Correct synchronization is needed to ensure correct results from Vulkan operations (whether graphical or computational). Modern graphics hardware is both parallel and pipelined, with various operations happening simultaneously for performance reasons. Vulkan has a limited number of ordering guarantees but, for most operations, it is the application's responsibility to inform the implementation when ordering is required between operations. The ne

The Khronos ANARI™ (Analytic Rendering Interface) working group is defining an open, royalty-free API standard for cross-vendor access to state-of-the-art rendering engines. ANARI will enable experts in domains such as scientific visualization to leverage the latest rendering techniques without needing to use low-level rendering APIs. Graphics vendors will use the ANARI API to enable visualization engines, libraries, and applications with p

Over the past decade, the use of accelerator architectures and, in particular, GPUs, in high performance computing (HPC) has skyrocketed. Of the Top 500 list of supercomputers from June 2010, only three systems out of the top 50 used accelerator architectures. In the June 2020 list, the number has increased to 27. In addition to the largest supercomputers in the world embracing the performance and efficiency advantages of accelerators for many da
