The tools sizes are gathered in the file $MYCUTER/precision/config/tools.siz, which contains the following parameters.
| Parameter | Brief description |
| LIWK | the size of the integer workspace array used by the algorithms |
| LWK | the size of the single or double precision workspace array used |
| the algorithms, according to the precision of the instance installed | |
| LLOGIC | the size of the logical workspace array used by the algorithms |
| LCHARA | the number of ten character strings used as workspace by the algorithms |
| LFUVAL | the size of the array used to store the problem's function and derivative values. |
These parameters are assigned a value upon initial installation of CUTEr on the system. These values should be changed according to CUTEr messages issued at run-time, and CUTEr should be rebuilt.
Note that the main drivers, whose names match the regular expressions *ma.f and *ma.f90, declare parameters such as MMAX--the maximal number of constraint functions in the problem--which are not found in tools.siz. It may happen that CUTEr aborts the solving of a problem because one of these parameters has not been set, in the main driver source file, to an appropriate value. Since these parameters are package-dependent rather than architecture-, or size-dependent, they should be set to an appropriate value in the source file and the latter should be recast and recompiled.
