Utility maximizing dynamic resource management in an oversubscribed energy-constrained heterogeneous computing system
Bhavesh Khemka,Ryan Friese,Sudeep Pasricha,Anthony A. Maciejewski,Howard Jay Siegel,Gregory A. Koenig,Sarah Powers,Marcia Hilton,Rajendra Rambharos,Steve Poole +9 more
TL;DR: Extensive sensitivity analyses of the heuristics in environments with different levels of heterogeneity show that heuristic with the ability to balance both energy consumption and utility exhibit the best performance because they save energy for use by future tasks.
Journal ArticleDOI
Utility Functions and Resource Management in an Oversubscribed Heterogeneous Computing Environment
Bhavesh Khemka,Ryan Friese,Luis Diego Briceno,Howard Jay Siegel,Anthony A. Maciejewski,Gregory A. Koenig,Chris Groër,Gene Okonski,Marcia Hilton,Rajendra Rambharos,Steve Poole +10 more
TL;DR: The results show the benefit of having fast heuristics that account for the importance of a task and the heterogeneity of the environment when making allocation decisions in an oversubscribed environment.
Journal ArticleDOI
Electrical Grid and Supercomputing Centers: An Investigative Analysis of Emerging Opportunities and Challenges
Natalie Bates,Girish Ghatikar,Ghaleb Abdulla,Gregory A. Koenig,Sridutt Bhalachandra,Mehdi Sheikhalishahi,Tapasya Patki,Barry Rountree,Stephen W. Poole +8 more
TL;DR: In this article, some of the largest supercomputing centers (SCs) in the United States are developing new relationships with their electricity service providers (ESPs), which are driven by a mutual interest to reduce energy costs and improve electrical grid reliability.
Proceedings ArticleDOI
An Analysis Framework for Investigating the Trade-Offs between System Performance and Energy Consumption in a Heterogeneous Computing Environment
Ryan Friese,Bhavesh Khemka,Anthony A. Maciejewski,Howard Jay Siegel,Gregory A. Koenig,Sarah Powers,Marcia Hilton,Jendra Rambharos,Gene Okonski,Stephen W. Poole +9 more
TL;DR: An analysis framework that will allow a system administrator to investigate the tradeoffs between system energy consumption and utility earned by a system (as a measure of system performance), and model these trade-offs as a bi-objective resource allocation problem.
Proceedings ArticleDOI
Energy and Power Aware Job Scheduling and Resource Management: Global Survey — Initial Analysis
Matthias Maiterth,Gregory A. Koenig,Kevin Pedretti,Siddhartha Jana,Natalie Bates,Andrea Borghesi,Dave Montoya,Andrea Bartolini,Milos Puzovic +8 more
TL;DR: This work describes the motivation and methodology of a first-of-its-kind global survey of HPC centers actively employing Energy and Power Aware Scheduling and Resource Management solutions for their production systems and presents the selection of participating sites.
