Here is a small function and the entire program XLA compiled it into: def simp(x): y = (x + 0.0) * 1.0 return jnp.transpose(jnp.transpose(y)) ENTRY %main (x: f32[3,3]) -> f32[3,3] { ...

If you train or serve models, XLA is probably compiling them, whether or not you have ever named it. It is the compiler behind JAX, behind TensorFlow, and — through PyTorch/XLA — behind much of PyT...

The first time I put torch.compile in front of an LLM inference server, it spent the better part of a minute compiling and handed back a 6% speedup. I nearly wrote the feature off. The next morning...

Triton is a compiler with a Python frontend. The @triton.jit decorator does not decorate a function. It parses the function’s AST, runs it through an MLIR pipeline, and emits a GPU binary. The Pyth...

When you compile a CUDA kernel, the final artifact is a cubin — a CUDA binary. It is a standard ELF64 file with NVIDIA-specific sections that encode everything the CUDA driver needs to load and lau...

A survey of code repository hosting in 2026 Most developers do not think about where their Git repository lives until something goes wrong. An account gets suspended. A DMCA notice takes down a pr...

A review and critical analysis of Niklaus Wirth’s foundational text Over the past decade, I have been thinking about how programming languages evolve and what survives the churn. Languages rise an...

A case study of the B200 pipeline model A note on methodology: Everything in this article is based on my analysis of microbenchmarks executed directly on B200 silicon. Nvidia does not publish i...

When building a dataflow analysis framework in a compiler, you quickly encounter an array of mathematical terms: semilattices, semirings, Kleene algebras, Galois connections, and Knaster-Tarski fix...

Training is gradient descent, and gradient descent needs gradients, so every ML framework has an automatic differentiation engine at its core. What is less obvious is that the representation a fram...
