Paper Abstract:
|
This paper discusses how High Performance Computing can help to solve Engineering problems, where is necessary to reduce the execution time spent in the solution of sparse linear systems. We have chosen two free-distribution numerical parallel libraries called PETSc (Portable, Extensible Toolkit for Scientific Computation) and pARMS (Parallel Algebraic Recursive Multilevel Solver). Both libraries have been applied to a realistic test case of Nuclear Engineering where 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. |
