Each individual CSS-AIMS run took about 100 hours on one core (Intel(R) Xeon(R) Gold 6152 CPU @ 2.10GHz CPU) to complete 60 ps dynamics. Consequently, the total computational cost of running 44 individual CSS-AIMS simulations, employing 22 cores (Intel(R) Xeon(R) Gold 6152 CPU @ 2.10GHz CPU), amounts to 8 days. Performed in the United Kingdom, these simulations have a carbon footprint of 356 kg CO2e (it would be 79 kg CO2e if performed in France). It is important to note that the CSS-AIMS dynamics converges rapidly, as stated above, and the cost of the CSS-AIMS simulation could have been dramatically reduced by only using 5 CSS-AIMS runs. This fast convergence is, of course, system-dependent, and it cannot be guaranteed that CSS-AIMS will converge rapidly in every case of long-time (weak-coupling) dynamics.
