Errors are displayed in unit:  6
Warnings are displayed in unit:  6
Matrix size:      10
Local matrix size:      10
Restart:       3
Left preconditioning
Iterative classical Gram-Schmidt
Default initial guess x_0 = 0
True residual computed at restart

Tolerance for convergence: 0.10E-09
Backward error on the unpreconditioned system Ax = b:
    the residual is normalised by ||b||
Backward error on the preconditioned system (P1)A(P2)y = (P1)b:
     the preconditioned residual is normalised by ||(P1)b||
