[petsc-users] -pc_mg_monitor

[David Scott]

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
