Realizing Fast, Scalable and Reliable Scientific Computations in Grid Environments
Yong Zhao, Ioan Raicu, Ian Foster +3
The practical realization of managing and executing large scale scientific computations efficiently and reliably is quite challenging. Scientific computations often involve thousan…
Enabling Loosely-Coupled Serial Job Execution on the IBM BlueGene/P Supercomputer and the SiCortex SC5832
Ioan Raicu, Zhao Zhang, Mike Wilde +1
Our work addresses the enabling of the execution of highly parallel computations composed of loosely coupled serial jobs with no modifications to the respective applications, on la…
Data Diffusion: Dynamic Resource Provision and Data-Aware Scheduling for Data Intensive Applications
Ioan Raicu, Yong Zhao, Ian Foster +1
Data intensive applications often involve the analysis of large datasets that require large amounts of compute and storage resources. While dedicated compute and/or storage farms o…
Distributed Averaging in the presence of a Sparse Cut
Hariharan Narayanan
We consider the question of averaging on a graph that has one sparse cut separating two subgraphs that are internally well connected. While there has been a large body of work devo…
In Search of Simplicity: A Self-Organizing Multi-Source Multicast Overlay
Matei Ripeanu, Adriana Iamnitchi, Ian Foster +1
Multicast communication primitives have broad utility as building blocks for distributed applications. The challenge is to create and maintain the distributed structures that suppo…
Performance Analysis of the Globus Toolkit Monitoring and Discovery Service, MDS2
Xuehai Zhang, Jennifer M. Schopf
Monitoring and information services form a key component of a distributed system, or Grid. A quantitative study of such services can aid in understanding the performance limitation…
