Abstract

Over the past years, we have developed several parallel implementations of the MLFMA in two and three dimensions, for the broadband EM characterization of large structures. We have reviewed how the hierarchical partitioning can result into scalable algorithms. Asynchronous techniques allow for the simulation of problems with a large number of dielectric objects. Experiments indicate that large scale simulations of over 512 cores are now possible.
