Memory usage

Explains how OPL uses and allocates memory, and suggests actions to improve memory usage, mostly for data structures, object termination, engine parameters, and oplrun.

If your system runs out of memory
Indicates the various parts of IBM ILOG OPL that use memory.
Building data structures differently
Explains how to tune the way data structures inside a model are built.
Terminating data objects
Explains how to use the method end to free memory in IBM ILOG Script and interfaces.
Changing engine parameters
Explains how to change engine parameters to modify the way the engine solves a model.
Using oplrun
Explains how to reduce overhead by using oplrun in command line mode.
Scaling down the size of the model
For the model to be solved more easily.
