The time-domain BEM for the wave equation in acoustics and electromagnetism is used to simulate the propagation of a wave with a discretization in time. It allows to obtain several frequency-domain results with one solve.
In this thesis, we investigate the implementation of an efficient TD-BEM solver using different approaches.
This system is naturally computed using the sparse matrix-vector product SpMV.
We show that this operator is not appropriate for our problem, and we then propose to reorder the original computation to get a special matrix structure. The resulting solver is parallelized with a hybrid strategy above heterogeneous nodes and relies on a new heuristic to balance the work among the processing units.
Due to the quadratic complexity of this matrix approach, we study the use of the fast multipole method FMM for our time-domain BEM solver. We investigate the parallelization of the general FMM algorithm using several paradigms in both shared and distributed memory, and we explain how modern runtime systems are well-suited to express the FMM computation.
