#2892: SpacetimeX: GPU error in PunctureTracker::PunctureContainer::interpolate

Reporter: Miren Radia Status: open Milestone: Version: development version Type: bug Priority: major Component: CarpetX

Comment (by Miren Radia):

That parameter file with `CarpetX::poison_undefined_value = yes` works fine for me since it doesn’t use the PunctureTracker thorn.

The problems arise when I enable the `PunctureTracker` thorn (and also `BoxInBox` since it’s required by `PunctureTracker`). I modified the previous parameter file (i.e. `qc0.par` with `CarpetX::poison_undefined_value = yes`) by enabling those two thorns and adding the following parameters:

``` BoxInBox::num_regions = 1 BoxInBox::shape_1 = "cube" BoxInBox::num_levels_1 = 1 BoxInBox::radius_1 = [-1] BoxInBox::position_x_1 = 0.0 BoxInBox::position_y_1 = 0.0 BoxInBox::position_z_1 = 0.0

PunctureTracker::verbose = yes

PunctureTracker::track [0] = yes PunctureTracker::initial_x[0] = +0.5843214365

PunctureTracker::track [1] = yes PunctureTracker::initial_x[1] = -0.5843214365 ```

I then get the following error (which I mentioned in my original issue description):

``` ERROR from host tu-c0r0n87 process 0 in thorn CarpetX, file /mnt/lustre/tursafs1/home/dp415/dp415/dc-radi1/ETK/Cactus-CarpetX-main/arrangements/CarpetX/CarpetX/src/valid.cxx:552: -> CallFunction iteration 0 PunctureTracker_SetupGroup: PunctureTracker::PunctureTracker_Setup checking output: Grid array "BOXINBOX::position_x[0]" has 1 nans on time level 0; expected valid The interior is valid because: CallFunction iteration 0 PunctureTracker_SetupGroup: PunctureTracker::PunctureTracker_Setup: Mark output variables as valid.
