#include <triqs/mc_tools/mc_generic.hpp>
Synopsis
int run (int64_t n_cycles,int64_t length_cycle,std::function<bool ()> stop_callback,bool do_measure,communicator c = mpi::communicator{})
Generic function to run the Monte-Carlo. Used by both warmup and accumulate.
Parameters
- n_cycles Number of QMC cycles
- If negative, the accumulation is done until the stop_callback returns true or signal is received.
- length_cycle Number of QMC move attempts in one cycle
- stop_callback A callback function () -> bool. It is called after each cycle
- to and the computation stops when it returns true. Typically used to set up the time limit, cf doc.
- do_measure Whether or not to accumulate for each measurement
- c The mpi communicator [optional]. If not provided use the default-constructed one.
Returns
0 if the computation has run until the end 1 if it has been stopped by stop_callback 2 if it has been stopped by receiving a signal
