The Eucalyptus Open-Source Cloud-Computing System
Daniel Nurmi,Rich Wolski,Chris Grzegorczyk,Graziano Obertelli,Sunil Soman,Lamia Youseff,Dmitrii Zagorodnov +6 more
TL;DR: This work presents Eucalyptus -- an open-source software framework for cloud computing that implements what is commonly referred to as Infrastructure as a Service (IaaS); systems that give users the ability to run and control entire virtual machine instances deployed across a variety physical resources.
Journal ArticleDOI
Adaptive computing on the Grid using AppLeS
Francine Berman,Rich Wolski,Henri Casanova,Walfredo Cirne,Holly Dail,M. Faerman,Silvia Figueira,Jim Hayes,Graziano Obertelli,Jennifer M. Schopf,Gary Shao,Shava Smallen,Neil Spring,Alan Su,D. Zagorodnov +14 more
TL;DR: The AppLeS (Application Level Scheduling) project provides a methodology, application software, and software environments for adaptively scheduling and deploying applications in heterogeneous, multiuser grid environments and outlines the findings.
Proceedings ArticleDOI
The AppLeS Parameter Sweep Template: User-Level Middleware for the Grid
TL;DR: This paper describes a user-level Grid middleware project, the AppLeS Parameter Sweep Template (APST), that uses application-level scheduling techniques and various Grid technologies to allow the efficient deployment of parameter sweep applications over the Grid.
Proceedings ArticleDOI
VGrADS: enabling e-Science workflows on grids and clouds with fault tolerance
Lavanya Ramakrishnan,Charles Koelbel,Yang-Suk Kee,Rich Wolski,Daniel Nurmi,Dennis Gannon,Graziano Obertelli,Asim YarKhan,Anirban Mandal,T. Mark Huang,Kiran Thyagaraja,Dmitrii Zagorodnov +11 more
TL;DR: This paper applies VGrADS' virtual grid execution system (vgES) for scheduling a set of deadline sensitive weather forecasting workflows and reports on experiences with virtualized reservations for batchqueue systems, coordinated usage of TeraGrid, Amazon EC2, and Eucalyptus resources, and fault tolerance through automated task replication.
Proceedings ArticleDOI
Application-aware scheduling of a magnetohydrodynamics application in the Legion metasystem
TL;DR: A new high-performance scheduler is described that incorporates dynamic system information, application requirements, and a detailed performance model in order to create performance efficient schedules.
