Four controlled identical realizations of a galaxy-cluster zoom-in simulation reveal 10-25% variability in galaxy masses driven by stochastic processes and modulated by feedback, establishing a noise-dominated but statistically reproducible regime at low resolution.
GPU version of OpenGadget3 matches CPU results across multiple test suites with chip-to-chip speedups of 2-5x.
