Avid proponent of making HPC users more productive while making parallel computing more accessible to everyone. Founding member and technical lead of the Chapel Programming Language project (https://chapel-lang.org). Distinguished Technologist at HPE.https://bsky.app/profile/bradcray.bsky.socialhttps://bsky.app/profile/bradcray.bsky.social/post/3msvqhgb4rs2dI'd been really curious to know how Chapel and Arkouda would do on the Trillion Row Challenge (1TRC) out of the box, so really appreciate that Eric was able to do this exploration and write up his experiences amidst his other responsibilities this summer!

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).

If you have thoughts or ideas about sustaining the project, we would be very happy to hear them.
