Application of supercomputer computing environments for solving the volumetric singular integral equation of the diffraction problem on a dielectric body

In this paper the problem of diffraction of external electromagnetic field on locally heterogeneous body placed in free space is considered. The formulated problem is reduced to three-dimensional singular integral equation. The problem is solved using Galerkin numerical method and at the same time using the collocation numerical method. Because of high capacity the task solving was realized by Galerkin numerical method at various parameters with use of two types of software for supercomputing complexes: realization of MPI and realization of program system x-com. The features of performance of a task on a supercomputer complex are investigated.
