# Information on the process

The next method discussed here is fairly simple: a MCMC simulation may take a long time to 
complete, particularly when running code, regardless of the chosen architecture. This method changes 
the number of iterations between two output displays. The prototype is simply:

````{only} cpp
```cpp
void setNbDump(int nbDump);
```
````

````{only} py
```python
setNbDump(nbDump)
```
````

The method takes a single integer argument that specifies the interval (modulo) at 
which the algorithm displays its progress. With the **default** value of 1000, 
the output will look like this:

```none
1000 events done
2000 events done
3000 events done
...
```
