Show HN: Luminal – Open-source, search-based GPU compiler (❄️ Score: 150+ in 5 days)
Link: https://readhacker.news/s/6A3K9
Comments: https://readhacker.news/c/6A3K9
Hi HN, I’m Joe. My friends Matthew, Jake and I are building Luminal (https://luminalai.com/), a GPU compiler for automatically generating fast GPU kernels for AI models. It uses search-based compilation to achieve high performance.
We take high level model code, like you'd have in PyTorch, and generate very fast GPU code. We do that without using LLMs or AI - rather, we pose it as a search problem. Our compiler builds a search space, generates millions of possible kernels, and then searches through it to minimize runtime.
You can try out a demo in `demos/matmul` on mac to see how Luminal takes a naive operation, represented in our IR of 12 simple operations, and compiles it to an optimized, tensor-core enabled Metal kernel. Here’s a video showing how: https://youtu.be/P2oNR8zxSAA
Our approach differs significantly from traditional ML libraries in that we ahead-of-time compile everything, generate a large search space of logically-equivalent kernels, and search through it to find the fastest kernels. This allows us to leverage the Bitter Lesson to discover complex optimizations like Flash Attention entirely automatically without needing manual heuristics. The best rule is no rule, the best heuristic is no heuristic, just search everything.
We’re working on bringing CUDA support up to parity with Metal, adding more flexibility to the search space, adding full-model examples (like Llama), and adding very exotic hardware backends.
We aim to radically simplify the ML ecosystem while improving performance and hardware utilization. Please check out our repo: https://github.com/luminal-ai/luminal and I’d love to hear your thoughts!

Show HN: Sping – An HTTP/TCP latency tool that's easy on the eye (Score: 150+ in 14 hours)
Link: https://readhacker.news/s/6AiiV
Comments: https://readhacker.news/c/6AiiV
I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues.
The two best things about it are:
- It's easy to install if I can access pip in the container
- It makes a compelling screenshot (which helps me communicate with coworkers.)
With those two lessons in mind: Here is Sping!
Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS)
Two good things about it:
- It's easy to install if you have pip. (Available at [service-ping-sping](https://pypi.org/project/service-ping-sping/) on PyPi)
- It makes a compelling screenshot.
Not sure if this is the kind of thing that anyone else would be interested in. But I've enjoyed making it and intend to keep using it.

Show HN: Base, an SQLite database editor for macOS (🔥 Score: 154+ in 2 hours)
Link: https://readhacker.news/s/6AjZM
Comments: https://readhacker.news/c/6AjZM
I recently released v3 of Base, my SQLite editor for macOS.
The goal of this app is to provide a comfortable native GUI for SQLite, without it turning into a massive IDE-style app.
The coolest features are
- That it can handle full altering of tables, which is quite finicky to do manually with SQLite.
- It has a more detailed display of column constraints than most editors. Each constraint is shown as an icon if active, with full details available on clicking the icon.
This update also adds support for attaching databases, which is a bit fiddly with macOS sandboxing.
I'd love to hear any feedback or answer any questions.
