Recently I learned that Jason Turner made a demo of Mull in the "Tool Spotlight" series: youtube.com/watch?v=lhcXAn… Thank you so much, highly appreciated!

Here’s the third part of my blog series on learning LLVM internals. This blog is about JIT compilation using LLVM. sh4dy.com/2024/11/24/lea… Source code : github.com/0xSh4dy/learni…

Ordered a used book online, but received a totally wrong one. Was about to issue return, but turns out this one was published in 1968, so it certainly stays with me

A mathematician enters a bar. The rest of the joke is left as an exercise to the interested reader.

My LLVM Dev Meeting 2024 talk on RISC-V vector and performance tuning in compiler. Cheers! youtu.be/h2tDWoTWUnw?si…

While I implemented this transformation pipeline, seeing it from the end2end perspective is very satisfying

Recently we open sourced our minimalistic AOT Ruby compiler, the goal was to check if the idea behind the compilation makes sense from the performance perspective. It seems it does! So I wrote a short article about the implementation details blog.llvm.org/posts/2024-12-…

If you dont have time to go through a 1000 page book about compilers but you are curious about them you might follow this instead lowlevelbits.org/how-to-learn-c…

Recently, landed my first non-trivial PyTorch PR which adds NVTX annotations for CUDA profiling during training, makes it easier to analyze profiles in a visual and automated way. Should be available in the next version (2.6) 🥳

Just booked my trip to fosdem.org/2025/, anyone coming to Brussels?

I am looking to recruit a PhD student (fully funded at UK home tuition rate) to work on automated testing and verification of machine learning compilers and runtimes! Deadline: 30th April. Please spread the word! Details here: doc.ic.ac.uk/~afd/PhD-Adver…

Started working on another blog post, I don't know if/when I'm going to finish it, but at least I crafted this nice image

Wrote a short technical note on building LLVM plugin using Bazel lowlevelbits.com/p/building-llv…

Are there Senior/Staff+ Engineers on my timeline who want to work on the intersection of Databases, Caches, Infra, K8s/Operators and Scaling Algorithms (think time series, predictive scaling etc)? If so, please drop me a DM. Our small but mighty team is growing!

Wrote a technical note on how to choose the right LLVM/MLIR distribution to build a compiler or a compiler-adjacent tool lowlevelbits.com/p/different-wa…

Recently I had a chance to play with MLIR's Dataflow Analysis Framework. I really love how it is implemented and encourage anyone working with MLIR to get familiar with it. The missing guide to Dataflow Analysis in MLIR open.substack.com/pub/lowlevelbi…

Machine Scheduler in LLVM (Part I) . It's a bit weird I keep writing about scheduling model in LLVM but never really talk about the scheduler itself. So here I am to (finally) close this loop myhsu.xyz/llvm-machine-s…

New blog post: Machine Scheduler in LLVM - Part II myhsu.xyz/llvm-machine-s…

Decided it's time to give a shot to vibe coding, so finally built a thing I've been missing for many years. Currently, only a handful of repos are analyzed, but already found a few cool papers. papergrep.dev
