Collective
Input Parameter#
is - the index set
Output Parameter#
complement - sequential
ISwith indices identical to the result ofISGetNonlocalIndices()

Complement represents the result of ISGetNonlocalIndices() as an IS.
Therefore scalability issues similar to ISGetNonlocalIndices() apply.
The resulting IS must be restored using ISRestoreNonlocalIS().
