Using multiprocessing is fine. That starts up multiple interpreters in *different* processes. Yang is using a non-Python program that embeds the CPython interpreter and starts up multiple copies of it in the same process. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
