A group of four ECE students in Assistant Professor Onur Mutlu's SAFARI
research group won Best Paper honors for "Row Buffer Locality Aware Caching Policies for Hybrid Memories"
in the Computer Systems and Applications track at the 30th International Conference on Computer Design
. Lead author and third-year Ph.D. student HanBin Yoon (top left) presented the paper at the conference earlier this month, and his co-authors included ECE Ph.D. students Justin Meza (bottom left) and Rachata Ausavarungnirun (top right), and recent ECE undergraduate alumna Rachael Harding (bottom right).
The paper proposes new techniques to intelligently manage data allocation in a scalable hybrid memory system comprising multiple memory technologies with different strengths and weaknesses (e.g., DRAM and phase change memory). The paper recommends that data management be performed with an awareness of row buffers, which are present in all technologies and provide similar latency and bandwidth regardless of the technology. The authors show that doing so provides significantly higher system performance, energy efficiency and fairness than the best previous techniques. The paper can be found here
