Codeplay has written up a detailed run through of how they how they ensure C++ fundamental types are translated correctly from SYCL code through to OpenCL, retaining their correct size and signedness. If you're an application developer, this will help you learn a little about how SYCL works under the hood. If you're looking to implement SYCL, this will help you find a way to get the compiler to do your lifting for you.

Vulkan Continues To Show Its Gaming Strength On Low-End Hardware

• Tags:

While current generation Linux games with current Linux GPU drivers using the Vulkan API rather than OpenGL may not be significantly faster with higher-end hardware right, the impact of this newer Khronos graphics API tends to be more profound on lower-end hardware, especially when it comes to lightening the load on the CPU. Following recent Pentium vs. Ryzen 3 Linux gaming tests, Phoronix carried out some fresh benchmarks looking at OpenGL vs. Vulkan on the Ryzen 3 1200 quad-core CPU with NVIDIA and Radeon graphics.

Imagination Technologies announces the PowerVR CLDNN SDK for developing neural network applications on PowerVR GPUs. The neural network SDK makes it easy for developers to create Convolutional Neural Networks (CNNs) using PowerVR hardware. CLDNN sits on top of OpenCL making use of OpenCL constructs so it can be used alongside other custom OpenCL code. It uses standard OpenCL memory, so it can be used alongside standard OpenGL ES contexts. Learn more about CLDNN and download the SDK today.

ComputeCpp v0.5.0 is released and SYCL 1.2.1 ratified

• Tags:

The Khronos recently announced SYCL 1.2.1. The SYCL 1.2.1 specification has improved on the existing 1.2 standard by introducing new features which allow for better integration with existing machine learning and OpenCL-based frameworks such as TensorFlow as well as various improvements based on user feedback. This is an exciting piece of news for Codeplay is it enables them to work towards full compliance of SYCL 1.2.1 for ComputeCpp, and their v0.5 release which is now available to download.

New Optimized OpenGL/Graphics Math (glm) for C - feedback requested

• Tags:

There is a new optimized OpenGL/Graphics Math for C. The original glm library is for C++ only (templates, namespaces, classes...). This new library is targeted to C99 but currently you can use it for C89 safely by language extensions. Almost all functions (inline versions) and parameters are documented inside related headers. Complete documentation is in progress. Feedback is welcome on the OpenGL forums.
