Clang 21 Delivering Nice Performance Gains On AMD EPYC Zen 4 With HBM3

One of the areas I've been meaning to run more benchmarks on this season has been for the recently released Clang 21 compiler. Back in September when LLVM Clang 21 was debuting I ran some initial benchmarks and found it to deliver some nice performance gains on AMD EPYC Zen 5 but then have been busy with other benchmarks/articles for expanding that testing. Recently with having some spare cycles and gratis access still to the Microsoft Azure HBv5 instance for AMD EPYC Zen 4 with HBM3, I ran some Clang 20 vs. Clang 21 performance benchmarks there for those wondering about any performance benefits of this new compiler release on Zen 4.

Canonical Gets Flutter Up And Running On RISC-V For Ubuntu

Canonical has been bullish on RISC-V with Ubuntu being one of the most common Linux distributions endorsed by RISC-V board vendors. Canonical also has been bullish on the Flutter toolkit for crafting their desktop installer UI and other modern UI/app interfaces. But these two together haven't panned out with Flutter not currently supporting RISC-V. Canonical has submitted pull requests now for enabling RISC-V support with Flutter...

Linux 6.19 Slated To Land "mm/cid" Rewrite That Has Very Positive Performance Potential

A set of Linux kernel patches posted back in October for rewriting the kernel's memory-mapped concurrency ID code for some nice performance wins looks like it will land for Linux 6.19. This is the code that prominent Intel engineer Thomas Gleixner found to yield up to an 18% improvement for the PostgreSQL database. My testing of this "mm/cid" code has also shown some nice performance wins too...

Rusticl Has Turned Out Remarkably Well For Open-Source OpenCL For Mesa Drivers

Rusticl as a modern OpenCL implementation for Mesa Gallium3D drivers has turned out remarkably well. Rusticl performance has evolved quite well for this Rust-based OpenCL driver and it continues tacking on new features / OpenCL extensions as well as working gracefully with more Mesa drivers. Rusticl lead developer Karol Herbst presented on some of the recent accomplishments for this driver back at XDC2025...
