13 Interface changes

The section shows interface-specific changes to the MOSEK Command Line Tools in version 10.2 compared to version 9. See the release notes for general changes and new features of the MOSEK Optimization Suite.

13.1 Important changes compared to version 9

  • Parameters. Users who set parameters to tune the performance and numerical properties of the solver (termination criteria, tolerances, solving primal or dual, presolve etc.) are recommended to reevaluate such tuning. It may be that other, or default, parameter settings will be more beneficial in the current version. The hints in Sec. 6 (Debugging Tutorials) may be useful for some cases.

  • Multithreading. In the interior-point optimizer it is posible to set the number of threads with MSK_IPAR_NUM_THREADS before each optimization, and not just once per process. The parameter MSK_IPAR_INTPNT_MULTI_THREAD is no longer relevant and was removed.
