OpenCL Adoption and Conformance Testing

OpenCL Adopter Login

Any company may freely use the publicly released OpenCL specification to create a product, but implementations of the OpenCL API must be tested for conformance in the Khronos OpenCL Adopters program before the OpenCL name or logo may be used in association with an implementation of the API.

Implementers may join the Khronos OpenCL Adopters Program which enables them to download and execute the OpenCL conformance tests and upload the results for peer review within Khronos.  If the implementation successfully passes the tests, the Adopter is granted a royalty-free trademark license to use the OpenCL name and logo in association with that implementation - and they can refer to the implementation as being OpenCL conformant or OpenCL compliant.

Benefits of the OpenCL Adopters program:

  • Access to the OpenCL conformance test source code
  • Participation in the OpenCL Adopters technical Mailing list - a private priority channel for two-way interaction with the OpenCL working group over the specification and conformance tests
  • Conformant products may use the OpenCL name and logo
  • Company listing on the Adopting Members and Conformant Products pages
