Grid computing - I manage the TAG project. The project started in July 2001 and aims at developping techniques needed to improve and ease the use of applications on computational grids.
We have first focused on source code transformations on MPI applications designed for paralell computers so as to enable their executions on computational Grids. The objective is to improve performances of some test-case applications when porting them to such heterogeneous environments. Experimental results with Globus have been reported papers.
Another activity is the development of our own Grid middleware named P2P-MPI. P2P-MPI gives its users the ability to transparently find processors to run their 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 make applications more robust.
Parallel applications - I participate to the development of a high performance set of software tools for seismic tomography : ray2mesh (short or long description). The objective is to compute a realistic Earth model using seismic tomography. 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.
