PerfDoc is a Vulkan layer which aims to validate applications against the Mali Application Developer Best Practices Guide. Just like the LunarG validation layers, this layer tracks your application and attempts to find API usage which is discouraged. PerfDoc focuses on checks which can be done up-front, and checks which can portably run on all platforms which support Vulkan. The intended use of PerfDoc is to be used during development to catch potential performance issues early. The layer will run on any Vulkan implementation, so Mali-related optimizations can be found even when doing bringup on desktop platforms. Just like Vulkan validation layers, errors are reported either through VK_EXT_debug_report to the application as callbacks, or via console/logcat if enabled. Dynamic checking (i.e. profiling) of how an application is behaving in run-time is not currently in the scope of PerfDoc. Some heuristics in PerfDoc are based on "arbitrary limits" in case where there is no obvious limit to use. These values can be tweaked later via config files if needed. Some checks which are CPU intensive (index scanning for example), can also be disabled by the config file. Please visit the GitHub repository for PerfDoc.
Mozilla announced a new development program for Mixed Reality that will expand its work in Virtual Reality (VR) and Augmented Reality (AR) for the web. There is a draft WebXR API proposal, which uses WebGL, for providing access to both augmented and virtual reality devices.
Last year, Intel acquired FPGA-focused Khronos member Altera. Intel has now announced a new line of hybrid chips that combine FPGAs with their well-known CPUs. One of the more interesting aspects of the new Intel FPGA ecosystem is the Acceleration Stack, an OpenCL based programming environment that can be used by developers for hybrid cards or discrete cards, including FPGAs, CPUs, and GPUs. The stack abstracts the programming required for the FPGAs to streamline and speed up development for accelerators and applications being used. Additionally, it allows for code to be reusable — porting between FPGAs/GPU/CPU should be possible without major changes. OpenCL, a C based programming language, will. This is quite the opposite of what had been available when Intel released the E600C seven years ago.
RedGamingTech recently posted Part I of an interview with Neil Trevett - 'CUDA, AI, Self Driving Cars, GameWorks & Deep Learning', President of The Khronos Group. Part II 'Vulkan, Game Development & VR & Graphics Technology' of the interview is now online.
Linux Graphics Debugger is a 3D graphics development tool that allows developers to debug and profile OpenGL 4.x on Linux. NVIDIA® Linux Graphics Debugger version 2 is now available with many new features and improvements.
A new Codeplay post we presents a utility to facilitate the integration of SYCL into existing codebases that are not C++11 friendly. If your application uses malloc and frees for allocation, or has some existing CUDA®-based memory management, the "Legacy Pointer" and/or the "Managed Virtual Pointer" utilities can help you to integrate your code with SYCL.
Immersed is the East Coast event for industry and professionals working with technologies like virtual reality, mixed reality, augmented reality, stereoscopic 3D, and more.
