It can, depending on the use case: -- It can remove a lot of uneccessary temporary creation. -- IIUC, it works on blocks of data at a time, and thus can keep things in cache more when working with large data sets. -- It can (optionally) use multiple threads for easy parallelization. All you can do is try it on your use-case and see what you get. It's a pretty light lift to try. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [email protected] _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
