The messy reality of SIMD (vector) functions
We’ve discussed SIMD and vectorization extensively on this blog, and it was only a matter of time before SIMD (or vector) functions came up. In this post, we explore what SIMD functions are, when they are useful, and how to declare and use them effectively. A SIMD function is a function that processes more than… Read

Serving 200M requests per day with a CGI-bin
In the early 2000s, we used to write a lot of CGI programs. This was the primary way to make websites dynamic at the time. These CGI programs were usually written in Perl, but sometimes in C to increase performance. The CGI mechanism is conceptually simple but powerful. When the web server receives an incoming request…

Caching is an abstraction, not an optimization
I've always been told that caching is a tool to make software faster. That, given some careful considerations to consistency, caching makes it so that when...

The Evolution of Caching Libraries in Go
For the last few years, I've been developing caching library, and today I'd like to talk about the evolution of caches in Go and where we stand today. Especially since Go 1.24 was officially supposed to focus on caching improvements, but I haven't heard much news about them - time to fix that .

Life of an inference request (vLLM V1): How LLMs are served efficiently at scale
vLLM is an open-source inference engine that serves large language models. We deploy vLLM across GPUs and load open weight models like Llama 4 into it. vLLM sits at the intersection of AI and systems programming, so we thought that diving into its details might interest our readers.

How much slower is random access, really?
You may know that, because your computer has different caches (L1, L2, L3...), and memory operations operate on cache lines of about 64 bytes each, you should write programs that exhibit locality to get maximum performance.

Making TRAMP faster
I recently changed jobs and found myself in a position where I would need to do a lot of work on remote machines. Since I am Emacs user, the most common way to do this is using TRAMP (Transparent Remote access, Multiple Protcol). TRAMP is an Emacs package that let’s you treat a remote host like a local system, similar…

Compiling LLMs into a MegaKernel: A path to low-latency inference
TL;DR: We developed a compiler that automatically transforms LLM inference into a single megakernel — a fused GPU kernel that performs…

The unreasonable effectiveness of fuzzing for porting programs
A simple strategy of having LLMs write fuzz tests and build up a port in topological order seems effective at automating porting from C to Rust.

SIMD-friendly algorithms for substring searching (2016)
Popular programming languages provide methods or functions which locate a substring in a given string. In C it is the function strstr , the C++ class std::string has the method find , Python's string has methods pos and index , and so on, so forth. All these APIs were designed for one-shot searches . During past…

Jemalloc Postmortem
The jemalloc memory allocator was first conceived in early 2004, and hasbeen in public use for about 20 years now. Thanks to the nature of open source software licensing,jemalloc will remain publicly available indefinitely. But active upstream development has come to anend. This post briefly desc...

macOS Tahoe brings a new disk image format
ASIF disk images are new in Tahoe, and promise to be space efficient, as they’re sparse files, and almost as fast as the disk they’re stored on. Ideal for VMs and general use.

It's the end of observability as we know it (and I feel fine)
In a really broad sense, the history of observability tools over the past couple of decades have been about a pretty simple concept: how do we make terabytes of heterogeneous telemetry data comprehensible to human beings? We’ve seen different companies tackle this in different ways for technology like Ruby on Rails…
