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...

One of my favorite things about today's release of Chapel 2.9 is its focus on user-requested features and user-reported bugs. While writing up its release announcement, we realized that all new user issues since Chapel 2.8 had been resolved (and many older ones as well).

Chapel Programming Language@chapellanguage.bsky.social · 2mo ago

We’ve released Chapel 2.9 today, featuring improvements to the Mason package manager and its ecosystem, dynamic loading of Chapel libraries, and tools for developing Chapel code, along with many other user-driven features and bug fixes. Read about it at: chapel-lang.org/blog/posts/a...

The latest issue of the Chapel newsletter is out now, featuring updates on Chapel funding, talks, papers, interviews, the website, and more! Check it out at chapel.discourse.group/t/chapel-new...

This is one of my favorite talks from the past few years. If you've got 15 minutes to watch it, I'd be curious for your thoughts and reactions.

Chapel's features for productive scalable parallelism have helped our early adopters accomplish great things (chapel-lang.org/blog/series/...), but we are facing an uncertain future in the year ahead. If you have thoughts or ideas about sustaining the project, we would be very happy to hear them.

I'm excited for Jade Abraham to be representing the Chapel Programming Language project at FOSDEM for the first time in our project's history this week! If you're there, be sure to catch their talk! @fosdem.org @chapellanguage.bsky.social

Chapel Programming Language@chapellanguage.bsky.social · 6mo ago

For the first time, Chapel will be represented at @fosdem.org! If you will be at FOSDEM 2026, make sure to stop by the HPC, Big Data & Data Science track on Sunday and see Jade Abraham talk about Productive Parallel Computing in Chapel and Arkouda. fosdem.org/2026/schedul...

I don't get the chance to talk about Arkouda—a Python library for doing exploratory data analytics interactively on supercomputers—nearly as often as I do Chapel, so this talk at the University of Washington eScience Institute (uwescience.bsky.social) that wrapped up 2025 was a fun one for me.

Chapel Programming Language@chapellanguage.bsky.social · 8mo ago

Interested in doing exploratory analytics interactively on data sets that exceed your workstation’s capacity? Learn about Arkouda, and how it compares to Pandas, Dask, and Spark, in this talk and demo given at the @uwescience.bsky.social Data Science Seminar: www.youtube.com/watch?si=c_o...

Chapel 2.7 is now live! 💙 This release marks an important milestone for the project, as 2.7 is the first version released since Chapel joined the HPSF as an established project in November. Check out all the highlights in our latest blog post: hpsf.io/blog/2025/ch...

I'm looking forward to introducing Arkouda to the UW community tomorrow at the eScience institute's (@uwescience.bsky.social) Data Science Seminar!

Chapel Programming Language@chapellanguage.bsky.social · 8mo ago

For those in the Seattle area, Brad Chamberlain will be speaking at the UW Data Science Seminar tomorrow, Dec 2, introducing Arkouda—the Chapel-based framework supporting interactive data science at scale from Python. For details, see: escience.washington.edu/events/uw-da... uwescience.bsky.social

Congratulations to the Spack team on reaching this significant milestone!

Spack@spackpm.bsky.social · last yr.

💥Spack v1.0 is out!💥 This is a huge milestone. We reworked the core to add compiler dependencies, and we're introducing a stable package API. 🚀1.0 also adds concurrent builds, better includes, and much more -- read it all in the release notes! github.com/spack/spack/...

Are GitHub stars something of a silly metric? In my opinion, "yes." Would I like you to star our project anyway? Also "yes". :)

Chapel Programming Language@chapellanguage.bsky.social · last yr.

We recently received our 1,900th star on GitHub! Thanks to all who’ve shown their support for the Chapel programming language in this way and for helping to grow awareness of our open-source community. Haven’t starred us yet? Help us reach 2k at: github.com/chapel-lang/...

Engin's a great speaker, so you won't want to miss his virtual talk for Los Alamos tomorrow, particularly if you are interested in parallel programming of CPUs, GPUs, and/or supercomputers!

Chapel Programming Language@chapellanguage.bsky.social · last yr.

Can one programming language be used to program multicore processors, GPU-packed supercomputers, and everything in between? Chapel can! Engin Kayraklioglu will give a public talk about Chapel's portability at Los Alamos National Laboratory on June 18th, 10AM PT! teams.microsoft.com/l/meetup-joi...

I made the new scalable sort routine for the Chapel standard library! Now it's possible to easily sort a distributed array just by calling the standard library 'sort'. Outperforms the best distributed Chapel sort to date, and it performs competitively with the KaDiS AMS sort written in MPI. #HPC

Chapel Programming Language@chapellanguage.bsky.social · last yr.

Chapel 2.5 is being released today! Highlights include a new scalable sort routine, an editions feature for experimental breaking changes, a new aliasing reshape() for arrays, initial support for VSCode debugging, dynamically loaded libraries, and more! chapel-lang.org/blog/posts/a...
