computeRowIndexesWithMappingGpu()

template<typename T , bool ForceLegacy>

std::vector< HYPRE_Int > Opm::gpuistl::HypreInterface::computeRowIndexesWithMappingGpu	(	const GpuSparseMatrixWrapper< T, ForceLegacy > &	gpu_matrix,
		const std::vector< int > &	local_dune_to_local_hypre
	)

Compute row indexes for GPU matrix with ownership mapping.

GPU-specialized version that uses CSR row pointers to create row_indexes pointing directly into the FULL GPU matrix data for zero-copy operation. Same principle as CPU version but leverages GPU matrix's CSR structure.

Parameters

gpu_matrix	GPU matrix to analyze
local_dune_to_local_hypre	Mapping from Dune indices to Hypre indices (-1 for ghost)

Returns

Vector containing row indexes that map to full GPU matrix data positions
