NVIDIA Developers Express Interest In Helping Out libc++/libstdc++ Parallel Algorithms
NVIDIA developers have expressed interest in helping the open-source GCC libstdc++ and LLVM Clang libc++ standard libraries in bringing up support for the standardized parallel algorithms.
C++17 brings parallelized versions for some of the algorithms exposed by the C++ standard library, but sadly GCC's libstdc++ and LLVM's libc++ do not yet support these parallel algorithms while the rest of their C++17 support is in great shape. Going back over a year Intel has been interested in contributing parallel support code to these C++ standard libraries that could be shared by both projects. The Intel path builds in abstractions for supporting different underlying thread/parallelism APIs.

The Rust-Written Kazan Vulkan Driver Lights Up Its Shader Compiler
This week the Kazan project (formerly known as "Vulkan-CPU") celebrated a small but important milestone in its trek to having a CPU-based Vulkan software implementation.
As a refresher, Kazan is the project born as Vulkan-CPU during the 2017 Google Summer of Code. The work was started by student developer Jacob Lifshay and he made good progress last summer on the foundation of the project and continued contributing past the conclusion of that Google-funded program. By the end of the summer he was able to run some simple Vulkan compute tests. He also renamed Vulkan-CPU to Kazan (Japanese for "volcano").

Panfrost Open-Source GPU Driver Continues Advancing For Mali GPUs
The Panfrost open-source, community-driven, reverse-engineered graphics driver for ARM Mali graphics processors continues panning out pretty well.
Alyssa Rosenzweig has provided an update this weekend on the state of Panfrost for open-source Mali 3D support. The developers involved have been working out some texture issues, various OpenGL / GLES issues around GLMark2, and support now for running Wayland's Weston reference compositor.

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. |
