The following control parameters are related to the FFOptimizer. The default value for each parameter is given in parentheses.
- ffostp – the delta used for calculating first and second derivatives by finite differences (0.01).
- ffdedi – If running in parallel and ffdedi is set to 1 then the master process will run as a dedicated dispatcher and will not perform any computations. The default value depends on the number of processors used in the calculation (1 for Nproc > 3).
