Public proposals for standards groups

Codeplay Software Ltd.

Objective of the repository

This repository contains different proposals on various working groups that Codeplay Software Ltd. is currently involved in.

The aim of this public repository is to facilitate sharing information with our partners and public in general.

Structure of the repository

Each proposal is stored on a separate directory, named after the proposal itself. Inside the directory, some proposals may have different directories for different working groups or standards - for example, some proposals may be combined for Khronos SYCL for OpenCL and ISO C++.

How to contribute

We encourage interested users and developers in the community to contribute to our proposals. Feedback can be sent via Github issues, or by forking the repository and contributing pull requests.

Developers and members of the community can contact us directly via our website.

Status of the proposals

This repository contains proposals in different states of work, some of them will be work in progress while others are published and finished. Each proposal in the table below will be tagged with one of the following states:

• Work In Progress : The proposal is still a work in progress, so large changes should be expected.
• Draft : A draft of the proposal is ready, and no major changes are expected. This status normally indicates that the proposal is ready for feedback from the general public.
• Final Draft : The proposal is a draft submitted to the relevant standards body, and only minor changes are expected.
• Published : The proposal is finished and no more work is expected.
• Accepted, Accepted with changes or Partially accepted : Accepted on the standard version indicated as target. Refer to that standard document from now on for the latest status of the feature.
• Dropped : The proposal has been dropped in some stage, either replaced by other proposal or because it was no longer of interest. No further updates are expected on the proposal text, and may be eliminated from this registry in the future.
