[petsc-users] How to disable KSP message

[Jin, Shuangshuang]

Hi, does anyone know what is the command line option to disable the following printout message about KSP convergence?

0: PETSc KSP converged after 1 iterations, reason: 3
0: PETSc KSP converged after 0 iterations, reason: 3
0: PETSc KSP converged after 1 iterations, reason: 3
0: PETSc KSP converged after 0 iterations, reason: 3
0: PETSc KSP converged after 1 iterations, reason: 3

Thanks,
Shuangshuang
