I have set up a Brownian dynamics optimizer as follow:

bd=IMP.atom.BrownianDynamics(m)
bd.set_maximum_time_step(1000)

      e = bd.optimize(10)


Is it possible in IMP to parallelize the code to make it faster?
If you really require the output of one optimization to be the input of the next, then no, short of parallelizing the restraint evaluation itself. Currently the only way to do that is via OpenMP.
If you can instead run nrounds optimizations starting from different (e.g. random) starting conditions, parallelization is trivial. You can use IMP.parallel or simply run multiple copies of your script, e.g. with different random seeds.
