int KSPSetMonitor(KSP ksp, int (*monitor)(KSP,int,double,void*), void *mctx)Collective on KSP
ksp | - iterative context obtained from KSPCreate() |
monitor | - pointer to function (if this is PETSC_NULL, it turns off monitoring |
mctx | - [optional] context for private data for the monitor routine (use PETSC_NULL if no context is desired) |
monitor (KSP ksp, int it, double rnorm, void *mctx)
ksp | - iterative context obtained from KSPCreate() |
it | - iteration number |
rnorm | - (estimated) 2-norm of (preconditioned) residual |
mctx | - optional monitoring context, as set by KSPSetMonitor() |
-ksp_monitor | - sets KSPDefaultMonitor() |
-ksp_truemonitor | - sets KSPTrueMonitor() |
-ksp_xmonitor | - sets line graph monitor, uses KSPLGMonitorCreate() |
-ksp_xtruemonitor | - sets line graph monitor, uses KSPLGMonitorCreate() |
-ksp_singmonitor | - sets KSPSingularValueMonitor() |
-ksp_bsmonitor | - sets BlockSolve95 monitor that prints both scaled and unscaled residual norms |
-ksp_cancelmonitors | - cancels all monitors that have been hardwired into a code by calls to KSPSetMonitor(), but does not cancel those set via the options database. |
Several different monitoring routines may be set by callingKSPSetMonitor() multiple times; all will be called in theorder in which they were set.
