By integrating multiple cores in a single chip, Chip Multi-Processors (CMP) provides an attractive approach to improve both system throughput and efficiency. This integration allows the sharing of on-chip resources which may lead to destructive interference between the executing workloads. Memory-subsystem is an important shared resource that contributes significantly to the overall throughput and power consumption. In order to prevent destructive interference, the cache capacity and memory bandwidth requirements of the last level cache have to be controlled. While previously proposed schemes focus on resource sharing within a chip, the authors explore additional possibilities both inside and outside a single chip.
