In part the answer depends on what definition of integrable you use. However,
it is not hard to come up with a Hamiltonian that is not integrable under any (
reasonable ) definition of the word integrable. What I would like try to do is
integrate the hamiltonian of some molecule using a symplectic numerical
integrator running on several loosely coupled processors. My problem is that I
have no idea what a hamiltonian for a real life molecule looks like.
