SParC-LES

摘要: We discuss the design and development of a parallel code for Large Eddy Simulation (LES) by exploiting libraries sparse matrix computations. formulate numerical procedure LES turbulent channel flows, based on an approximate projection method, in terms linear algebra operators involving matrices vectors. Then we implement using general-purpose as building blocks. This approach allows to pursue goals such modularity, accuracy robustness, well easy fast exploitation parallelism, with relatively low coding effort. The developed this work, named SParC-LES (Sparse Parallel Computation-based LES), exploits two libraries: PSBLAS, providing basic Krylov solvers, MLD2P4, suite algebraic multilevel Schwarz preconditioners. Numerical experiments, concerning simulation flow plane channel, confirm that can achieve satisfactory performance. supports our opinion software methodology used build yields very good tradeoff between computational power computers amount
