#2922: CarpetX does not compile with CUDA 12.9 Reporter: Steven R. Brandt Status: new Milestone: ET_2026_05 Version: Type: bug Priority: major Component: CarpetX Comment (by Roland Haas): This seems to actually have been due to newer compilers pulling in C++23 stdc++ library files, which push more names into the `std` namespace. Pull request https://github.com/EinsteinToolkit/CarpetX/pull/381 addresses this and resolves this ticket as well. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2922/carpetx-does-not-…

#2949: use c99 bool instead of typedefing our own Reporter: Roland Haas Status: new Milestone: Version: Type: bug Priority: minor Component: C23 makes `bool` a reserved keyword and provides the type by default making some thorns (and the flesh) fail to compiled. These three pull requests add the required `#include <stdbool.h>` to the respective files. Since this exists in c99, which Cactus requires, this is fine. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2949/use-c99-bool-inst…

#2948: HydroBaseX: Missing HydroBase features (Aphi GF, conditional storage, split init)
by Maxwell Rizzo 22 May '26

#2948: HydroBaseX: Missing HydroBase features (Aphi GF, conditional storage, split init) Reporter: Maxwell Rizzo Status: new Milestone: Version: Type: bug Priority: minor Component: CarpetX Current HydroBaseX has a single routine that zeros all the variables it declares, along with a single parameter controlling whether this routine runs: `initial_hydro`. This parameter was used/extended by initial data thorns when they provide hydro quantities. Following the legacy Carpet/HydroBase convention, `initial_hydro` should only control the minimal hydro fields, with other GFs accompanied by corresponding `initial_*` parameters and routines. The current implementation works, but is awkward for initial hydro data thorns to integrate with: they can either avoid using `initial_hydro` themselves and let HydroBaseX zero all fields and place their data ontop of that, or they can manually zero the fields they are not providing, which is unnecessary when HydroBaseX should be able to do it. Additionally, HydroBaseX is missing the `Aphi` GF. This is the electric potential, and adding it would round out the EM support alongside `Bvec` and `Avec`. Lastly, modularizing this initialization should allow conditional storage to be restored, storing optional hydro fields only when the corresponding `initial_*` parameter is not `"none"`, following HydroBase. This should also provide a minor memory/performance improvement. Addressed by already open PR: [#385](https://github.com/EinsteinToolkit/CarpetX/pull/385) -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2948/hydrobasex-missin…

#2947: CarpetX: Support 2D output
by Maxwell Rizzo 21 May '26

21 May '26

#2947: CarpetX: Support 2D output Reporter: Maxwell Rizzo Status: new Milestone: Version: Type: enhancement Priority: minor Component: Changes (by Maxwell Rizzo): Currently 1D slices (x/y/z) and the full 3D output for Grid Functions are both supported output configurations from CarpetX. CarpetX is missing functionality to output GFs sliced along 2D planes (xy, xz, yz). There is a sublety for how the slice is chosen, given the different centering options, some variables likely will not contain data along the `x/y/z=0` planes exactly, which is a similar sublety that the 1D output slice must resolve, hopefully these can be resolved consistently. Also from a discussion with Roland, 2D output is inefficient for a Carpet/CarpetX simulation to output, compared to 1D and 3D. A performance test could be useful in gauging if this feature would be worth implementing/using at all in CarpetX. TSV (or another text file format) probably makes sense as the starting point, if functional a compressed format like OpenPMD would also be desirable, bringing the 2D CarpetX output features in-line to what was present in Carpet. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2947/carpetx-support-2…
