Let G = (V, E) be a graph on n vertices. A bijection f : V → {1, 2,. .. , n} is called a distance magic labeling of G if there exists an integer k such that u∈N (v) f (u) = k for all v ∈ V , where N(v) is the set of all vertices adjacent to v. The constant k is the magic constant of f and any graph which admits a distance magic labeling is a distance magic(More)
In this paper, a new parallel acoustic simulation package has been created, using the boundary element method (BEM). The package is built on top of SPECFEM3D, which is parallel software for doing seismic simulations, e.g. earthquake simulations of the globe. The acoustical simulation relies on a Fourier transform of the seismic elastodynamic data, resulting(More)
We propose a method of a parallel distribution of densely populated matrices arising in boundary element discretizations of partial differential equations. In our method the underlying boundary element mesh consisting of n elements is decomposed into N submeshes. The related N×N submatrices are assigned to N concurrent processes to be assembled.(More)
