The open-source Chapel programming language project is seeking new sources of funding—or other creative ways of sustaining the project—in order to keep the technology going. For details, please see our announcement on the Chapel blog: chapel-lang.org/blog/posts/c...
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.

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.

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...
If you were unable to attend #HPSFCon this month, slides and video for all of the Chapel-related sessions are now online. Topics include GPU programming, techno-social open-source challenges, user stories, tools, benchmarking, a live demo, and more!
