4.5. Directed loop algorithm solver dla

dla is a quantum Monte Carlo solver with the directed loop algorithm. This takes an input file as the command line argument.:

$ dla param.in

DSQSS/DLA implements random number parallelization by using MPI. Since each process performs NSET Monte Carlo calculation independently, the total number of MC sets increases $N_{\text{process}}$ and thus it is expected that the statistical error also reduces to $1/\sqrt{N_{\text{process}}}$ times.
