Workshop on High Performance Computing & Energy Efficiency in conjunction with VECPAR 2016

1st July, Porto, 2016


Current large scale IT systems are becoming pervasive. Data centers are used from web searches to protein analysis. Energy consumption of these systems is part of the fastest growing of the worldwide energy consumers. As an example, the top supercomputer in the Top500 ranking (Tianhe-2) consumes 18MW, enough to power a city of 30,000 citizens. Two observations can be made on HPC large scale systems: their energy consumption is too important and these systems are getting more and complex to manage. Moreover consuming such quantities of energy produces a lot of heat. Thermal-aware management aims to improve power consumption efficiency by coordinating resource management and thermal based decisions.

How to optimize the resources usage to obtain a "green" infrastructure and to improve energy efficiency?

This workshop is focused on scheduling policies and tools to address energy efficiency for large scale Data Centers and HPC applications.


The main topics to be covered by this workshop include (but are not limited to):

  • Energy-aware scheduling for Data Centers, Grid
  • Thermal-aware scheduling of Data Centers, Grid
  • Energy-aware metrics for Data Centers, Grid
  • Data Center optimization for energy and thermal efficiency
  • Energy- and Thermal models of Data Centers, Grid
  • Applications characterization for energy and thermal efficiency
  • Tools and simulators for resource management to improve energy and thermal efficiency
  • Energy- and Thermal-aware runtimes for Data Centers
  • Return of experiment on improving energy efficiency of Data Centers.
  • Green HPC in Green Cloud

Important dates

  • Submissions due: March 23th, 2016
  • Review decisions: April 15th, 2016
  • Camera-ready version of papers: May 15th, 2016


You should make your submissions through EasyChair.

Submitted papers must be formatted according to the rules of the Springer Series Lecture Notes in Computer Science (LNCS).

Please note that papers (for conference presentation) must not exceed 8 pages in length, when typeset using the LNCS format. Accepted papers will be distributed in electronic format to participants of VECPAR 2016 and HPCEE 2016.

The papers of the workshops will be published under the Springer LNCS series. The authors may be asked to revise the paper after the conference in order to meet the series requirements.


Registration will be done through VECPAR 2016 registration system.

He was Work Package leader of the European project CoolEmAll which aims at providing advanced simulation, visualization and decision support tools along with blueprints of computing building blocks for modular data center environment. His research currently focus on energy aware distributed systems. He serves on several PCs in the Energy aware systems, Cluster, Grid, Cloud and Peer to Peer fields. His research highlights are grid cluster & cloud computing, hybrid computing (CPU/GPU), large scale energy aware distributed systems, performance evaluation and ambient systems.
  • Patricia Stolf, Associate professor, IRIT lab, University of Toulouse, France - stolf@irit.fr Patricia Stolf is an associate professor since 2005. She teaches at the Toulouse University (France). She obtained a PhD in 2004 in the LAAS-CNRS laboratory (Toulouse-France) on Tasks scheduling on clusters for remote services with quality of service. She now works in the IRIT laboratory in the SEPIA team and is currently working in the field of distributed algorithms, energy efficiency and autonomic computing in large scale distributed systems like grid and clouds. She studies resources management, load-balancing, energy aware autonomic systems and energy and thermal-aware task scheduling. She has been involved in different research projects : in the ACTION COST IC0804 "Energy Efficiency in Large Scale Distributed Systems", in the European CoolEmAll project, in the national ANR SOP project and is currently involved in the national ANR Datazero project.
