This paper presents the first parallel implementation of novel “Interpolated Factored Green Function” (IFGF) method introduced recently for accelerated evaluation discrete integral operators arising in wave scattering and other areas (Bauinger Bruno, Jour. Computat. Phys., 2021). On basis hierarchical IFGF interpolation strategy, proposed (hybrid MPI-OpenMP) results efficient data communication...

Computation of the Schrodinger equation energy levels is very important in physics. For example we can use these levels to calculate the absorption coefficient and light refraction in a material as well as calculation of the interband and intersubband transition energies. Density of states of the system can also be obtained by using the energy levels. Thereafter we can determine that the system...
