LunarG announces SPIR-V size reduction with -Os optionLunarG is pleased to announce the release of a new option in spirv-opt, which was designed to reduce SPIR-V size. This new option, -Os, allows developers to reduce SPIR-V size without specifying individual passes of spirv-opt. Learn more about this option at LunarG. For those developers who wish to have finer control over which passes are invoked, read more details about the available SPIR-V optimization options in the white paper by Greg Fischer of LunarG, titled SPIR-V Shader Size Reduction Using spirv-opt_v1.1.

Geeks 3D has a great overview of the new OpenGL and Vulkan features in the AMD Adrenalin 17.12.1 release. AMD has added some OpenGL 4.6 extensions (GL_ARB_gl_spirv) but not all, so Adrenalin 17.12.1 is still an OpenGL 4.5 driver with OpenGL 4.6 features. This driver exposes 319 OpenGL extensions (GL=294 and WGL=25) for a Radeon RX 470 on Windows 10 64-bit. Adrenalin 17.12.1 also exposes Vulkan 1.0.65 which is one of the latest specifications. Vulkan support has been added to Radeon Overlay, Radeon Relive, Enhanced Sync and Frame rate target control.

Neil Trevett, Khronos Group President and Radhakrishna Giduthuri, Software Architecture and Compute Performance Acceleration at AMD, spoke at two Khronos related events this past week. Neils presented was an update on the Khronos Standards for Vision and Machine Learning which covered Khronos Standards OpenVX, NNEF, OpenCL, SYCL and Vulkan. Radhakrishna presented Standards for Neural Networks Acceleration and Deployment covered Khronos Standards OpenVX and NNEF. The slides from both presentations are now online.

Blog: Machine learning’s fragmentation problem — and the solution from Khronos, NNEFThere is a wide range of open-source deep learning training networks available today offering researchers and designers plenty of choice when they are setting up their project. Caffe, Tensorflow, Chainer, Theano, Caffe2, the list goes on and is getting longer all the time. This diversity is great for encouraging innovation, as the different approaches taken by the various frameworks make it possible to access a very wide range of capabilities, and, of course, to add functionality that’s then given back to the community. This helps to drive the virtuous cycle of innovation.

Earlier this year, Microsoft acquired Simplygon, a leader in 3D model optimization based in southern Sweden. Today,Microsoft announces the launch of Simplygon Cloud on Azure Marketplace. Simplygon reduces complexity in the creation and extensibility of 3D models through optimization. Simplygon supports glTF, FBX and OBJ file types for ingestion; rendering engines including Unity 3D and Unreal Engine; and all major mixed reality platforms, including Windows Mixed Reality, iOS and Android.

The Khronos Group announces the ratification and public release of the finalized SYCL 1.2.1 specification. SYCL for OpenCL enables code for heterogeneous processors to be written in a “single-source” style using completely standard modern C++. The multi-vendor SYCL 1.2.1 standard is available royalty-free for industry use, and the full specification together with details about the SYCL open-sourced conformance test suite and Adopters Program are online.

The Khronos Group was at SIGGRAPH Asia this year with talks from several Khronos members including NVIDIA and Unity, as well as a talk from the Khronos Melbourne Chapter Leader. Neil Trevett, President of the Khronos Group, gave an overview of the Khronos ecosystem. If you are interested in learning more about Khronos standards for 3D, VR, AR and Neural Networks, be sure to take a few minutes to read Neil's presentation.

Khronos held an OpenXR panel at the 2017 VRDC session (GDC) with developers Yuval Boger, Joe Ludwig, Kaye Mason, Paul Pedriana and Nick Whiting. The panel provided new updates on the goals, content and status of the effort to create a widely accepted VR API for developers called OpenXR. Learn more about OpenXR or watch the video on Youtube.

Codeplay has set out its intention to lead the development of guidelines to ensure that standards like OpenCL and SYCL meet the strict safety requirements for a range of industries by leading the Khronos SCAP. Illya Rudkin, Principal Software Engineer at Codeplay, is now leading the Khronos Safety Critical Advisory Panel and continues the work done by Erik Noreke to establish the panel. Erik was a long time member of Khronos and well respected for his leadership in numerous working groups. On his appointment Illya said "My role is to continue the work by Erik and grow the participation of both Khronos members and external safety experts within the group. I also hope to enable the group to bring current and new open standards into the safety domain. The demand for safety critical software is growing and we have to ensure adopters of our standards can implement complex systems, often involving multiple layers, as efficiently possible with minimal concerns to safety cases." Learn more about the goals that Illya has for The Safety Critical Advisory Panel. Please contact Khronos if you would like more information about becoming a member, or joining and advisory panel.

Khronos Releases Updated OpenVX Adopters ProgramThe Khronos Group announces an updated Adopters Program for OpenVX, the open, cross-platform, royalty-free standard for computer vision and inferencing acceleration. The updated OpenVX Adopters Program includes a new version of the full conformance tests for the latest iteration of the standard, OpenVX 1.2, and the process by which Adopters can run those tests and submit the results for working group review. Once these tests are successfully passed, Adopters are enabled to label their product as OpenVX conformant, use a royalty-free trademark license for the OpenVX name and logo in association with their implementation, gain protection from the Khronos IP framework and enjoy marketing promotion from the Khronos Group.
