Hi, No I didn't put "no-debugging" when I compiled. I will re-compile it. I am solving a set of Maxwell equations in integral form. I know that my coefficient matrix has a large condition number too. Would you please explain more about "-ksp_view" and "-log_summary"? How can I use these options? I think the problem is deeper than some sort of compilation flags. Can I get number of iterations and know whether the solution has converged or not? In my case, the slow convergence can be due to badly conditioned matrices. I expected to use default preconditioner which should ILU I guess.
