文摘

Throughput and fairness are largely conflicting optimization goals on AMPs. Previous asymmetry-aware schedulers fail to effectively deal with user priorities. ACFS achieves an average 23% fairness improvement over state-of-the-art schemes. Predicting cross-core performance on current AMPs is one of the major challenges.
