Concurrent applications in virtualized environments (VE) encounter synchronization problems such as Lock Holder Preemption (LHP). Hybrid co-scheduling is an effective approach to address such problems. However, the contention and exclusiveness between multiple concurrent domains in hybrid co-scheduling cause a serious performance degradation and unfairness. To keep the benefits brought by hybrid co-scheduling for multiple concurrent domains in VE, we propose two optimization schemes named… CONTINUE READING
