Fast solution of electromagnetic scattering problems using Xeon Phi coprocessors

Electromagnetic scattering problems can be solved by discretizing and transforming integral equations into matrix equations using the method of moments. In large-scale problems, the problem cannot be solved directly and needs to be solved using iterative methods, which use matrix vector products (MVP) to perform the iterative convergence to the solution. An efficient parallel implementation of MVP over Intel Xeon Phi coprocessor is proposed in this paper to speed up the solution of the scattering over a generalized minimal residual method. Using these manycore integrated processors, we can solve an electromagnetic scattering three-dimensional problem improving runtime on a coprocessor system.
