To support this the solveSystem methods of the LinearSolverInterface gets an optional additional template parameter of type boost::any. It can hold any copy constructable object. In our case it is used to pass the information about the parallelization into the solvers of dune-istl without the compiler needing to know their type. Inside of LinearSolverIstl::solveSystem we check whether the type stored inside of boost::any is the new ParallelIstlInformation. If this is the case we extract the information and use the parallel solvers if available, otherwise we solve serial/sequential. The new ParallelIstlInformation is needed as the OwnerOverlapCopyCommunication is not copy constructable. This is indeed a design flaw that should and will fixed upstream, but for the time being we need ParallelIstlInformation to transfer the ParallelIndexSet and RemoteIndices objects.
