The matrix is scaled in my problem. Before solving this, I do a LeftScaling and observe that it gives better convergence. However, considering that MKL solver can solve my problem with tolerance 1e-12. I'm confused that iterative solver cannot give the result with the required tolerance.
----------------------------------------------------------------------------------------------------------------------------
Is the MKL solver a direct solver?
