How many branches can your CPU predict?

Modern processors have the ability to execute many instructions per cycle, on a single core. To be able to execute many instructions per cycle in practice, processors predict branches. I have made the point over the years that modern CPUs have an incredible ability to predict branches. It makes benchmarking difficult because if you test … Continue reading How many branches can your CPU predict?

작은 개선을 꾸준히 쌓는 방식의 장점을 칭찬하는 글로, 대박을 노리는 접근이 아니라 직교하는 10% 내외의 개선을 착실히 반복하고 성능 자체보다 Token Efficiency(토큰 효율성)에 초점을 맞춰 '같은 loss에 도달하는 시간'을 얼마나 단축했는지에 주목해야 한다는 연구·개발 방식에 대한 의견이다.

こういう細かな改善を積み重ねるの日本人得意だったよね > 大穴狙いではなく、直交する10数%改善を着実に積むことと、性能そのものではなくToken Efficiencyで統一していた。同じlossまでの時間を何%縮めたかに注目している

I put "my penis is shrinking" in the bot and this is what I got

I am currently navigating a period of significant downsizing and streamlining within my personal core infrastructure. This strategic reduction in scale is part of a broader commitment to lean optimization and maximizing efficiency in high-impact environments. #GrowthMindset #Optimization #PersonalBranding #AgileTransformation

New Use Case Drop: IterX를 사용해 pbrt-v4의 CPU 핫스팟을 최적화했습니다. 광선당 불필요한 작업을 줄여 트래버설, 교차(intersection), 스펙트럼 연산, 볼류메트릭 샘플링 등 물리 기반 렌더링의 핵심 병목을 해결했으며, AMD EPYC 환경에서 성능 향상을 확인한 실사용 최적화 사례를 제시합니다.

🧑‍🍳New Use Case Drop! 🧐We used IterX to optimize pbrt-v4’s hottest CPU paths, tackling a core bottleneck in physically based rendering: the cost of doing more work per ray than necessary during traversal, intersection, spectrum math, and volumetric sampling. 🥳On an AMD EPYC

🚀 Oh, look! Another riveting exploration of mathematical function #optimization that will surely redefine human existence. Apparently, the key to faster asin() was hiding in plain sight, and we bet it was right next to the cure for world hunger. 🙄 Let's all just take a moment to thank the gods of #trigonometry for this groundbreaking revelation. 🥳
