A User Friendly Toolbox for Parallel PDE-Solvers
Manfred Liebmann · 2006
The parallelization of numerical algorithms is required to run large scale simulations on clusters of high performance servers. This paper presents a detailed approach paralleliz-ing simulations based on the finite element method. The focus will be on the design of the communicator class, which provides an easy to use interface to all communication functions, that are required for the implementation of parallel linear algebra routines. Benchmarks for a parallel conjugate gradient algorithm on different cluster machines with Infiniband and Gigabit networking validate the parallelization approach. 1
