Abstract The present status of extensive air shower (EAS) simulation procedures is reviewed. The advantages of combining numerical and Monte Carlo methods for the description of EAS development are discussed. Physics content of cosmic ray interaction models is briefly described and their predictions are compared to the first LHC data. Finally, some outstanding puzzles related to cosmic ray composition at the “ankle” energies are analyzed.

Computer time optimization in Extensive Air Shower simulations.
It is proved that the computation time can be optimized in a controlled way that allows to know which are the minimum numbers of EAS to average, the thinning value to be considered, which will allow to obtain a convergent value of the desired physical observable related to the fluctuations between EAS.
