There are several great Khronos related meetings for April 2019: “OpenXR 0.90 Provisional Specification Review” on April 10th in Cambridge MA USA, “Munich Meetup April 2019” on April 12th in Munich Germany with Dr Chajdas and friends covering Vulkan, SPIR-V and GLSL, and starting on April 16th is a three part meet up on “A Gentle Introduction to Shaders 1” in London UK. Learn more about these meet ups and how Khronos can help support your Khronos related meet up.

Radeon GPU Analyzer (RGA) is thte AMD offline compiler and integrated code analysis tool, supporting the high-level shading and kernel languages that are consumed by DirectX 11, Vulkan, OpenGL and OpenCL, including HLSL, GLSL, the OpenCL kernel language, and SPIR-V. Along with support for Vulkan in the RGA GUI, the biggest new feature in RGA 2.1 is a new analysis system that lets you obtain the GCN machine ISA and hardware resource information, using the compiler in the running driver that you have in your system. Learn more on the Radeon GPU Blog from AMD.

Illya Rudkin, Principal Engineer Safety-Critical Software, Alastair Murray, Principal Software Engineer and Victor Lomuller, Senior Software Engineer Compilers and SPIR-V, will be attending this year’s Khronos F2F event in San Diego from 21st to the 25th January, 2019. Illya, Alastair and Victor would be delighted to speak to anyone attending the event interested in connecting Artificial Intelligence to Silicon. Please track them down via LinkedIn or using their contact form on Codeplay’s website or follow them on Twitter @codeplaysoft.

Shader Conductor is one of several open-source projects for going from one shading language to another. With Microsoft’s Shader Conductor the focus is on converting HLSL to GLSL or SPIR-V (OpenGL/Vulkan), ESSL (OpenGL ES), MSL (Apple Metal), and older HLSL shader models. Shader Conductor can handle all shader stages, including geometry and compute shaders. Learn more about this new Open Source project from Microsoft.

The Khronos Group has made public the SPIRV LLVM Translator Github repository which contains source code for the LLVM/SPIR-V Bi-Directional Translator, a library for translating between LLVM and SPIR-V. The LLVM/SPIR-V Bi-Directional Translator is open source software.

The Khronos Group announces the release of the Vulkan 1.1 and SPIR-V 1.3 specifications. Version 1.1 expands Vulkan’s core functionality with developer-requested features, such as subgroup operations, while integrating a wide range of proven extensions from Vulkan 1.0. Khronos will also release full Vulkan 1.1 conformance tests into open source and AMD, Arm, Imagination, Intel Corporation, NVIDIA and Qualcomm have implemented conformant Vulkan 1.1 drivers.



Vulkan now ships natively on almost all GPU-enabled platforms, including Windows 7, 8.X, 10, Android 7.0+ and Linux, plus Khronos recently announced open source tools to enable Vulkan 1.0 applications to be ported to macOS and iOS. Vulkan has widespread support in leading games engines including Unreal, Unity, Source 2 from Valve, id Tech, CroTeam’s Serious Engine, CryEngine, and Xenko. Vulkan is being used in over 30 cutting-edge games on diverse desktop and mobile platforms, including Doom, Quake, Roblox, The Talos Principle, Dota 2, and is the exclusive API used in AAA titles such as Wolfenstein II and Doom VFR.

LunarG announces SPIR-V size reduction with -Os option

LunarG 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.

How The Khronos Group Intends to get us to a unified graphics future

Neil Trevett, President of The Khronos Group, talks to Architosh in this two-part series about OpenGL and the future of graphics standards. On the eve of SIGGRAPH 2017 Neil Trevett spoke to Architosh about the evolving OpenGL standard as well as directions the group is taking to plot a path for a universal graphics API that engages the use of low-level APIs. Read more about why OpenGL isn’t packing for retirement just yet a the key thing in OpenGL 4.6 is SPIR-V is part of core.

Only a few days after the 1.35.x release, GPU Caps Viewer 1.36.x has been released with support for OpenGL 4.6. OpenGL 4.6 introduces the support of SPIR-V modules in OpenGL and the set of SPIR-V extensions is listed exposed in the OpenGL panel. There are a few Vulkan improvements as well in this version. GPU Caps Viewer is a graphics card information utility focused on the OpenGL, Vulkan, OpenCL and CUDA API level support of the main (primary) graphics card.

Khronos Releases OpenCL 2.2 With SPIR-V 1.2

The Khronos Group announces the immediate availability of the finalized OpenCL™ 2.2 specification, incorporating industry feedback received from developers during the provisional specification review period. In addition to releasing the specification in final form, Khronos has, for the first time, released the full source of the specifications and conformance tests for OpenCL 2.2 onto GitHub to enable deeper community engagement. The conformance tests for OpenCL versions 1.2, 2.0 and 2.1 have also been released on GitHub with more open-source releases to follow. The Windsor Testing Framework, also released today, enables developers to quickly install and configure the OpenCL Conformance Test Suite on their own systems. Developers who know OpenCL C and plan to port their kernels to OpenCL C++, the OpenCL C to OpenCL C++ Porting Guidelines have been released.
