The Khronos Group Releases the OpenCL 3.0 Provisional Specifications


OpenCL LogoOpenCL™ 3.0 realigns the OpenCL roadmap to enable developer-requested functionality to be broadly deployed by hardware vendors, and it significantly increases deployment flexibility by empowering conformant OpenCL implementations to focus on functionality relevant to their target markets. OpenCL 3.0 also integrates subgroup functionality into the core specification, ships with a new OpenCL C 3.0 language specification, uses a new unified specification format, and introduces extensions for asynchronous data copies to enable a new class of embedded processors. The provisional OpenCL 3.0 specifications enable the developer community to provide feedback on GitHub before the specifications and conformance tests are finalized. Read more...

Game Developer Adoption and Attitudes Towards ASTC Texture Compression


Vulkan OpenGL LogoASTC (Adaptable Scalable Texture Compression) is an exceptionally efficient compression technology, which allows encoding of a wide variety of texture formats at bit-rates of 8 bits per pixel to below 1 bit per pixel. ASTC was contributed by Arm, developed under the cooperative process at Khronos and is royalty-free when used with Khronos’ OpenGL® ES and Vulkan® APIs. ASTC enables the size of textures used in 3D games and applications to be significantly reduced while being downloaded and stored – saving memory size, access bandwidth and reducing overall application size while retaining high image quality.

SYCL - The Dawn of a Unified Programming Model for Heterogeneous Modern C++ at SC19

 

SYCL LogoIn a new blog series, guest blogger and SYCL™ Working Group Chair, Michael Wong, will talk about SYCL and the SYCL Working Group’s activities. In this first blog, Michael tells of his experience at SC19 with SYCL and Intel’s oneAPI that implements the SYCL standard. In future blogs, Michael plans to tell us more about SYCL features and future directions.
