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:

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!

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.

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!

Rust has stronger safety than Chapel overall. That is covered in the initial + - table.

Re use-after-free and unsafe blocks, I’ve heard of parallel programmers using ‘unsafe’ everywhere. Maybe they are doing it wrong. Even so, one should not assume that Rust completely removes the issue.

I’m the author of the article.

Of course C++ and Rust have very different safety properties. These icons are summary information & the article defines what each means. Rust programmers still deal with unsafe code (possibly in libraries) and still need to be aware of use-after-free being an issue.

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.

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

Chapel Programming Language @chapellanguage.bsky.social · Apr 9

Attending JuliaCon this year? Join us at the “Chapel ❤️ Julia” session!

Chapel and Julia have similar goals despite big differences in approach. Join this BoF for a brief overview of Chapel and a discussion where the two communities can learn from each other.

#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.

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

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.

Chapel Programming Language @chapellanguage.bsky.social · Feb 24

We've made some big changes to our website! It shows off the power of Chapel with a modern, smartphone-friendly appearance. Check out all the awesome projects people are using Chapel for today: chapel-lang.org
