present: Erik, Roland, Steve, Lucas, Cheng-Hsin, Philipp, Jay, Liwei, Yosef, Allen
Z4c ===
* not included in the ET * test cases that exist rely on other thorns not in the ET, eg qc0 which needs TwoPunctures * want simpler test cases to include in ET
updates *******
Steve & Lucas =============
* globalderivatives are making progress * has re-implemented MP projections, which were responsible for bugs seen before * found issues when working with Zach and is now testing 1st and 2nd order derivatives * would like to go back testing bbh simulations using the hybrid Runge-Kutta evolution schemes, Liwei is requesting access to mike to test
Yosef & Liwei =============
* currently finds large values of computed Hamiltonian constraints in Z4c(ow) * would need way to read in 3D output files as initial data using FileReader functionality, Erik says that this is implemented in CarpetX * pull requests for CarpetX / Derivs should be reviewed * discussed use of schedule.hxx functionality to implement traversal of schedule / calling scheduled functions used in ReadInterpolateX * Erik and Liwei discussed design of ReadInterpolateX thorn and ways to implement this functionality by having Carpet write out the data instead of CarpetX reading them in
Allen =====
* porting Hydro analysis thorns from Carpet to CarpetX * Roland suggests using the AnyVector branch, might have issues with checkpoint / recovery but could also be Roland's use of Python interface to OpenPMD
Jay ===
* working on c2p for GPUs
Erik ====
* is debugging issues with checkpoint / recovery * Roland mentions issue with openpmd seen by Maxwell Rizzo when testing on Anvil
