Detailed Description

template<class X, class Y, class C, class P = Dune::PreconditionerWithUpdate<X, Y>>
class Opm::gpuistl::GpuBlockPreconditioner< X, Y, C, P >

Is an adaptation of Dune::BlockPreconditioner that works within the CuISTL framework.

Note

We aim to intgrate this into OwningBlockPreconditioner (or a relative thereof).

Constructor & Destructor Documentation

GpuBlockPreconditioner()

template<class X , class Y , class C , class P = Dune::PreconditionerWithUpdate<X, Y>>

Opm::gpuistl::GpuBlockPreconditioner< X, Y, C, P >::GpuBlockPreconditioner ( const std::shared_ptr< P > &  p, const std::shared_ptr< const communication_type > &  c  )

inline

Constructor.

constructor gets all parameters to operate the prec.

Parameters

p	The sequential preconditioner.
c	The communication object for syncing overlap and copy data points. (E.~g. OwnerOverlapCopyCommunication )
