Monte Carlo simulations of star clusters with primordial binaries. Comparison with N-body s

We outline the steps needed in to calibrate the Monte Carlo code in order to perform large scale simulations of real globular clusters. We calibrate the results against $N$-body simulations for $N = 2500$, 10000 and for the old open cluster M67. The calibr
