Recent years have witnessed the emergence of galaxy clusters as a powerful cosmological probe. However, the current cluster-based cosmological constraints are limited by uncertainties in cluster astrophysics. In order to exploit the statistical power of the current and upcoming X-ray and microwave cluster surveys, it is imperative to improve our understanding of the structure and evolution of the hot X-ray emitting gas in galaxy clusters. In this talk, I will discuss recent advances in computational modeling of galaxy cluster formation, with highlights on both successes and challenges and a strategy for controlling astrophysical uncertainties.
