Detailed Description

template<unsigned int block_size>
class Opm::Accelerator::BILU0< block_size >

This class implements a Blocked ILU0 preconditioner The decomposition is done on GPU, using exact decomposition, or ChowPatel decomposition The preconditioner is applied via two exact triangular solves
