Detailed Description

template<unsigned int block_size>
class Opm::Accelerator::BdaSolver< block_size >

This class serves to simplify choosing between different backend solvers, such as cusparseSolver and openclSolver This class is abstract, no instantiations can of it can be made, only of its children
