I am trying to solve a large system of log-linearized equations (essentially the log-linearized FOCs of a large multi-sector RBC model, model and data are here). The model works fine on smaller samples, however with 1662 equations and~1.800.000 pre-defined paramaters the preprocessor runs into trouble:

```
Using 64-bit preprocessor
"/usr/lib/dynare/matlab/preprocessor64/dynare_m" KW_replic_reduced.mod minimal_workspace: Killed
Starting Dynare (version 4.5.4).
Starting preprocessing of the model file ...
Found 1662 equation(s).
Evaluating expressions...done
Computing static model derivatives:
- order 1
Error using dynare (line 225)
DYNARE: preprocessing failed
```

I am wondering:

- Is this simply a problem of computational capacity or could it also be due to the parameterization?
- It seems to me that the RAM is the limiting factor. Would rerunning it on a stronger computer solve the problem (I am running it on 16GB RAM and Linux)?
- Is there anything else I can do about it except reducing the size of the model?
