5.3. Directed loop algorithm solvers, dla_H
and dla_B
¶
dla_H
and dla_B
are quantum Monte Carlo solvers with the directed loop algorithm.
They take an input file as the command line argument.
dla_H
is for spin system and dla_B
is for Bosonic system.

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.
