Online Risk Analytics on the Cloud
Cluster Computing and the Grid, IEEE International Symposium on
By Hyunjoo Kim, Shivangi Chaudhari, Manish Parashar, Christopher Marty
Issue Date:May 2009
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
2013 IEEE World Congress on Services (SERVICES)
By Gueyoung Jung,Tridib Mukherjee,Shruti Kunde,Hyunjoo Kim,Naveen Sharma,Frank Goetz
Issue Date:June 2013
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
2013 IEEE International Conference on Web Services (ICWS)
By Gueyoung Jung,Hyunjoo Kim
Issue Date:June 2013
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
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
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...
Accelerating MapReduce Analytics Using CometCloud
2012 IEEE 5th International Conference on Cloud Computing (CLOUD)
By Moustafa AbdelBaky,Hyunjoo Kim,Ivan Rodero,Manish Parashar
Issue Date:June 2012
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
Cloud Computing Technology and Science, IEEE International Conference on
By Yaakoub El-Khamra, Hyunjoo Kim, Shantenu Jha, Manish Parashar
Issue Date:December 2010
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...
An Autonomic Approach to Integrated HPC Grid and Cloud Usage
e-Science and Grid Computing, International Conference on
By Hyunjoo Kim, Yaakoub el-Khamra, Shantenu Jha, Manish Parashar
Issue Date:December 2009
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
Multimedia and Expo, IEEE International Conference on
By Hyunjoo Kim, Sooyong Kang, H.Y. Yeom
Issue Date:July 2003
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...
The Cost of Checkpointing,Logging and Recovery for the Mobile Agent Systems
Pacific Rim International Symposium on Dependable Computing, IEEE
By Hyunjoo Kim, Heon Y. Yeom, Taesoon Park, Hyoungwoo Park
Issue Date:December 2002
The reliable execution of a mobile agent is a very important design issue to build a mobile agent system and many fault-tolerant schemes have been proposed. Hence, in this paper, we present the experimental evaluation of the performance of the fault-tolera...
The Performance of Checkpointing and Replication Schemes for Fault Tolerant Mobile Agent Systems
Reliable Distributed Systems, IEEE Symposium on
By Taesoon Park, Ilsoo Byun, Hyunjoo Kim, Heon Y. Yeom
Issue Date:October 2002
This paper evaluates the performance of checkpointing and replication schemes for the fault tolerant mobile agent system. For the quantitative comparison, we have implemented an experimental system on top of the Mole mobile agent system and also built a si...
Exploring application and infrastructure adaptation on hybrid grid-cloud infrastructure
Found in: Proceedings of the 19th ACM International Symposium on High Performance Distributed Computing (HPDC '10)
By Hyunjoo Kim, Manish Parashar, Shantenu Jha, Yaakoub el-Khamra
Issue Date:June 2010
Clouds are emerging as an important class of distributed computational resources and are quickly becoming an integral part of production computational infrastructures. An important but oft-neglected question is, what new applications and application capabi...
