I have never used the parallel stuff in ipython, but my understanding was that it was more for cluster-kind of stuff. This is getting significantly rewritten, also, so things are changing there. But the way most people use parallel stuff in numpy is: first use BLAS/LAPACK which is multithreaded, then use multiprocessing, etc... It depends on what you are trying to achieve, but my understanding is that as soon as you use arrays and the liked, clojure is not that helpful compared to a much more primitive runtime as python, because all the parallel goodies of clojure are not available anymore. But I have never seriously used clojure, so I may be dead wrong.
