Cache-friendly reads, user-hostile writes.
Hey welcome! This is my blog about cpu and software performance, main courses will be SWAR tricks, bit-twiddling a bunch of simd, stopping the cpu from predicting the future and whatever stupid low level stuff i find fun enough to write about.
I’m Giuseppe and currently the only person here. I put a genuinely stupid amount of effort into those posts and in the featured software!
If you’re into this kind of stuff too and want to write something, hit me up, I’d love collabs. Genuinely. Co-authoring, guest posts, “Hey I think your benchmark is wrong”, everything welcome
Also: don’t take anything here too seriously. I will absolutely get things wrong sometimes, I will absolutely make jokes about it, and if you spot a mistake, telling me is a gift, not an attack. This is a silly billy blog written by someone who cares too much.
If you used something from here and it made your code faster, I’d love to hear about it.
If you published something where this blog helped you get there, let me know too — it would genuinely make my day.
