Stéphane Genaud

From sep. 2007 to sep. 2009, visiting researcher at INRIA Nancy-Grand Est research center. I have now returned to the University Strasbourg, in the LSIIT laboratory (CNRS-UdS), ICPS team. I am also an associate member of the AlGorille team project.

Research area

Topics of interest - Grid Computing. Parallel application design for efficient execution on grids. MPI enhancements for grids. Load-balancing techniques for heterogeneous platforms. Fault-tolerance for parallel applications. Peer-to-peer concepts applied to parallel computing.

Research projects

P2P-MPI : our own Grid middleware, can transparently find processors to run a parallel applications. The application must be developed in Java, using the P2P-MPI message passing library which conforms MPJ. P2P-MPI is oriented to desktop grids: no admin privilege is needed to install or run it. Further, a transparent mechanism for fault-tolerance through replication of processes is integrated to increase application robustness.

Parallel applications : we help in the design of parallel applications for grids in various scientific fields. Currents projects are:

• Ray2mesh (2000-2006) is a high performance set of software tools for seismic tomography whose objective is to compute a realistic Earth model. We use massive quantities of seismic waves records to ray-trace waves propagation inside a global Earth mesh with thin cells. We then refine the mesh by adapting cell sizes to improve the information quantity and quality contained in each cell.
  
• USS-SimGrid project (2009-2011) aims to improve and extend the SimGrid simulation toolkit.
  
• SPADES project (2009-2011) aims design and build a highly dynamic environment allowing users to take advantage of high-end computing devices enrolled in a very large scale infrastructure without disturbing their native use.
