Detailed Description

template<typename RADIAL_BASIS_FUNCTION_T>
class precice::mapping::BatchedRBFSolver< RADIAL_BASIS_FUNCTION_T >

This class solves the PU-RBF interpolation in a batched manner, i.e., clusters are computed in parallel. The parallelization can be handled through GPUs or OpenMP. It uses Kokkos-kernels dispatch the kernels on the selected execution backend. Only the mesh indexing is handled on the CPU through boost geometry, all other components are handled in parallel. The solver is compatible with the MPI-parallel layout of the PURBF class itself, which means in this case that the problem is solved purely local, but each rank can instantiate and launch its own solver.

◆ BatchedRBFSolver()

template<typename RADIAL_BASIS_FUNCTION_T>

precice::mapping::BatchedRBFSolver< RADIAL_BASIS_FUNCTION_T >::BatchedRBFSolver	(	RBF_T	basisFunction,
		mesh::PtrMesh	inMesh,
		mesh::PtrMesh	outMesh,
		const std::vector< mesh::Vertex > &	centers,
		double	clusterRadius,
		Polynomial	polynomial,
		bool	computeEvaluationOffline,
		MappingConfiguration::GinkgoParameter	ginkgoParameter )

Essentially an initialize of the solver: allocates device memory and computes the LU decompositions etc
