Many octave computations run much faster on multicore machines. In addition, embarrassing parallelism can be easily exploited using octave packages such as parallel. | ||

This requires some changes to the standard desktop user interaction model, relying more on the faster local client response. Jupyter notebook is an example of such an interface. | |||
