Re: [petsc-users] -pc_mg_monitor

[David Scott]

Thanks for the replies. It seems that the reference to -pc_mg_monitor in
http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/PC/PCMG.html
should be removed.

    Hello,

    I am using MINRES with GAMG and have supplied various options

    #PETSc Option Table entries:
    -ksp_max_it 500
    -ksp_monitor_true_residual
    -log_summary
    -mg_levels_ksp_max_it 2
    -mg_levels_ksp_type chebyshev
    -mg_levels_pc_type sor
    -options_left
    -pc_gamg_agg_nsmooths 1
    -pc_gamg_threshold 0.03
    -pc_gamg_type agg
    -pc_gamg_verbose 7
    -pc_mg_monitor
    #End of PETSc Option Table entries
    There is one unused database option. It is:
    Option left: name:-pc_mg_monitor (no value)

    Does this mean that I should have supplied an integer value with
    -pc_mg_monitor or is it not applicable in this case? If I should
    have supplied a value what is the allowed range?

    Thanks in advance,

    David
