You can use R³S Worker or a third-party grid computing system to perform the execution.

Users can operate R³S Process Manager without knowing how to use R³S Modeler.

While developing a model with R³S Modeler, you can specify run-time parameters to provide ways to control what the model does. These run-time parameters can include things such as the portfolio date, the projection step lengths, and the location of external assumptions and data. In R³S Process Manager, you can specify values for these runtime parameters while preparing models for execution.
