Module mcmc_mpi

source code

This is a helper module to make use of mcmc.py and mcmc_big.py. It allows you to conveniently run a Monte-Carlo simulation of any kind until it converges (stepper.run_to_bottom) or until it has explored a large chunk of parameter space (stepper.run_to_ergodic).

It also helps you with logging the process.

When run in parallel, each processor does its thing more-or-less independently. However, every few steps, they exchange notes on their current progress. If one finds an improved vertex, it will be passed on to other processors via MPI.
