| Outline of Final Research Achievements |
To improve the energy efficiency of big data processing, this work focused on optimizing memory systems, the major performance/power bottlenecks during executing big data applications, by hardware/software-side approaches. In particular, this work is based on two novel approaches: (1) address translation aware cache management and (2) storage class memory aware power management. Consequently, it is quantified that a few tens of percent of energy efficiency improvement can be achieved by applying those methods.
