Khronos member Axell to start selling OpenVG 1.1 compliant AG903

Axell will start production of the AG903, the latest product in the "AG9" series graphics LSI for embedded systems. As with existing products, it has strengths not only in functionality and performance, but also in the supply and support. It is the LSI for industrial devices used in the factory automation, measurement, and medical equipments, among others. The AG903 is in conformance with OpenVG 1.1 and uses the ARM Cortex-A5 for it's built in CPU.

Leveraging asynchronous queues for concurrent execution

GPUOpen has posted a new entry "Leveraging asynchronous queues for concurrent execution." Understanding concurrency (and what breaks it) is extremely important when optimizing for modern GPUs. Modern APIs like Vulkan provide the ability to schedule tasks asynchronously, which can enable higher GPU utilization with relatively little effort.

Amazon EC2 Elastic GPUs support OpenGL

Amazon EC2 users will soon have the ability to add OpenGL acceleration to existing EC2 instance types. Amazon-optimized OpenGL library will automatically detect and make use of Elastic GPUs. Amazon will start out with Windows support for OpenGL, and plan to add support for the Amazon Linux AMI and other versions of OpenGL after that. The GPU added to the instance can have 1, 2, 4, or 8 gigabytes of video memory. It’s becoming much easier to use OpenGL from GPUs in the cloud.

NVIDIA GTX 680 To GTX 1080 Blender OpenCL Benchmarks

Phoronix has published benchmarks of 13 Kepler/Maxwell/Pascal NVIDIA GeForce graphics cards when testing Blender 2.78's OpenCL renderer. Unfortunately, no AMD OpenCL benchmarks for Blender yet -- the current open-source stack doesn't work until ROCm OpenCL support comes into play and the AMDGPU-PRO stack wasn't working for Blender OpenCL but was falling back to CPU rendering. Read the complete article.

Vulkan barriers explained

AMD post from October explaining Vulkan's Barrier system. Vulkan’s barrier system is unique as it not only requires you to provide what resources are transitioning, but also specify a source and destination pipeline stage. This allows for more fine-grained control of when a transition is executed. However, you can also leave quite some performance on the table if you just use the simple way, so today we’re going to look at vkCmdPipelineBarrier in detail.
