Present: Eric, Helvi, Peter, Roland, Sam, Steve, Zach
Neutron star star: * Zach provided details on HARM3D evolution, currently no NR yet, but development on multiple fronts * provided update on Vassili's SpherecalBSNN and SphericalGRMHD codes that will be made public sometime after September * Steve mentioned LSU code (Octotiger) that seems to do better at preserving angular momentum than plain Cartesian codes
Alternative drivers for the ET: * had a discussion about alternative drivers * would want interaction with developers * Steve mentioned octotiger, developed at LSU, using HPX, currently ran on full scale on Pizdaint * Zach mentioned the DendroGR code, as something to consider as well (David Nelisen's code at RIT). Still in development, will have subcycling in time by end of summer. * Roland mentioned AMReX, which is a block structured AMR code similar to CarpetLib so "easy" to adapt. Has funding from DOE as part of ExaScale computing project * would have to be made of part of a larger story
Peter's self-force code: * almost completely done with rewrite, started to write code paper * code to be public at some point after that, timeline is weeks and months, but have to specific deadline * will need to go through review, volunteers needed
Yours, Roland
