Abstract: In this work we present a library of parallel solvers based on the boundary element method (BEM). We provide a brief description of BEM and its parallelization, focus on SIMD vectorization and shared- and distributed-memory parallelization by OpenMP and MPI, respectively. Two approaches for distributed parallelization of BEM are discussed - the first one based on a novel parallel adaptive cross approximation (ACA) method, the second one on the boundary element tearing and interconnecting (BETI) domain decomposition method. To demonstrate the efficiency of the library we provide results of numerical experiments on the Xeon and Xeon Phi based clusters.
