Abstract: We devise the first constant-approximate feasibility test for sporadic multiprocessor real-time scheduling. We give an algorithm that, given a task system and e > 0, correctly decides either that the task system can be scheduled using the earliest deadline first algorithm on m speed-(2-1/m+e) machines, or that the system is infeasible for m speed-1 machines. The running time of the algorithm is polynomial in the size of the task system and 1/e. We also provide an improved bound trading off speed for additional machines.
