Projects

neOCampus Action de l'université Paul Sabatier
neOCampus will demonstrate the campus of the future: connected, innovative, smart and sustainable.

CoolEmAll (2011-2014) FP7 European project
CoolEmAll will provide means for a deep insight into the total energy consumption of data centres. To this end, the project will provide advanced planning and optimization tools for modular data centre environments. Once developed, these tools should help to minimize the energy consumption, and consequently the CO2 emissions of the IT infrastructure with related facilities.

SOP: think global Services for persOnal comPuter (2011-2014)
The objective of this ANR project is to build a hybrid working model for consumers and professional computing, that takes benefit from a mix between local installation/management and remote access to software and services located in distant dedicated datacenters or even in other non-used consumers’ machines

COST IC-1305: Network for Sustainable Ultrascale Computing (NESUS)
The goal of the NESUS Action is to establish an open European research network targeting sustainable solutions for ultrascale computing aiming at cross fertilization among HPC, large scale distributed systems, and big data management. The network will contribute to glue disparate researchers working across different areas and provide a meeting ground for researchers in these separate areas to exchange ideas, to identify synergies, and to pursue common activities in research topics such as sustainable software solutions (applications and system software stack), data management, energy efficiency, and resilience.

Finished projects

EcoToul (2012-2013)
This projects aims at providing information concerning mobility in Toulouse. Data from thousands of smartphones users from several means of transportation (foot, bicycle, cars, public transports,...) will be merged in a global information systems. This data will be used to compute a transportation status map of Toulouse. This map will be used to give time of transit of several means of transportation to users.

COST IC-0804: Energy efficiency in large scale distributed systems (2009-2013)
The main objective of the Action is to foster original research initiatives addressing energy awareness/saving and to increase the overall impact of European research in the field of energy efficiency in distributed systems.
The goal of the Action is to give coherence to the European research agenda in the field, by promoting coordination and encouraging discussions among the individual research groups, sharing of operational know-how (lessons-learned, problems found during practical energy measurements and estimates, ideas for real-world exploitation of energy aware techniques, etc.)

ANR-JST FP3C (Framework and Programming for Post Petascale Computing) : French-Japanese Project on Petaflop applications (2010-2013)
The goal of the project is to address the development of runtime systems for scientific applications running on petaflopic machines. Our contribution resides in the analysis of the energy consumption and leverages existing on such machines to handle their electricity hungriness.

PIREGRID: A Pyrenean Operational Grid (2009-2012)
PireGrid is an INTERREG IV A project which have two main objectives:
GreenNet (2008-2009) ARC Inria: Power aware software frameworks for high performance data transport and computing in large scale distributed systems
