Computational cost is not an issue for DC-FSSH. On average, a single DC-FSSH trajectory takes on average 2.5 hours to complete a 100 ps simulation on a single core (Intel(R) Xeon(R) Gold 6152 CPU @ 2.10GHz CPU) machine. Based in France, the total simulation of 2000 DC-FSSH trajectories up to 100 ps has a carbon footprint of 2.70 kg CO2e. The leading cause of the discrepancy between the run time of a DC-FSSH trajectory and a CSS-AIMS simulation is that in the latter, on average, 25
