    2. Main scheduling algorithms

    Simply adding an extra processor to the platform drastically increases the complexity of real-time scheduling problems. As early as 1969, C.L. Liu observed that very few results known in single-processor environments could be directly generalized to multiprocessor systems. . The first optimal algorithm, i.e. to schedule task systems with total utilization equal to platform capacity, was not proposed until 1993.
