# TaoDefaultSMonitor
Default routine for monitoring progress of `TaoSolve()` 
## Synopsis
```
#include "petsctao.h" 
PetscErrorCode TaoDefaultSMonitor(Tao tao, void *ctx)
```
Collective


## Input Parameters

- ***tao -*** the `Tao` context
- ***ctx -*** `PetscViewer` context of type `PETSCVIEWERASCII`



## Options Database Key

- ***-tao_smonitor -*** turn on default short monitoring





## Note
Same as `TaoMonitorDefault()` except
it prints fewer digits of the residual as the residual gets smaller.
This is because the later digits are meaningless and are often
different on different machines; by using this routine different
machines will usually generate the same output.
