Hacker News with Generative AI: CUDA

Ask HN: Why hasn’t AMD made a viable CUDA alternative? (ycombinator.com)
I appreciate developing ROCm into something competitive with CUDA would require a lot of work, both internally within AMD and with external contributions to the relevant open source libraries.

Parallel Histogram Computation with CUDA (khushi-411.github.io)
The aim of the blog posts is to introduce a parallel histogram pattern, where each output element can be updated by any thread. Therefore, we should coordinate among threads as they update the output value. In this blog post, we will read the introduction about using atomic operations to serialize the updates of each element. Then, we will study an optimization technique: privatization. Let’s dig in!

DeepGEMM: clean and efficient FP8 GEMM kernels with fine-grained scaling (github.com/deepseek-ai)
DeepGEMM is a library designed for clean and efficient FP8 General Matrix Multiplications (GEMMs) with fine-grained scaling, as proposed in DeepSeek-V3. It supports both normal and Mix-of-Experts (MoE) grouped GEMMs. Written in CUDA, the library has no compilation need during installation, by compiling all kernels at runtime using a lightweight Just-In-Time (JIT) module.

CUDA is the incumbent, but is it any good? (modular.com)
Answering the question of whether CUDA is “good” is much trickier than it sounds. Are we talking about its raw performance? Its feature set? Perhaps its broader implications in the world of AI development? Whether CUDA is “good” depends on who you ask and what they need. In this post, we’ll evaluate CUDA from the perspective of the people who use it day-in and day-out—those who work in the GenAI ecosystem:

Check if your performance intuition still works with CUDA (wordsandbuttons.online)
For those of you who don't know what CUDA is, let me explain. Imagine, buses were never invented. There are cars, trains, planes, and motorcycles, just not buses. And one day someone smart asks himself: “wouldn't it be splendid to have cars that would fit a lot of people? One guy could be driving, and all the rest will enjoy the ride.” “Right, like trucks but for people!” “No-no-no, who on earth would ever want to travel by truck?

Initial CUDA Performance Lessons (probablydance.com)
I am somehow very late to learning CUDA. I didn’t even know until recently that CUDA is just C++ with a small amount of extra stuff. If I had known that there is so little friction to learning it, I would have checked it out much earlier. But if you come in with C++ habits, you’ll write suboptimal code, so here are some lessons I had to learn to get things to run fast.
