Any Google Summer of Code 2021 Project Ideas?

Hello Chapel community!

As we have for the past five years, Chapel is looking to submit an application to participate in the Google Summer of Code ( To that end, if any of you have ideas for Chapel projects that students could work on over the summer, we would love to hear them! We have a number of ideas already but are always looking for more. If you suggest an idea, we'll try to find a mentor to carry the idea forward through the summer.

Note that this year the projects need to be smaller to match the smaller time commitment expected by the program.

We need to have an initial list of projects put together by this Thursday (the 18th) for our application. Feel free to respond to this thread, or to message the soon-to-be-created GSoC channel with your ideas!

Thank you for your time,
Lydia Duncan

P.S. For reference, here's a link to last year's project list: Project Ideas List — Chapel GSoC 1.0 documentation
