If you haven’t see the 7 Questions series interviewing users of #ChapelLang, now is a great time to check it out! The latest post describes how Chapel enabled the rapid development of an interactive data analysis tool that runs on #HPC hardware. Link to series: chapel-lang.org/blog/series/...

Chapel has joined HPSF 🚀👏 Chapel is an open source language for scalable parallel computing, enabling efficient computation across desktops, clusters, & supercomputers. Through HPSF, Chapel will continue to grow as a community-governed project. Learn more: hpsf.io/blog/2025/hp...

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: chapel-lang.org/blog/posts/a...

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

I made a #blog post comparing memory safety across programming languages, with examples! It covers C, C++, Rust, Python, and Chapel. And it discusses memory safety in the context of distributed-memory programming with MPI, Chapel, or OpenSHMEM for #HPC. chapel-lang.org/blog/posts/m...

I’m going to be co-hosting this birds of a feather session at JuliaCon!

Chapel 2.4 is now available! This release brings powerful new features, including multi-dimensional array literals, [significantly improved] Python interoperability, and CMake support. Learn more in its release announcement: chapel-lang.org/blog/posts/a... #HPC #OpenSource

#HPC does it radix sort? I’ve been exploring the productivity and performance of a few distributed memory parallel programming frameworks, check it out at github.com/mppf/distrib... .

How does Chapel stack up against MPI and OpenSHMEM for distributed memory parallel programming? Check out this repo to see implementations and performance measurements of a Least-Significant Digit First Radix Sort in these frameworks. github.com/mppf/distrib... #ChapelLang #MPI #OpenSHMEM

This is about to begin! Recording will be available later.

What is the fastest and easiest to write parallel, distributed radix sort? @mppf.bsky.social has implemented it Chapel, MPI, and OpenSHMEM, github.com/mppf/distrib.... Do you know of other versions or ideas for improving the existing ones? #HPC @chapellanguage.bsky.social @sunitachandra.bsky.social

The Computer Language Benchmarks Game now has results for Chapel 2.3! These charts show Chapel delivering an attractive mix of performance and clear, concise code when compared to languages like Python, Rust, C and Julia. #HPC Browse the CLBG at: benchmarksgame-team.pages.debian.net/benchmarksga...

I’m very excited about the new Chapel Programming Language website. It’s the little things, right? Have a look if you have not already & I hope you like it.

I ❤️ radix sort

A number of us on the Chapel project have been enjoying our interactions on BlueSky these past few months, so we have kicked off a new @chapellanguage.bsky.social account to reflect that. Follow the project there, and thanks to all who make BlueSky a great forum for #HPC conversations!

I recently learned that Dask has some UCX support. Anybody have experience with this? Would love to hear about it!

A mind is a terrible thing to baste

I didn’t know this was possible but the other day I broke a cast iron griddle. Normally it covers two burners on our induction cooktop. I was was cooking something with just one burner on and I turned it up to 11. Turned around to do something, and then there was a loud bang. A big crack appeared!

We’d like to thank everyone who engaged with our team at #SC24, whether at the HPE booth, one of our talks, or chatting with us in the halls about Arkouda and Chapel. Please reach out about any follow-ups, and we look forward to SC25! chapel-lang.org/community.html

Laziness

#SC24 come by the HPE booth to see some of El Capitan & then wander to the other side of the booth to learn about programmability: I’ll demo Arkouda and Chapel!

#SC24 you can find me at the HPE booth tonight demoing Akouda and Chapel!

You otter come to PAW-ATM if you are at #SC24 tomorrow!

I recommend this talk at PAW-ATM! Eric is a great speaker & I look forward to hearing what he says. #SC24

OK, let's try this to show the HPC community already has momentum and can thrive here on Bluesky ... If #HPC or #supercomputing is of interest to you, please interact with this post in some way - either repost, quote, like, reply with insights or just your fav gif, tag friends, etc.
