Khronos Group

The OpenCL Working Group has published the first in a series of cooperative matrix extensions — and your feedback can help shape them before finalization.

cl_khr_cooperative_matrix brings cooperative matrix load, store, and multiply-add to OpenCL, developed with Arm, Intel, and Qualcomm. A companion OpenCL C language extension is also in RFC.

The glTF Working Group at Khronos is excited to announce two significant website upgrades at the center of the glTF developer ecosystem:

- A new landing page for the glTF Sample Assets GitHub repository provides a polished and powerful new web front-end.

- The glTF Render Fidelity Comparison website has undergone a modern redesign to deliver clear, side-by-side render fidelity comparisons.

The SPIR-V Working Group has issued a Request for Comment on a new extension proposal called SPV_KHR_poison_freeze. This extension proposes a method to provide tighter undefined values and require that instructions performing simple data transformations do not result in undefined behavior in common cases.
