> I also wonder if internally Linux is used for development of the platform itself

Developers at Oxide work on whatever platform they'd like, as long as they can do their work. I will say I am in the minority as a Windows user though, most are on some form of Unix.

So one of the reasons why Rust is such an advantage for us is its strong cross-platform support: you can run a simulated version of the control plane on Mac, Linux, and Illumos, without a physical rack. The non-simulated version must run on Helios. [1]

That said we do have a rack in the office (literally named dogfood) that employees can use for various things if they wish.

Interesting thanks for the insight.

Now i'm imagining Helios inside WSI - Windows Subsystem for illumos

You're welcome. I will give you one more fun anecdote here: when I came to Oxide, nobody in my corner of the company was using Windows. And hubris and humility almost Just Worked: we had one build system issue that was using strings instead of the path APIs, but as soon as I fixed those, it all worked. bcantrill remarked that if you had gone back in time and told him long ago that some of his code would Just Work on Windows, he would have called you a liar, and it's one of the things that validates our decisions to go with Rust over C as the default language for development inside Oxide.

That would be pretty funny, ha! IIRC something about simulated omicron doesn't work inside WSL, but since I don't work on it actively, I haven't bothered to try and patch that up. I think I tried one time, I don't remember specifically what the issue was, as I don't generally use WSL for development, so it's a bit foreign to me as well.

> that was using strings instead of the path API

Man you can't let Brain live that one down can you?

I didn't bother to git blame the code, I myself do this from time to time :)

I mean... WSL2 is just hyperv with some integration glue, and illumos isn't Linux but unix is unix; that might well be doable.

How is Oxide for GPU-heavy workloads?

There are no GPUs in the rack, so pretty bad, haha.

We certainly understand that there's space in the market for a GPU-focused product, but that's a different one than the one we're starting the company off with. There's additional challenge with how we as a company desire openness, and GPUs are incredibly proprietary. We'll see what the future brings. Luckily for us many people still desire good old classic CPU compute.

Would pass-through to VM work?

At $work I'm running SmartOS servers with GPU passing to a ubuntu bhyve for the occasional CUDA compute and it works wonderfully. Wonder if similar could be possible with Helios?

The software interface isn't the problem: the problem is that there are no physical GPUs in the product. There's nothing to pass through.
