Dear SIESTA developers Actually I tested the memory usage with the SZP basis against the SZ basis. For the bulk Si, SZP calculations require twice as much memory as the SZ calculations. However for the nanowire (2600 atoms), the memory usage jumps from 3.4 GB to more than 14GB! Is it normal? Please give me some hints!
