The Khronos Group’s ANARI Working Group has issued a Request for Proposal. The working group has developed the ANARI software development kit (SDK) which needs an associated conformance test suite (CTS) to validate vendor implementations against the specification through the SDK. This project will develop a project plan with the ANARI working group for implementing the ANARI CTS. All submissions must be sent to [email protected] by 5PM PT on Friday May 27th, 2022. Please see a complete list of our RFPs here.

With the release of Portable Computing Language (POCL) 3.0-RC1, there is now initial support for OpenCL 3.0 running on CPUs with LLVM 14+. In addition, LLVM/Clang 14 support and improved tracing, scripts for converting traces into Chromium trace visualizer format are new major features.

The Virtual Dimension Center is Germany’s leading network for Virtual Engineering. Since 2002, the VDC creates synergies between the network members and supports technology transfer. Today, approximately 100 members and partners - among them research institutions, technology suppliers, service providers, users and multipliers - are working in the topics of Simulation, Visualisation, Product Lifecycle Management (PLM), Computer Aided Engineering (CAE) and Virtual Reality (VR) along the whole value chain Virtual Engineering together. Hence they benefit of a higher Innovation activity and productivity due to information and cost advantages compared to companies outside the network. The competitive advantages are a result of transparent competences, raised information flow and easier business contacts.

The New York Times Research and Development team applies emerging technologies in service of our company’s mission to seek the truth and help people understand the world. Using new technologies and formats, we develop technical capabilities for our newsroom and new forms of storytelling for our readers. As part of our method, we evaluate emerging trends in media and technology and forecast how they might play out over the next two to three years. Once we identify an opportunity, we dedicate a team to exploring the space and developing products in collaboration with other parts of our organization.

NaturalPoint, Inc. was founded in 1997 to develop and bring to market high quality image tracking technology and unique computer control devices. Now the largest motion capture provider in the world, NaturalPoint offers high-performance optical tracking solutions at the most affordable prices in the industry.

In this in-depth interview, RedGamingTech sits down with Khronos President, Neil Trevett, to discuss Vulkan and Vulkan 1.3, including upscaling, and revolutionary new tech such as glTF, OpenXR, and the importance of interoperability, and why having a single open source solution is SO important for gaming. Topics include Khronos’ Vulkan, DirectX 12 (including DirectStorage), upsampling / upscaling, how OpenXR could benefit virtual reality / VR devices and more.

NVIDA Rolls Out Multiple Vulkan-related initiatives at GTC 2022

At the recent GTC 2022 Conference NVIDIA released multiple initiatives to boost the productivity of Vulkan developers. The new NVIDIA Nsight Systems 2022.2 system-wide performance analysis tool supports the new Vulkan graphics pipeline library extension and Vulkan memory operations. NVIDIA’s new Streamline open-source, cross-IHV framework can be used to integrate multiple super-resolution technologies into Vulkan games and applications. And lastly, NVIDIA’s new Cloud Playtest virtual development environment that builds on GeForce NOW infrastructure enables the coordination and observation of playtests for Vulkan games without physical hardware or presence.

OpenCL 3.0.11 adds two new extensions and continues the regular release cadence for specification bug fixes and clarifications. The cl_khr_subgroup_rotate extension enables an OpenCL kernel to rotate values among work-items in a subgroup for increased data exchange efficiency in many algorithms. The cl_khr_work_group_uniform_arithmetic extension enables an OpenCL kernel to use new work-group scan and reduction operators which can boost the performance of many use cases—and is ideal to accelerate C++ scan and reduction functions in SYCL 2020 implementations targeting OpenCL as a backend.

GPU Performance API (GPUPerfAPI) is a powerful library providing access to GPU Performance Counters to help analyze the performance and characteristics of applications using a Radeon GPU.

GPUPerfAPI v3.11 adds support for raytracing counters in Vulkan on RDNA2 (Radeon RX 6000 Series) hardware:

  • RayTriTests, and RayBoxTests: These counters collect the number of ray intersections for triangles and boxes, respectively.
  • TotalRayTests: This counter collects the aggregated number of ray-box and ray-triangle intersection tests.
  • RayTestsPerWave: This counter collects ray intersection test count at a more granular level – per wave.

OpenXR is composed of the core feature-set, multi-vendor extensions, and vendor-specific extensions. One of those vendors-specific extensions is VARJO_quad_views, available on Varjo HMDs as the name of the extension indicates. By default, in OpenXR, an application will generate two images, one for each eye. This is known as stereo views. But one unique capability of Varjo HMDs (except the Aero), is to have two displays per eye, allowing human eye resolution in the center area of the screen. The purpose of VARJO_quad_views is to enable the application to generate one view covering the entire field of view at the resolution of the context screen, and one inner view to match with the resolution and field of view of the focus screen (padded for taking into account the head movement and latency).

The VARJO_foveated_rendering extension is augmenting the VARJO_quad_views extension by adding eye tracking. The idea is that every rendered frame the application will be provided a different position of the inner view based on where the eyes are looking at. But also, since we know where the eyes are looking, the size of the inner view is much reduced from the default quad_views. And then the resolution of the outer view can also be reduced, as there is no need to even calculate as many pixels as the context screen can display, because even though it is not as high resolution as the focus screen, it is still higher resolution than the eye can detect at its periphery.

Join us to help drive the evolution of Machine Learning acceleration standards. ML developers lament the growing fragmentation in the ML ecosystem. Khronos knows that open and royalty-free standards can play an essential role in reducing fragmentation, reducing costs, and providing the industry participants the opportunity to grow. Based on feedback from previous summit and discussions, Khronos is creating a coalition of interested parties to meet the needs of the ML community for hardware acceleration.
