    We have an SMP system with two processors, 0 and 1. There are three programs P1,P2,P3 to be executed. All of them are CPU-bound (i.e. no I/O and only minimal non-interfering memory interaction). They have runtimes of 5, 15, and 20 sec respectively. Explore possible scheduling scenarios by stating the possible and different elapsed times for each one of them. (Nothing is impossible, the implausible is possible.) We just need the different elapsed time for the group of three programs.
