We develop parallel program for numerical simulation of the interaction of intense laser pulses with manyelectron atoms on the basis of the time-dependent Kohn-Sham equations. It is shown that the use of modern computer clusters makes it possible to solve these equations for a wide class of atoms in a relatively small time, determined by the parameters of the laser pulse and electronic configuration of the atom. High accuracy of the numerical code is demonstrated on the example of calculating the high-frequency spectrum of electron current excited during ionization of noble gas atoms by few-cycle laser pulse.
