VLIW (Very Long Instruction Word) spent most of the last two decades as a specialist’s tool. After the commercial struggles of general-purpose VLIW designs, with Intel’s Itanium being the canonical...

A step-by-step field guide to building vLLM from source on Ubuntu 26.04, covering Python 3.14 compatibility, CUDA driver issues, and toolchain pitfalls.

How vLLM's op‑level IR reconciles the tension between a compiler target and hand‑tuned kernel dispatch, enabling graph‑level fusion while supporting multiple back‑ends.

If you have a massive compute architecture—whether it’s a modern wide-SIMD vector engine, a Tensor Core array, or a custom deep learning accelerator like a Systolic Array—you face one fundamental p...

In a previous post, we explored the monumental software stack required to run a simple “Hello, World!” program on a modern operating system. But what happens when we apply these concepts to a heter...

In our previous post, we took a deep dive into the hidden complexities of the simplest C program. We discussed how modern Position Independent Executables (PIE) rely on the PLT (Procedure Linkage T...

When you write the absolute simplest C program—one that does nothing but exit successfully—you might expect the compiled output to be trivial. int main() { return 0; } However, executing t...

What is a compiler toolchain? Have you ever wondered what dependencies are required to compile a simple hello-world program? Even a small hello-world program needs a set of header files, and librar...
