Abstract de la publi numéro 5404

here has been much work over many years on sparse matrices that has given rise to the production of several software packages. The goal of the GRID-TLSE project is to design an expert site that provides a one-stop shop for potential users of sparse codes. We will describe the main features of the expert site and some of the difficulties arising from exploiting a computational grid.
