I have a very basic question about ghost points in Cactus. Is the cctk_lsh contains the size of the local grid with ghost points or not?
Yes. It the the number of points on the local component. You should exclude cctk_nghostzones[i] points from each face of the grid if you want to loop over only interior points. There are macros in cctk_Loop.h to help with this.
