A driver consists of a GH extension, and the following overloaded functions.

  1. CCTK_EnableGroupStorage
  2. CCTK_DisableGroupStorage
  3. CCTK_ArrayGroupSizeB
  4. CCTK_QueryGroupStorageB
  5. CCTK_SyncGroup
  6. CCTK_SyncGroupsByDirI
  7. CCTK_EnableGroupComm
  8. CCTK_DisableGroupComm
  9. CCTK_Barrier
  10. CCTK_OverloadParallelInit
  11. CCTK_OverloadExit
  12. CCTK_OverloadAbort
  13. CCTK_OverloadMyProc
  14. CCTK_OverloadnProcs

The overloadable function CCTK_SyncGroup is deprecated, a driver should instead provide a routine to overload the more general function CCTK_SyncGroupsByDirI.
