Research Activities

My main activities focus on the used of virtualization mechanisms (VM) in the context of Grids. This work is done in the framework of the  XtreemOS European Project.

I have studied the complementarity of virtualization technologies and SSI OS. An article was presented at VHPC'08 (see: "Complementarity between Virtualization and Single System Image Technologies"). 

 In addition, I have worked on an extension of the Goldberg Theory.  This extension aims at formally classifying the different existing virtualization systems (see: "Refinement Proposal of the Goldberg's Theory").

Moreover, in summer 2008, I have co-supervised an intern. This intern has worked on a system able to deploy the SSI Kerrighed on Grid'5000 (Kargo) and another system (VMdeploy) which aims to deploy and manage Virtual Machines on the Grid. Now I work on a new version of VMdeploy entitled Saline. Saline is able to manage cluster job VMs at grid level by moving the whole set of VMs from one site to another in a transparent way for the running job (see: "Saline: Improving Best-Effort Job Management in Grids"). In addition, I work on algorithms to efficiently save the VM snapshots from n compute nodes to one master node (see: "Kget+: An efficient tool for managing VM image snapshots").

I am also interested in the cloud computing area and the federation of virtual infrastructures (see: "Clouds: A New Playground for the XtreemOS Grid Operating System").
