Meeting Minutes for 2025-04-17
by Lucas Timotheo Sanches 17 Apr '25

17 Apr '25

Present: Lucas T. Snches (Minutes), Steven R. Brandt, Roland Hass, Zacharia Etienne, Leo Rosa Werneck (Chair), Deborah Ferguson. # Upcoming ET Release - z4c: No test cases yet. - BHaHAHA: Peter is unavailable for review due to medical reasons. This means that the inclusion of this code may have to be delayed. - CCE: Lucas reports being OK with the inclusion so far. Test cases and documentation are missing, but Deborah reports to be working on it. The deadline for the final review and inclusion was set next week (04/24/2025). - FLRW Solver: Zach reports that he performed an initial review and Hayley responded very quickly. First round of feedback and fixes are done and Zach wants to give the code another pass. He reports that it will be possible to give the final review vote next week (04/24/2025). # ET US Summer School, Austin TX, June 9-13 2025 - Pablo sent invitations to speak for all speakers. - Zach reports that during the recent PI meeting, Pablo shared detailed updates of the summer school. Everything is going well. Zach's understanding is that If every invited speaker gives a talk, there may not be time for any contributed talks. If not, there will probably be invited talks. # Unanswered questions on mailing list No questions # Open tickets sorted by update time - 2861: Lucas reports being unable to answer the reporter's latest questions in the last few days due to paper submission deadlines and a conference. He says that he will continue answering the ticket. - 2856: Steve reports having addressed all comments. Roland points out that the code only triggers under specific conditions, which Steve reports as being correct and intended. Roland asked for Steve to resolve conversations in the GitHub page and to report that the behaviour as is is acknowledged and intended in writing for accounting purposes. - 2052: Steve says that he looked at it, but he still needs more time to fix it # Tickets ready for review - 2855: Lucas reports waiting for input on how to read variables from parameter files without bypassing the READS/WRITES mechanism of schedule.ccl files. Roland provided information on a set of Driver functions that can be used to notify the Driver that data has been changed. Lucas reports that he will look into these and update the thorn accordingly.

Present: Roland, Peter, Steve, Zach, Deborah, Johnny, Keith, Leo ET release ========== * no updates on Z4c * Deborah is working through Lucas' comments on CCE * Zach is reviewing FLRWSolver * Peter will start reviewing ET summer school ================ * no updates yet Other items =========== * Zach pointed out that AHFinderDirect's docs and paper all suggest to use Hermite interpolation, but the ET mostly uses Lagrange. Zach finds faster horizon finding times with Hermite, possibly due to less noise due to the better interpolator Yours, Roland -- My email is as private as my paper mail. I therefore support encrypting and signing email messages. Get my PGP key from http://pgp.mit.edu .
