Description

Specifies an upper limit on the amount of central memory, in megabytes, that CPLEX is permitted to use for working memory before compressing memory, swapping to disk files, or taking other actions.

These actions are defined by the parameter node storage file switch, which controls how CPLEX behaves when specifying this limit.

Values

Any nonnegative number, in megabytes; default: 2048
