Operating System Transparent DRAM Power Management for Disaggregated Memory
Undergraduate Researcher
- Advised by Prof. Jae W. Lee, Architecture and Code Optimization Lab @ SNU
- Conducted experiment scheduling virtual machines running Cloudsuite 4.0 on an actual machine configuration that can sufficiently represent the major features of the suggested non-configurable system
- Proposed estimation methodology for performance and DRAM power metrics of suggested system, where metrics are obtained using PCM(Performance Counter Monitor)
- Fine-tuned Cloudsuite 4.0 workloads to work correctly on trace generation using binary instrumentation, INTEL PIN
