While HPC hardware has been evolving at a breakneck pace over the past three decades, the languages we use to write HPC code haven’t changed as much. Read @bradcray.bsky.social’s 30-year retrospective, exploring the state of languages for scalable computing: chapel-lang.org/blog/posts/3...
Chapel’s front-end reimplementation, Dyno, has been powering the language’s editor integration. In this HPSFCon presentation, @endofunctor.bsky.social talks about the project’s context, motivation, and goals.

A Python API for Chapel's compiler is at the core of several of the language's tools. On June 4th, @endofunctor.bsky.social will be talking about this API, chapel-py, during our 10am PT deep dive slot. Tune in to learn more!

In this #HPSFCon talk, Engin Kayraklioglu argues that Chapel’s expressive parallelism & locality features not only make users’ lives easier, but also simplify compiler optimizations by providing semantic hints.
