This PR adds CUDA support to dense direct solver options (98, 99, 198, and 199) of BoomerAMG and MGR: - Options 98 and 99 compute the LU factorization with pivoting. - Options 198 and 199 compute the dense inverse matrix explicitly. Detailed list of changes below: * Add hypre_ParCSRMatrixToCSRMatrixAll_v2 * Add hypre_SeqVectorMigrate * Add hypre_ParVectorToVectorAll_v2 * Refactor implementation of BoomerAMG's Gaussian Elimination * Add hypre_GaussElimAllSetup and hypre_GaussElimAllSolve * Add device support via MAGMA and cuSOLVER to BoomerAMG's LU coarsest linear solver (options 98, 99) * Add device support via MAGMA and cuSOLVER to BoomerAMG's exact inverse solver (options 198, 199) * Add wrappers to MAGMA's getrf and getrs * Add MAGMA info on AMG stats + code formatting * Add wrappers to cuSOLVER and cuBLAS functions * Add wrapper hypre_magma_getri_nb * Add header file for collecting hypre functors * Add memory location to Gaussian elimination data structure * Improve description of coarsest level solver options * Update GE data structure in MGR * Change Ainv to Awork |
