Description
We present a highly parallel version of the boundary element
method accelerated by the adaptive cross approximation for the
efficient solution of scattering problems with composite scatterers. Individual
Calderón projectors are treated independently, i.e. the boundary
of every homogeneous subdomain is decomposed into clusters of elements
defining a block structure of the local matrix. The blocks are distributed
across computational nodes by a graph algorithm providing a load balancing
strategy. The intra-node implementation further utilizes threading
in shared memory and in-core SIMD vectorization to make use of all
features of modern processors.
