Grids and Clouds

Did you say "grid & cloud" ?


Computing Grids are a form of distributed computing whereby a “super virtual computer” is composed of many networked loosely coupled computers acting together to perform very large tasks. Since 2000, the emergence of grids has revolutionized many services already offered by the internet because it offers rapid computation, large scale data storage and flexible collaboration by harnessing together the power of a large number of commodity computers or clusters of other basic machines. The grid was devised for use in scientific fields, such as particle physics and bioinformatics, where large volumes of data, or very rapid processing, or both, are necessary..

Cloud computing is a computing term or metaphor that evolved in the late 2000s, based on utility and consumption of computer resources. Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Main cloud charactersitics include resources pooling and elasticity. According to the National Institute of Standards and Technology (NIST), Cloud computing means accessing shared and configurable computing resources, on-demand, through a broad network access.

France Grilles

France Grilles is a national (French) scientific interest group that gathers 8 partners (MESR, CNRS, INSERM, CEA, INRA, INRIA, RENATER, CPU). Infrastructures are distributed on many different production sites across the country. France Grilles represents France within the EGI european e-infrastructure, playing the role of the French NGI (National Grid Initiative).


Missions, works and activities


I was involved in operations and development of operational tools for the european grid infrastructure between 2004 and 2014:

  • at IN2P3/CNRS Computing Centre (Villeurbanne, France) from 2004 to 2008 then from 2011 to 2014, and at STFC/Rutherford Appleton Laboratory (Didcot, UK) from 2008 to 2010
  • Within the context of 4 FP7 european projects: EGEE-I (2004-2006), EGEE-II (2006-2008), EGEE-III (2008-2010) and EGI-InSPIRE (2010-2014)
  • Within then national infrastructure France Grilles from 2011 to 2014.
