Parameter: nwrite
Definition
Output period for the quantum impurity solvers.
Type
Integer
Default value
2000000
Component
ALL, except for the DAISY component.
Behavior
This parameter controls the output frequency of the quantum impurity solvers. The quantum impurity solvers will output the intermediate results to disk files and run-time information to the terminal for every nwrite Monte Carlo sampling step. As for the continuous-time quantum Monte Carlo impurity solvers, the so-called intermediate results mean the imaginary-time Green's function $G(\tau)$ and histogram for the perturbation expansion series.
Especially, as
\[\frac{\text{nsweep}}{\text{nwrite}} \geq 100,\]
the CT-HYB quantum impurity solvers will save the current diagram configurations to the solver.diag.dat file every nwrite Monte Carlo sampling step. Then, you can use the u_animator.py to make an animation movie.
Comment
When the data binning mode is activated (isbin = 2), then the nwrite and nsweep parameters rise tenfold.
See also isbin and nsweep parameters, solver.diag.dat file, script/u_animator.py tool for more details.
