The objective of this thesis is to use domain decomposition methods to develop new efficient methods for high performance computing and boundary integral equations. One can think of two approaches for domain decomposition. One can make a decomposition of the original domain where the solution is sought, a volume decomposition, and then formulate a boundary integral equation in each subdomain with some ways of coupling them. Or we could first set up a boundary integral equation and then apply a domain decomposition of the boundary, a surface decomposition. In the first approach, we show that the local variant of the multi-trace formulation, which is naturally well-adapted to parallelization, has optimal properties of convergence in the case ...
