The computational system is the Ti metal (001) surface containing 72 atoms, and molecular dynamics simulations were performed on it with a timestep of 500 steps and a frequency of 1 fs. The simulation was conducted on a single node with 32 cores and 64 GB memory. After running for two days, only 260 steps were completed, and the task was unexpectedly interrupted. Can the efficiency of Abacus molecular dynamics simulations be improved?
