In this month's edition of "10 Myths of Scalable Parallel Programming Languages", Brad focuses on the question of the adoptability of new parallel languages and the extent to which extending an existing language might help vs. not.

Looking to share your work using Chapel? Look no further. The ChapelCon '25 Call for Papers is live! Submissions open June 27th and close July 25th. We're excited to see what you've been working on! http://www.wikicfp.com/cfp/servlet/event.showcfp?eventid=188767
This month's 2.5 release introduced Chapel editions, inspired by Rust. This allows the language to continue to evolve by introducing breaking changes, without requiring users to update their code for such changes immediately.
For details, see: https://chapel-lang.org/blog/posts/announcing-chapel-2.5/#chapel-editions
Chapel 2.5 adds a fast new distributed sort implementation to the standard library! It out-scales other distributed Chapel sorts. To use it, pass a Block-distributed array to the standard sort() procedure.
See the Chapel 2.5 release notes for more information:

HPE Discover has started! If you are attending and interested in learning more about Chapel and Arkouda, visit our demo station in the Showcase!
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 at 10AM PT!
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'. It even outperforms the best distributed Chapel sort to date, and it performs competitively with the KaDiS AMS sort written in MPI. There are more details in the release announcement linked below.

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!
It’s been a while since our last live demo on GPU programming with Chapel—join us Thursday, June 12th at 10 AM Pacific Time (US) for a fresh look! We will discuss how Chapel’s first-class parallelism and locality support makes it a breeze to program multi-GPU, multilocale systems!
@SnoopJ@hachyderm.io I have 10% of an HTTP server written in #chapelLang up on my codeberg. One day...
@SnoopJ@hachyderm.io if memory serves, a goal of #chapelLang was to have Python-esque syntax ("as easy as Python") and while it's hardly a 1 to 1 clone of Python, I think the syntax (and aesthetics) of Chapel are really, really good, because I think they explicitly cared about similar stuff in this case.
Chapel developers Daniel and Jade will be at the HPE booth at ISC25 in Hamburg, Germany, June 8th-12th. Stop by to learn about Arkouda, a framework for interactive, large-scale data analysis, and about how the Chapel language makes it possible!
Did you know that you can use an LLM system to generate a working, parallel Chapel program? Learn about how Chapel can be used with various LLM-enabled tools to accelerate development in the demo on Thursday, June 5th at 10am PT. We hope to see you there!
In this month’s edition of “10 Myths About Scalable Parallel Programming Languages (redux)“, Brad Chamberlain takes on the myth that new parallel programming languages can’t succeed because so many previous ones have failed.
Next Tuesday at the 30th HIPS workshop at IPDPS , Brad Chamberlain will be presenting the keynote, entitled “Reflections on 30 years of HPC programming: So many hardware advances, so little adoption of new languages.” Hope to see you there!
Chapel’s May newsletter is out now! Check it out for news about many recent and upcoming talks, new public project meetings, as well as Chapel events at JuliaCon, ISC, and HPE Discover!
Chapel’s new compiler front-end rework, which has brought new language tooling and better error messages, has seen much progress recently. Learn more about this effort, including its goals and design, in the demo session on Thursday, May 22nd at 10am PT! 🚀
Have a cool Chapel demo or a question for Chapel developers? Want to see first-hand how development of this open-source language happens? Then consider attending the Chapel weekly project meeting on Tuesdays at 10am PT, open to all who are interested.
