Default

Wall clock time

This option decides how computation times are measured for both reporting performance and terminating optimization when a time limit has been set. Small variations in measured time on identical runs may be expected on any computer system with any setting of this parameter. Possible values are:

  • Automatic

  • CPU time

  • Wall clock time

The setting ‘Automatic’ allows CPLEX to choose wall clock time when other parameters invoke parallel optimization and to choose CPU time when other parameters enforce sequential (not parallel) optimization.
