Gather all nonlocal indices for this IS and present them as another sequential index set.
PetscErrorCode ISGetNonlocalIS(IS is, IS *complement)
Collective on IS
is -the index set
complement -sequential IS with indices identical to the result of
complement represents the result of ISGetNonlocalIndices as an IS.
Therefore scalability issues similar to ISGetNonlocalIndices apply.
The resulting IS must be restored using ISRestoreNonlocalIS().
