#2744: Cactus: New cGH entries `cctk_level`, `cctk_block`

Reporter: Erik Schnetter Status: new Milestone: Version: Type: enhancement Priority: major Component: Cactus

Add new `cGH` entries `cctk_level` and `cctk_block`. These complement the existing `cctk_patch` and `cctk_tile_{min,max}` fields, and allow the compute kernels to know on which part of the grid structure they are operating. This is mostly interesting for producing better debugging output.

There are also new `#define`s `CCTK_HAVE_CGH_LEVEL` and `CCTK_HAVE_CGH_BLOCK` to indicate that these new fields are present.
