This is a rather broad question, and I would suggest that you have (another?) close look at the parallel documentation. <http://docs.julialang.org/en/release-0.4/manual/parallel-computing/>The errors about functions not defined on worker processes e.g. suggest that you aren't using the @everywhere macro when defining functions (or using it incorrectly).
Without knowing more about what exactly you are trying to do this question is impossible to answer.
