Summary

Can someone make a pull request against this for OpenCL suite proposal. It's fine to add WIP so we understand it's for reference review.

Motivation

We are waiting for a while for this to be able to abstract GPU API and be able to decide what we do with VK, Metal,.... It should be OCL 3.0 compliant too now :)

Problem

Certain hosts (like those who support multi-GPU on Windows GTX/RTX cards) cannot support the OpenGL suite, another API is necessary to allow that.

Impact

The preliminary suite has been reviewed by 3 members.

Documentation Impact

A new header file would be added.

Surely OpenCL is pretty much dead and buried now?
