low-level operation from which more complex operations are constructed, such as convolution, data format reorder, and memory
  • Memory: Handles to memory allocated on a specific engine, tensor dimensions, data type, and memory format
  • Engine: A hardware processing unit, such as a CPU or GPU
  • Stream: A queue of primitive operations on an engine
