Optimizing Circular Gaussian Mask, Krita:GSoC
Previous implementation was based on a slow scalar model, calculating each mask value per coordinate. I implement a new vectorized code using Vc library to allow a robust SIMD usage, calculating the mask values in parallel. Not all operations are implemented on Vc data types, especially erf had to be implemented for Vc data types. The new implementation shows to be up to 10 times faster (on my system) on mask generation. Given that the mask generation requires the most computing on brush stroke generation, this speed improvement holds up even in the full brush stroke benchmarks. Given the way it is implemented the code can become faster as future SIMD registers grows on future CPUs.

What’s in a Qt 3D Studio Scene?
Now that Qt 3D Studio 2.0 has been released, let’s look at what some of the new features enable. In particular, we will visit the so-called in-scene debug and profile views, as these handy, built-in (both to the viewer launched from the editor and, if the developer decides so, to applications) views allow answering questions like What happens between loading a scene and issuing OpenGL draw commands?, Is this 3D scene too heavy?, How much graphics resources does this scene use?, or Is there any chance this scene will perform on this or that embedded hardware?

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
