  A simple method for the parallelization of extensive air shower simulations
is described. A shower is simulated at fixed steps in altitude. At each step,
daughter particles below a specified energy threshold are siphoned off and
tabulated for further simulation. Once the entire shower has been tabulated,
the resulting list of particles is concatenated and divided into separate list
files where each possesses a similar projected computation time. These lists
are then placed on a computation cluster where the simulation can be completed
in a piecemeal fashion as computing resources become available. Once the
simulation is complete, the outputs are reassembled as a complete air shower
simulation. The original simulation program (in this case CORSIKA) is in no way
altered for this procedure. Verification is obtained by comparisons of
10^(16.5) eV showers produced with and without parallelization.
