...this is nice bait, I clicked.

Honestly I like boomer loops. Boomer loops are simple, easy to understand, you just have to avoid sticking twenty-seven of those inside one gigantic function like our current codebase.

FLOSS Weekly: Episode 857: SOCification This week Jonathan chats with Konstantinos Margaritis about SIMD programming. Why do these wide data instructions matter? What's the state of Hyperscan, the project from Intel to power regex with SIMD? And what is Konstantinos' connection to ARM's SIMD approach? Listen to find out! You can join the conversation in , watch live or get the video version of the show on , as well as getting the full story and show links from . Oh, and follow !

This is right up my alley. A discussion about the merits of the various #simd implementations. There is even a mention of #linaro and #arm in the episode. #FLOSS Weekly: Episode 857: SOCification b27a1a7a-dbb9-4922-ac3e-601e2d6ca1e1.libsyn.com/episode-857-socification #podcast

@riffraff Functional approach as more strict opens the compiler new doors for optimisation of the code going up to use of #SIMD.

SIMD coding is hard: platforms, inconsistencies, lane constraints... but xsimd abstracts a lot away. With my first contributions, I improved byte shuffling, now available in the latest 14.0 release.

It's time for #AdventOfCode! This year I'm using #C #neovim #makefile. I'm going to focus on performance, using #SIMD instructions where possible on a #RaspberryPi

Porting DirectX Math to pure C. Taking some inspiration from cglm as well.

Fixing rust-lang stdarch issues in LLVM - Blog - Tweede golf A couple of months ago I became a co-maintainer of rust-lang/stdarch, which defines vendor-specific APIs that are used by the Rust standard library and Rust users writing explicit SIMD code.

Folkert has become a co-maintainer of rust-lang/stdarch, which defines vendor-specific APIs that are used by the Rust standard library and Rust users writing explicit SIMD code.

In this blog, Folkert explains how they try to reduce the maintenance burden: buff.ly/X0F6yei

Vectorizing Molecular Docking: Boosting CPU Performance and Portability

A study finds auto‑vectorization with -O3 nearly matches hand‑written SIMD for molecular docking; x86 CPUs have raw performance over ARM, while ARM offers similar energy efficiency Read more: getnews.me/vectorizing-molecular-do... #cpu #simd

SIMD: A Practical Guide A Guide for Writing High-Performance Vectorized Code

Modern CPU performance isn’t just about clockspeed—it’s about how you write your code.

SIMD lets a single instruction operate on multiple data points.
Caden Parker breaks it down in this clear, practical guide.

#SIMD #Vectorization #SystemsProgramming

Hacker News debated a faster Zig substring search using SIMD. Discussion covered performance, potential optimizations, and the broader impact of SIMD across architectures & languages. Key topics included worst-case scenarios and instruction set trade-offs. #SIMD 1/6

C++ std::simd (ok, std::datapar) is cool. Portable, order-of-magnitude speedups (w/ modern CPUs and the right, flop intense algorithms) 🚀 #HPC #SIMD

Achieving peak performance often requires SIMD optimizations. Handwritten assembly or intrinsics frequently outperform compilers because they allow for specific algorithmic and data structure redesigns that auto-vectorization can't achieve. This is where the big wins are. #SIMD 3/6
