Abstract
This paper discusses a time domain fast boundary integral equation method for three dimensional elastodynamics and its parallelisation for a large shared memory parallel computer. Some details of the PWTD (Plane Wave Time Domain) approach and an extension of the theory to the anisotropic case are presented. We then examine the parallelisation strategies of the code using OpenMP and MPI-OpenMP hybridisation. In the case of MPI-OpenMP hybrid parallelisation, a numerical example with more than one million spatial DOF is shown. It is concluded that the method is promising, its parallelisation with OpenMP is effective and that larger problem can be analysed with MPI-OpenMP hybrid parallelisation.
