#include <triqs/mc_tools/mc_generic.hpp>
Synopsis
int warmup_and_accumulate (uint64_t n_warmup_cycles,uint64_t n_accumulation_cycles,uint64_t length_cycle,std::function<bool ()> stop_callback,MCSignType sign_init,communicator c = mpi::communicator{})
Warmup the Monte-Carlo configuration and accumulate/measure
Parameters
- n_warmup_cycles Number of QMC cycles in the warmup
- n_accumulation_cycles Number of QMC cycles in the accumulation (measures are done after each cycle).
- 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.
- sign_init The sign of the initial configuration’s weight [optional]
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
