Since the last decade, most of the supercomputer architectures are based on cluster of SMP nodes. In those architectures the exchanges between processors are made through shared …

In this paper, we consider a hyperbolic system with multiple time step characteristics. Such a situation arises for example in combustion problems when the acoustic time is small …
Solving large sparse linear systems by iterative methods has often been quite unsatisfactory when dealing with pratical \"industrial\" problems. The main difficulty encountered by …
The purpose of our work is to provide a method which exploits the parallel blockwise algorithmic approach used in the framework of high performance sparse direct solvers in order …
PaStiX is a scientific library that provides a high performance direct supernodal solver for very large sparse linear systems. It relies on a block factorization based on an …
