HVM2 and Bend are officially here!

HVM2 is our new parallel runtime. Over the last few years, we have put enormous effort into polishing the HVM1 prototype, with great emphasis on correctness and stability. As a result, starting today, HVM2 is officially production-ready! We're also releasing a long-promised feature: GPU mode. This is still experimental, but it works, and feels magical.


Bend is a high-level, Python-like, and Haskell-like language that compiles to HVM and, as such, it runs on parallel CPUs and GPUs. For the first time, you're able to interface with HVM in a syntax that is familiar and greatly simplified. This is still not full Python/JavaScript, but it is a small step towards wider language support. Check Bend's guide on its repository to jump straight into action!


HVM2 and Bend are not perfect, and there are still countless limitations and challenges ahead. Running high-level computations in parallel is hard! But we're working hard to absorb this complexity, so you don't need to. As core technologies, HVM2 and Bend unlock many amazing things that weren't possible before. HOC will provide full support to both, and we'll be updating and improving them continuously. Expect exciting releases in the future!
