Would there be someone willing to step up and lead the discussion in case I am not around at 9am? Yours, Roland -- My email is as private as my paper mail.

This is intended to give those who are familiar with Carpet's NewRad an understanding of how to use NewRadX. So some familiarity with how the raditiative boundary condition is formulated is required.

Steve reviewer. * Allen may propose inclusion of PunctureTracker and ApparentHorizonFinderDirect. Will leave out QuasiLocalMeasures for now since it requires hacks due to Fortran and complex valued grid variables. ** Roland mentioned that the driver specific changes to Multipole should be isolated to a small section of the the code that constructs the test data. Would be good to have single code that supports both drivers (easier to maintain) ** Jay has been using NewRadX with Z4c on Frontier, this worked on GPUs ** Alex suggested that someone at RIT who used NewRadX may be a good person to review, ** Roland mentioned that tests for release will start May 3rd so all reviews must have (positively) finished by then ** Jay will focus on finish the AsterX paper and AsterX will be proposed for inclusion afterwards so that documentation can be written CarpetX testing and development: * Erik is currently testing a qc0 setup and would like to use a common setup for the different codes to compare them more directly. Cheng-Hsin will upload the parameter file for grazing collisions that he used with LeanBSSNMoLX to the CarpetX wiki. ** Jay asked about a speed benchmark of Z4c vs. other codes, right now this does not exist. Newer versions of CarpetX make this easier though by outputting performance data. * Steve and Sam have been looking at CarpetX + NRPy+ ** Sam ran into hard-coded limit on number of grid functions per grid function group, will update limit in CarpetX source code * Lucas and Erik are working on Multipatch code, currently doing some debugging. * Lucas made CarpetX documentation TeX files compatible with online documentation system, so they now show up on einsteintoolkit.org AsterX: * Jay is making steady progress on the paper * working with Samuel Tootle on FUKA reader * want paper out ASAP CanudaX: * Cheng-Hsin has been debugging NPScalarX and in doing so found some race condition in the older NPScalar code * currently still sees some differences but only in the boundaries so could be due to different boundary location in Carpet / CarpetX Runge Kutta prolongation: * discussed Liwei's current status of code * required changes can all do done in "user" code and do not require changes to CarpetX itself * suggestion is to implement a standalone RK4 time stepper code for this and not use ODESolvers for now * will need full grid functions for Y1, Y2, Y3, Y4 just for prolongation -- My email is as private as my paper mail.
