Deadline extended! Second Workshop on Correctness and Reproducibility for Earth System Software & R3Sw Tutorial

October 21, 2025

Register now for the 2nd Workshop on Correctness and Reproducibility for Earth System Software. This workshop will be held in conjunction with the tutorial, “Rigor and Reasoning in Scientific Software (R3Sw).”

Deadline for in-person registration extended until this Friday! You can now register by this Friday, October 24 for in-person registration ($80), or by Friday, October 31 for virtual registration ($25).

The workshop and tutorial will take place Wednesday, November 5, through Friday, November 7 at NSF NCAR’s Mesa Laboratory in Boulder, Colorado and virtually. The R3Sw Tutorial runs primarily on Day 1 (Wednesday, November 5), with optional sessions on Days 2 to 3.

This workshop aims to provide a venue to discuss challenges, opportunities, and recent advances in ensuring software correctness and reproducibility for climate and weather modelers, HPC community members, and industry partners. The hands-on tutorial will cover core topics such as unit testing, continuous integration (CI), property-based testing, software design for testability, and reasoning in research software. 

See the event website for more information, including the tentative program for the complete three-day schedule that includes tutorial sessions, panel discussion, invited and contributed talks. This event is sponsored by the 2025 Better Scientific Software (BSSw) Fellowship program.
