gallery examples ================

* still lacking updates for BBH gallery example for 2025_05 and 2024_11

gcc15 failures ==============

* Zach suggested to compile ET with newest flavor of compilers regularly * Roland mentions that we could have a weekly build using the new compiler using github, Ubuntu 25.04 has gcc15, Zach suggests there may even be a gcc-latest or so image

Benchmarking GRHayLHD simulations =================================

* Wei, Zach and Leo discussed results of benchmarking a GRHayLHD simulation for optimal speed varying ranks and threads * tests were done on NERSC Perlmutter (CPU only) * suggest to try both with and without IO enabled * suggest to check mpirun options to have correct affinity to cores / numa-nodes etc.

Yours, Roland
