In the last post I showed how to use purrr to perform a simple Monte Carlo simulation. Since simulation studies are usually computationally expensive, it is benifical to write efficient code and make use of parallelization. The latter even more important when working on a modern computer. My PC has a Ryzen 3700X CPU with 8 cores and 16 threads. For longer computations it would be a waste of ressources not to go parallel when possible.
