In todays turbulent market conditions, the ability to generate accurate and timely risk measures has become critical to operating successfully, and necessary for survival. Value-at-Risk (VaR) is a market standard risk measure used by senior management and ...
CloudAdvisor: A Recommendation-as-a-Service Platform for Cloud Configuration and Pricing
Found in: 2013 IEEE World Congress on Services (SERVICES)
By Gueyoung Jung,Tridib Mukherjee,Shruti Kunde,Hyunjoo Kim,Naveen Sharma,Frank Goetz
Issue Date:June 2013
pp. 456-463
The proliferation of cloud computing can imply a barrier to cloud users. When deploying their complex workloads into clouds, cloud users are typically overwhelmed by too many technical choices. Moreover, underlying technologies and pricing mechanisms of cl...
Optimal Time-Cost Tradeoff of Parallel Service Workflow in Federated Heterogeneous Clouds
Found in: 2013 IEEE International Conference on Web Services (ICWS)
By Gueyoung Jung,Hyunjoo Kim
Issue Date:June 2013
pp. 499-506
Federated cloud enables a workflow to be deployed in multiple private and public clouds. By facilitating external cloud-based services to execute sub-tasks of the workflow, service workflow owners can reduce the cost of executing the workflow, while meetin...
Enabling High-Performance Computing as a Service
Found in: Computer
By Moustafa AbdelBaky,Manish Parashar,Hyunjoo Kim,Kirk E. Jordan,Vipin Sachdeva,James Sexton,Hani Jamjoom,Zon-Yin Shae,Gergina Pencheva,Reza Tavakoli,Mary F. Wheeler
Issue Date:October 2012
pp. 72-80
With the right software infrastructure, clouds can provide scientists with "as a service" access to high-performance computing resources. An award-winning prototype framework transforms the Blue Gene/P system into an elastic cloud to run a repres...

MapReduce-Hadoop has emerged as an effectiveframework for large-scale data analytics, providing support forexecuting jobs and storing data in a parallel and distributedmanner. MapReduce has been shown to perform very well onlarge datacenters running applic...
Exploring the Performance Fluctuations of HPC Workloads on Clouds
Found in: Cloud Computing Technology and Science, IEEE International Conference on
By Yaakoub El-Khamra, Hyunjoo Kim, Shantenu Jha, Manish Parashar
Issue Date:December 2010
pp. 383-387
Clouds enable novel execution modes often supported by advanced capabilities such as autonomic schedulers. These capabilities are predicated upon an accurate estimation and calculation of runtimes on a given infrastructure. Using a well understood high-per...

By Hyunjoo Kim, Yaakoub el-Khamra, Shantenu Jha, Manish Parashar
Issue Date:December 2009
pp. 366-373
Clouds are rapidly joining high-performance Grids as viable computational platforms for scientific exploration and discovery, and it is clear that production computational infrastructures will integrate both these paradigms in the near future. As a result,...
Node selection for a fault-tolerant streaming service on a peer-to-peer network
Found in: Multimedia and Expo, IEEE International Conference on
By Hyunjoo Kim, Sooyong Kang, H.Y. Yeom
Issue Date:July 2003
pp. 117-120
Peer-to-peer (P2P) networks are attracting considerable research interest because of their scalability and high performance relative to cost. One of the important services on a P2P network is the streaming service. However, because each node in the P2P net...
