The utilization bounds of partitioned and pfair static-priority scheduling on multiprocessors are 50%
Bjorn A. Andersson, J. A. Jonsson · 2004
This paper studies preemptive static-priority scheduling on multiprocessors. We consider two approaches: global pfair static-priority scheduling and partitioned traditional static priority scheduling. We prove that if presented algorithms are used and if less than 50% of the capacity is used then all deadlines are met. It is known that no static-priority multiprocessor scheduling algorithm can achieve a utilization bound greater than 50%.
