This is my last week at @NVIDIA.
It's been an honor and a pleasure to be a part of this incredible team.
I couldn't have asked for a better job these last 9 years.
🫡
I joined @nvidia nine years ago today, against the advice of a colleague who said their comp was below market.
But I really believed in the mission and the people, so I went.
I met @__simt__, Michael Garland, and Jared Hoberock on the C++ committee. I thought they were the smartest people there.
I worked at @BerkeleyLab on concurrent and parallel programming paradigms, mostly for SIMD.
@__simt__ convinced me that SIMT was a superior model for parallelism.
He sold me on a revolutionary new GPU architecture where threads would independently scheduled: Volta, the basis of all modern GPUs.
I asked him three times to find me a place at @nvidia. The first two times, he wasn't sure where to place me or if I'd like it.
The third time, he had me come in to talk to Chris Lamb (now VP of CUDA). We chatted for two hours and he outlined the role he believed modern C++ would play in CUDA.
I came back for an 8 round interview panel. All of the questions were answered with std::atomic. No one was sure what I would be working on.
I, a modern C++ person, was placed in the CUDA driver org, which was written almost entirely in C.
On my first day, my manager told me I'd be responsible for Thrust and CUB, @nvidia's first two open source libraries. No one had worked on them for a while and there was no product manager. I'd have to do it all.
I put together a roadmap and got the libraries back on GitHub. I started sending status updates from CCCL, the CUDA Core Compute Libraries team, which did not exist. Eventually, they let me hire three people to fill out the team.
We built libcu++ and abstractions for all the quirky new features being added to our chips to support these AI workloads that seemed to be growing in importance rapidly.
After a few years I was asked switch orgs and guide the roadmap for our HPC C++ compiler. Programming languages and models quickly became my role, from stdpar to CUDA-Q to CUDA Python to CUDA Tile to autoresearch.
What a ride it's been!

Any startup interested in HPC engineer who worked on 2 open architectures and has experience debugging model behavior? Almost 3 but I turned down the job for [redacted] reason. Also llama.cpp maintainer / infra runner on Gemini protocol.
I need to find myself a new job.

Looking for a killer FDE in Sydney to join Amp. Hit me up!
We’re also open to hiring a pair.

I would like to announce that I'm starting a new role at OpenAI.
I'm not but I'd like to be able to announce it.

Bend 2 is here!
It is a new programming language that blocks AI mistakes via *proof checking* - the same technique big AI labs used to solve open math problems, like Navier-Stokes.
It is also very fast, and runs on GPUs.
Watch the video. Link in the comments.
RELEASE DAY
After almost 10 years of hard work, tireless research, and a dive deep into the kernels of computer science, I finally realized a dream: running a high-level language on GPUs. And I'm giving it to the world!
Bend compiles modern programming features, including:
- Lambdas with full closure support
- Unrestricted recursion and loops
- Fast object allocations of all kinds
- Folds, ADTs, continuations and much more
To HVM2, a new runtime capable of spreading that workload across 1000's of cores, in a thread-safe, low-overhead fashion. As a result, we finally have a true high-level language that runs natively on GPUs!
Here's a quick demo:

I'm looking for my next role, in Montreal or remote! My background spans compilers, systems, and AI research.
I'd welcome introductions, leads, or a repost to help spread the word ❤️

Donald Trump invented the transformer architecture. You might disagree. You might even have evidence to the contrary. But you have to ask yourself: is this really worth losing my frontier AI research lab over? Donald Trump invented the transformer architecture.

My dad has been working at TSMC as an engineer for the last 20 years, and he’s been in semiconductors as a whole for the past 30. A few days ago, he gave me one of the textbooks he’s referenced from when he was working at SK Hynix as a design engineer in the late 90’s.
The book (published in 1997) everything to do with CMOS circuit design and simulation, and what I find interesting is that the fundamental math and physics behind it has not changed in the last 30 years. What really has changed, is the simulation technology behind circuit verification that has evolved in the last 50 years, all the way from when SPICE v1 was released in the 70s, to whatever we have now.
It really does feel cool to be working on the next iteration of a technology that has been around for so long, yet is so difficult to use and develop even now.
I just think semiconductors and simulation is so interesting. I’m really happy that I get to work on this full time with my own startup, with others who also believe in the vision.

Does it ever get easier? Every year seems to get harder. Challenges I could have never have conceived of facing. I could have never predicted that so soon we'd see a year of lockdown, AI, or culture continue to rot.
All of those are easy enough to manage though. What's even harder to predict is how your own life can change instantly. I never thought a car running red light would land me unable to write code. There's something I think very few self help books talk about and that is what happens when your very ability to reason, make decisions, and execute fails. These books cannot and will not help you if you have had a concussion. They especially won't help you if you have severe seizures and you blame your inability to think during one as laziness. Atomic habits will not save you.
The brain cannot and will not heal. People who say otherwise don't understand neuroscience. But there is a workaround, the brain can repurpose non damaged parts of the brain. It also can rewire itself. So how do you do that? Nobody really has a guidebook. There is no research paper I or grok can find with a magic protocol (sorry Dr. Huberman).
So I'm faced with two choices. I can either accept that I will never be able to work a job again and mooch off everyone playing "chronically ill victim." Reddit's r/chronicillnness is full of that. Or I can attempt to retrain my brain to code. That is why I did the ARM64 assembly livestream without AI. And more will come.
I will climb out of this hole. Just like we cannot predict the bad things that will happen we also cannot predict the good things that will happen. It is quite possible next month or even 2027 will be the best year of my life. But the only way to have good things happen to you is to stack the odds in your favor. You have to roll the dice a ton. Rn i've gotten a lot of bad rolls, but that is not going to stop me from rolling the dice even more.

We present our work on a new cryptographic primitive:
"Two-limb CRT Ring-LWE encryption with exact decryption and public re-randomization" - Journal of Cryptographic Engineering (2026)
It enables:
- post-quantum encryption
- public rerandomisation with constant size ciphertext
Encrypt data.
Anyone (without the key) can turn the ciphertext into a fresh-looking one, billions of times. Still decrypts perfectly.
Our new mobile-friendly post-quantum primitive is the first step toward making border crossings safer for journalists.
