Standard‑Slope Integration (SSI) — Link to Post #7: Why SSI is general-purpose

A new, first-of-its-kind class of derivative-driven integration operators built solely from slope information.

SSI is real, not a trick — it’s a general-purpose integration operator built from first principles.

Standard‑Slope Integration (SSI) — Post #7: Why SSI is general-purpose A new, first-of-its-kind class of derivative-driven integration operators built solely from slope information. Although SSI excels in difficult cases, it isn’t designed only for failures. Its derivative-driven structure and invariant-preserving iteration make it broadly applicable across smooth, irregular, and mixed-structure integrands. The same reconstruction principles that stabilize challenging cases also perform reliably in ordinary cases, giving SSI a uniquely wide operational range without unnecessary adjustments. This general-purpose behavior follows directly from SSI’s underlying structure and nothing else. #numericalanalysis #scientificcomputing #mathematics #integration #StandardSlopeIntegration #SSI

Oh so the new garbage collector (GC) introduced in Python 3.14.0 was indeed memory hungry! That could explain why a pytest run that was working fine on 3.13 went OOM as soon as I switched it to 3.14. I am glad there is an explanation!
From what I understand the old GC was swapped back on for 3.14.5 and later.

OpenAI가 과학자들을 위한 Codex의 활용이 수학, 물리, 화학, 생물학 등 다양한 분야에서 강한 반응을 얻고 있으며, 현재 기능 개선을 진행 중이라고 밝혔다. 연구·과학 작업에 더 유용한 AI 코딩/에이전트 도구로 발전할 가능성을 보여주는 업데이트다.

We are seeing strong traction and working to improve Codex for scientists across mathematics, physics, chemistry, biology and more. What do you wish it were capable of that it cannot do today?

Start here: Standard-Slope Integration (SSI)

A new, first-of-its-kind class of derivative-driven integration operators built solely from slope information.

If you’re new to my work, this post links to the full SSI series—a structured overview of a first-of-its-kind, derivative-driven integration operator built on structural iteration invariants and slope-based reconstruction. The recap summarizes all seven posts in order and provides the conceptual foundation for understanding SSI.

Standard‑Slope Integration (SSI): Series recap A new, first-of-its-kind class of derivative-driven integration operators built solely from slope information. Over the past several posts, I’ve outlined the core ideas behind Standard-Slope Integration (SSI): 1. Why derivative-driven structure matters 2. How structural iteration invariants stabilize reconstruction 3. Why SSI remains robust in cases of instability or failure 4. How slope-based reconstruction differs from area accumulation 5. How SSI diverges from classical quadrature 6. A simple example of SSI behavior 7. Why the method is genuinely general-purpose Together, these posts sketch the conceptual foundation of SSI and why it represents a new class of integration operators.

My implementation of the GaussSeidel smoother using a Diagnol direct access scheme in OpenFOAM as compared to the default GS smoother LDU gives almost ~50% improvements in cache misses and hits for a structured 3D cavity tutorial. Profiled using the amazing LIKWID profiler. Will share a deep technical report soon. Check it out and use - https://github.com/amartyadav/DIAGaussSeidel-Smoother-OpenFOAM

Been working on my Linux machine for 3 months now at work - comp. physics, hpc, etc.
Tried working on my MBP yesterday (after around 5 months of not using it for development) - while a superior machine h/w wise, I really couldn't stand macOS.
Linux just works - better even.
