  Self-organized patterns of cathode spots in glow discharges are computed in
the cathode boundary layer geometry, which is the one employed in most of the
experiments reported in the literature. The model comprises conservation and
transport equations of electrons and a single ion species, written in the
drift-diffusion and local-field approximations, and Poisson's equation.
Multiple solutions existing for the same value of the discharge current and
describing modes with different configurations of cathode spots are computed by
means of a stationary solver. The computed solutions are compared to their
counterparts for plane-parallel electrodes, and experiments. All of the
computed spot patterns have been observed in the experiment.
