Radiant Computer (@radiant.computer)

Work has started on the Radiant Kernel. * It’s an exokernel. Very minimal. * It uses ring buffers as the only syscall interface (think io_uring). * There is no virtual memory — protection works via static analysis. * There are no device drivers, software has direct hardware access.

Radiance compiles itself in 0.2s from scratch on the experimental amd64 backend. It's fast 💨

Some of these compilers have a substantial fixed overhead, so a larger source code was used to make things more fair. The LOC/s is what counts.

Also note that most of these compilers are optimized for incremental compilation. Radiance is optimized for whole program compilation. The only other language we know of that by design does not do incremental compilation is Jai.

All benchmarks are run on a single thread. Radiance compiles its own source code, while the other compilers are compiling synthetic code. When allowed to use multiple cores, Go was the fastest. Radiance isn't optimized for parallelism currently.

A discussion forum?

Radiant is open-sourcing its compiler toolchain and launching code.radiant.computer today.

The release includes `forge`, a simple read-only Git forge that supports SHA-256 repositories, and HTTPS cloning. Forge was entirely vibe-coded. Let us know if you encounter any issues with it.

To learn more about the Radiance compiler, see the last few posts on our log: radiant.computer/log/ If you're interested in personal computing or language design, please reach out, we'd love to talk.

The Radiance language is still in an early stage, but the compiler is already self-hosting. The compiler sits at around 18 KLOC. It has zero dependencies, meaning that it links and emits machine code directly. It also includes an intermediate language.

Radiance is not meant to be used outside of the Radiant system, at least for now. It requires a RISC-V emulator to run, and does not emit ELF-compatible binaries. It was designed to be small like C, but ergonomic like Rust. We're getting there. The compiler and emulator are MIT licensed.

The Radiance compiler has reached a fixed point. This means it can now compile itself and generate identical output to itself.

I'm working on a new kind of computer. It's called the Radiant. I've been dissatisfied with the state of personal computing for many years now, so it's time I did something about it. If you think computers could be so much better than what they are, this is for you. radiant.computer
