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.
