    On a CMP (Chip Multi-Processor) architecture, cache sharing impacts threads non-uniformly, where some threads may be slowed down significantly, while others are not. This may cause severe performance problems such as throughput decreasing, cache thrashing. This paper proposes an architectural support predicting method (ASPM) to predict inter-thread cache contention, and schedules threads based on ... View full abstract»
