    The simulations were run on the supercomputer Jean-Zay (GENCI–IDRIS) on NVIDIA V100 GPUs over a ∼3 yr period, under the time allocations Grand Challenge-101470 (08/2020), A10-A0100412451 (05/2021), and A13-A0130412451 (11/2022). The entire set of simulations was run for a total of ∼350 000 GPU hours. A typical simulation with 250k stars took approximately 20–50 days with 4–16 GPUs, while the largest 1.5M star simulation took ∼400 days with 12–48 GPUs. The total CO2 equivalent consumption for our simulations is ∼9 tons of CO2,eq.
