- Scaling test <-> MPI/comm deep dive and profiling (pgrete)
- Updated Copyright notice
- Review non-WIP PRs
A couple small PRs from Andrew - one to update the Triad copyrights and adding a Snow machine configuration to support CTS-1 performance runs.
Joshua Brown has the performance app up and running. Hoping by the end of the week to get performance metrics uploaded for merges and nightly runs.
Carola getting ready to run roofline models on rzansel.
Jonas tried to switch to Kokkos Random - hitting a segfault. Recommend looking at calculate_pi.cpp or update.cpp for packs over meshblocks x variables.
Joshua Dolence got PR in to generalize driver to make it easier to work with downstream.
Ben implemented variable packs for Swarm variables.
Did some performance profiling on multi-GPU runs. Found that we can get better performance with Cuda host-pinned memory. Will discuss more later.
