Virtual Snooping: Filtering Snoops in Virtualized Multi-cores
Found in: Microarchitecture, IEEE/ACM International Symposium on
By Daehoon Kim, Hwanju Kim, Jaehyuk Huh
Issue Date:December 2010
pp. 459-470
Virtualization has been rapidly expanding its applications in numerous server and desktop environments to improve the utilization and manageability of physical systems. Such proliferation of virtualized systems opens a new opportunity to improve the scalab...
 
Subspace Snooping: Exploiting Temporal Sharing Stability for Snoop Reduction
Found in: IEEE Transactions on Computers
By Jeongseob Ahn,Daehoon Kim,Jaehong Kim,Jaehyuk Huh
Issue Date:November 2012
pp. 1624-1637
Although snoop-based coherence protocols provide fast cache-to-cache transfers with a simple and robust coherence mechanism, scaling the protocols has been difficult due to the overheads of broadcast snooping. In this paper, we propose a coherence filterin...
 
Location-Based Large-Scale Landmark Image Recognition Scheme for Mobile Devices
Found in: 2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing (MUSIC)
By Daehoon Kim,Eenjun Hwang,Seungmin Rho
Issue Date:June 2012
pp. 47-52
In this paper, we propose a location-based large-scale landmark image recognition scheme for mobile devices such as smart phones. To achieve this goal, we collected landmark images all around the world, which were available on the web. For each landmark, w...
 
A Voronoi-Based Hybrid Navigation System for Road Network Database
Found in: Advanced Language Processing and Web Information Technology, International Conference on
By Daehoon Kim, Eenjun Hwang
Issue Date:July 2008
pp. 398-403
The navigation system has become one of the essential IT gadgets, especially to the drivers. In addition to the basic functionality of finding a shortest path between two nodes, recent navigation systems are required to provide extra intelligent services t...
 
vCache: Providing a Transparent View of the LLC in Virtualized Environments
Found in: IEEE Computer Architecture Letters
By Daehoon Kim,Hwanju Kim,Jaehyuk Huh
Issue Date:July 2013
pp. 1
Since most of the current multi-core processors use a large last-level cache (LLC), efficient use of an LLC is critical for the overall performance of multi-cores. To improve the caching efficiency, page coloring is a representative software-based approach...
 
Subspace snooping: filtering snoops with operating system support
Found in: Proceedings of the 19th international conference on Parallel architectures and compilation techniques (PACT '10)
By Daehoon Kim, Jaehong Kim, Jaehyuk Huh, Jeongseob Ahn
Issue Date:September 2010
pp. 111-122
Although snoop-based coherence protocols provide fast cache-to-cache transfers with a simple and robust coherence mechanism, scaling the protocols has been difficult due to the overheads of broadcast snooping. In this paper, we propose a coherence filterin...
     
Facilitating developer-user interactions with mobile app review digests
Found in: CHI '13 Extended Abstracts on Human Factors in Computing Systems (CHI EA '13)
By Daehoon Kim, Jae-Gil Lee, Jeungmin Oh, Junehwa Song, Uichin Lee
Issue Date:April 2013
pp. 1809-1814
As users are interacting with a large of mobile apps under various usage contexts, user involvements in an app design process has become a critical issue. Despite this fact, existing apps or app store platforms only provide a limited form of user involveme...
