Parallel ADI and CG methods based on the time-linearization of the three-dimensional, reaction-diffusion equations which govern the propagation of spiral waves in excitable media, have been implemented on both shared- and distributedmemory computers. ADI has been implemented by means of a dynamic block cartesian decomposition and its efficiency tends to that of the CG technique as the mesh is refined. The largest efficiency of CG was obtained on an Origin-2000 with a message passing model, private memory and 16 processors, and the efficiency of CG is larger than that of ADI.
