All keywords needed to run the calculations are passed to atomate2 through the user parameters argument and kpt settings, which are Python dictionaries. The default relaxation method used is the trust radius method (trm) with a maximum allowed force of 1 meV Å-1 . When running multiple related (same material or molecule) calculations, the atomate2 interface allows for both parallel and serial execution of this job via the run aims and run aims socket functions, respectively. The advantage of using the run aims socket function is that it uses the i-PI interface in FHI-aims and the ASE SocketIOCalculator to initialize the electron density to the converged value from the previous calculation when possible, reducing the total number of SCF iterations by a factor of two.
