itaps-parallel Confusion between BOUNDARY, INTERNAL, GHOST

I think BOUNDARY is inter-part boundary (no process involved) and both
iMeshP_getEntStatus() and iMeshP_getEntStatusArr() takes input as
"iMeshP_PartHandle part_handle", see below:

void iMeshP_getEntStatus(iMesh_Instance instance,
                    /*in*/ const iMeshP_PartHandle part_handle,
                    /*in*/ const iBase_EntityHandle entity_handle,
                   /*out*/ int* par_status, //
                   int *err);
