Hi,
I am running the latest release of the Einstein Toolkit with Cactus::presync_mode = "mixed-error". When I add the thorn CarpetMask, the system returns an error: CarpetMask wants sf_info from SphericalSurface, which is not available.
Looking at the scheduler, I can see why this is happening (relevant section):
GROUP MaskBase_SetupMask: Set up the weight function GROUP MaskBase_SetupMaskAll: Set up the weight function CarpetReduce::MaskBase_AllocateMask: [global] Allocate the weight function CarpetReduce::MaskBase_InitMask: [global] [loop-local] Initialise the weight function GROUP SetupIMaskInternal: Set up the integer weight function (schedule other routines in here) CarpetReduce::CoordBase_SetupMask: [global] [loop-local] Set up the outer boundaries of the weight function CarpetReduce::CarpetMaskSetup: [global] [loop-singlemap] Set up the weight function for the restriction regions GROUP SetupIMask: Set up the integer weight function (schedule other routines in here) CarpetMask::CarpetExcludedSetup: [global] [loop-local] Set up the weight function for the excluded regions CarpetMask::CarpetSurfaceSetup: [global] [loop-local] Set up the weight function for the excluded spherical surfaces CarpetReduce::MaskBase_SetMask: [global] [loop-local] Set the weight function GROUP SetupMask: Set up the real weight function (schedule other routines in here) CarpetReduce::MaskBase_TestMask: [global] Test the weight function SphericalSurface::SphericalSurface_Set: [global] Set surface radii to be used for initial setup in other thorns GROUP SphericalSurface_HasBeenSet: Set the spherical surfaces before this group, and use it afterwards SphericalSurface::SphericalSurface_CheckState: [global] Test the state of the spherical surfaces
As you see, CarpetMask is scheduled before SphericalSurface_Set, which is what sets sf_info. This is in the BASEGRID bin.
Since I haven't touched neither CarpetMask nor SphericalSurface, I would think this is a bug, but I maybe I am doing something wrong (I've never used presync_mode before).
I also take the chance to point out two tickets Pedro Espino and I opened but received no attention: https://bitbucket.org/einsteintoolkit/tickets/issues/2487/_evolution_method-... https://bitbucket.org/einsteintoolkit/tickets/issues/2484/lack-of-convergenc...
Best, Gabriele
