I don't have anything to add regarding your experiments with
multiprocessing, but:

This seems like the kind of task NumPy <URL:http://www.numpy.org/> is
designed to address: Generating and manipulating large-to-huge arrays of
numbers, especially numbers that are representable directly in the
machine's basic number types (such as moderate-scale integers).

Have you tried using that library and timing the result?
