struct _p_ISLocalToGlobalMapping{
PETSCHEADER(int)
int n; /* number of local indices */
int *indices; /* global index of each local index */
int globalstart; /* first global referenced in indices */
int globalend; /* last + 1 global referenced in indices */
int *globals; /* local index for each global index between start and end */
};
Note: mapping from Local to Global is scalable; but Global to Local may not be if the range of global values represented locally is very large.
Note: the ISLocalToGlobalMapping is actually a private object; it is included here for the MACRO ISLocalToGlobalMappingApply() to allow it to be inlined since it is used so often.
