Earliest-Deadline-First is considered to be the optimal scheduling algorithm on CPUs that
support preemptive scheduling. Why is this the case?
Its because the algorithm supports any number of CPUs.
It's because the closest deadline is the one that you are most likely to miss, and s0 it should be
prioritized.
Its not, this is a trick question.
Its because of the preemptive nature of the algorithm, not the EDF ordering
