Focus on a joint research project: CLOUDSHARE

CLOUDSHARE (2009-2014)

Cloud Computing over Internet volunteer resources

Principal Investigators :

  • Dr. Arnaud Legrand, MESCAL project-team, Inria Grenoble Rhône Alpes
  • Dr. David Anderson, University of California Berkeley, Space Sciences Laboratory

Research objectives:

CLOUDSHARE investigates the use of cloud computing for large-scale and demanding applications and services over the most unreliable but also most powerful resources in the world, namely volunteered resources over the Internet. The motivation is the immense collective power of volunteered resources (evidenced by FOLDING@ home’s 3.9 PetaFLOPS system), and the relatively low cost of using such resources.

Scientific achievements:

The contributions of CLOUDSHARE were twofold. First, the team collected and archived traces, and developed software that facilitate their analysis and use (visualization and simulation). Second, building on the previous tools, the team developed models and algorithms optimizing the behavior of large-scale infrastructures.

Publications and Awards:

  • 6 Journal articles.
  • 2 Book chapters.
  • 5 Conference papers.
  • Failure trace archive at
  • Simgrid simulation framework at

Selected publication:

E. Heien, D. Kondo, and D. P. Anderson. A Correlated Resource Model of Internet End Hosts. IEEE Transactions on Parallel and Distributed Systems, 23(6), June 2012.

Follow up:

The collaboration with David Anderson and the BOINC (Berkeley Open Infrastructure for Network Computing) COMMUNITY is very fruitful. It has led to new collaborations with for example Rhonda Righter (University of California Berkeley) and Wenjing Wu (Chinese Academy of Science). Ongoing research directions include: BOINC as a storage facility and improving BOINC turnaround time.
