Detailed Description

template<class C, class P>
class Dune::NonoverlappingBlockPreconditioner< C, P >

Nonoverlapping parallel preconditioner.

This is essentially a wrapper that take a sequential preconditoner. In each step the sequential preconditioner is applied and then all owner data points are updated on all other processes.
