Jongman Kim Wins Best Paper Award

Atlanta, GA

Jongman Kim and his colleagues won the Best Paper Award at the 13th IEEE International Conference on High Performance Computing and Communications, held September 2-4 in Banff, Canada.

The paper entitled "A High-Performance and Energy-Efficient Virtually Tagged Stack Cache Architecture for Multi-Core Environments" was selected for this award out of 271 papers submitted to the conference. Dr. Kim, who is an assistant professor in the School of Electrical and Computer Engineering (ECE) at Georgia Tech, coauthored this paper with members of his research group, ECE Ph.D. student Suk Chan Kang and ECE postdoctoral fellow Hyunggyu Lee, and Chrysostomos Nicopoulos from the Department of ECE at the University of Cyprus.

Dr. Kim and his team have developed the first stack cache architecture geared toward multicore processors. Their research is the hardware support for an operating system providing utility that selects and boosts up one performance-dominating target multi-threaded process. He and his team demonstrated that special level-one virtually tagged stack caches can significantly boost the performance of a system running one heavy, dominating, multi-threaded workload–among other applications–while actually reducing its energy consumption. This scheme is aimed at modern server environments and data centers, and results from this research are fostering new directions in several areas of multicore computing, which is expected to be the main design paradigm for future digital convergence platforms.
