-ksp_ksp_type <solver> | - the type of the inner solver (GMRES or any of its variants for instance) | |

-ksp_pc_type <preconditioner> | - the type of the preconditioner applied to the inner solver | |

-ksp_ksp_max_it <maxits> | - the maximum number of inner iterations (iterations of the inner solver) | |

-ksp_ksp_rtol <tol> | - sets the relative convergence tolerance of the inner solver | |

-ksp_tsirm_cgls <number> | - if 1 use CGLS solver in the minimization step, otherwise use LSQR solver | |

-ksp_tsirm_max_it_ls <maxits> | - the maximum number of iterations for the least-squares minimization solver | |

-ksp_tsirm_tol_ls <tol> | - sets the convergence tolerance of the least-squares minimization solver | |

-ksp_tsirm_size_ls <size> | - the number of residuals for the least-squares minimization step |
