Launching lots of separate parfor loops can be inefficient if each loop duration is small. Unfortunately, as you are probably aware, you cannot break out of a parfor loop. One alternative might be to use parfeval. The idea would be to make many parfeval calls (but not too many), and then you can terminate when you have sufficient results.
