This paper discusses how High Performance Computing can help to solve Engineering problems, where it is necessary to reduce the execution time spent in the solution of sparse linear systems. We have chosen three free-distribution numerical parallel libraries called PETSc (Portable, Extensible Toolkit for Scientific Computation) [Satish2001], pARMS (Parallel Algebraic Recursive Multilevel Solver) [Saad2003], and one direct sparse solver named SuperLU [Demmel2003]. These libraries have been applied to a realistic test case of Nuclear Engineering where it is necessary to solve efficiently very-large sparse linear systems to study steady-state neutron diffusion processes. Numerical experiments have shown the effectiveness of using parallel and distributed computing.
