These software packages are or will be developed in collaboration with some academic partners (LIP6, LaBRI, CPMOH, IPREM, EPFL) or in collaboration with industrial partners (CEA, TOTAL, EDF) in the context of their private R&D or production activities.

Fast Multipole with BLAS (FMB), developed in collaboration with P. Fortin (LIP6), is a high performance parallel implementation of the Fast Multipole Method for the Laplace equation. It is based on BLAS routines and on an hybrid MPIThread parallelization for both shared and distributed memory architectures (see Section 3.4 ).

For the materials physics applications, a lot of development will be done in the context of ANR projects (NOSSI and proposal OPTIDIS, see Section 4.2 ) in collaboration with LaBRI, CPMOH, IPREM, EPFL and with CEA Saclay and BruyèreleChâtel.

In the context of the PhD thesis of Mathieu Chanaud (collaboration with CEA/CESTA), we develop a new parallel plateform based on a combination of a multigrid solver and a direct solver (the PaStiX solver developped in the previous ScAlApplix projectteam) to solve huge linear systems arising from Maxwell equations discretized with firstorder Nédelec elements (see Section 3.3 ).

Finally, we contribute to software developments for seismic analysis and imaging and for wave propagation in collaboration with TOTAL (use of GPU technology with CUDA in the context of the PhD thesis of Rached Abdelkhalek) and with BRGM (use of PaStiX and MaPHyS solvers in the context of the PhD of Fabrice Dupros in collaboration with Dimitri Komatitsch of MAGIQUE3D project team).
