Compute Library

The Compute Library is a collection of low-level machine learning functions optimized for Arm® Cortex®-A and Arm® Mali™ GPUs architectures.

The library provides superior performance to other open source alternatives and immediate support for new Arm® technologies e.g. SVE2.

Key Features:

  • Open source software available under a permissive MIT license
  • Over 100 machine learning functions for CPU and GPU
  • Multiple convolution algorithms (GeMM, Winograd, FFT, Direct and indirect-GeMM)
  • Support for multiple data types: FP32, FP16, INT8, UINT8, BFLOAT16
  • Micro-architecture optimization for key ML primitives
  • Highly configurable build options enabling lightweight binaries
  • Advanced optimization techniques such as kernel fusion, Fast math enablement and texture utilization
  • Device and workload specific tuning using OpenCL tuner and GeMM optimized heuristics

How to contribute

Contributions to the Compute Library are more than welcome. If you are interested on contributing, please have a look at our how to contribute guidelines.

Developer Certificate of Origin (DCO)

Before the Compute Library accepts your contribution, you need to certify its origin and give us your permission. To manage this process we use the Developer Certificate of Origin (DCO) V1.1 (https://developercertificate.org/)

To indicate that you agree to the the terms of the DCO, you "sign off" your contribution by adding a line with your name and e-mail address to every git commit message:

Signed-off-by: John Doe <john.doe@example.org>

You must use your real name, no pseudonyms or anonymous contributions are accepted.

Public mailing list

For technical discussion, the ComputeLibrary project has a public mailing list: acl-dev@lists.linaro.org The list is open to anyone inside or outside of Arm to self subscribe. In order to subscribe, please visit the following website: https://lists.linaro.org/mailman/listinfo/acl-dev
