Hi all, I had a question/comment from a numpy/Scipy developer that I was asked to forward on:

Is there much point? Are there any 64bit Intel Macs? What difference might a 64bit build make on a G5? For the app in mind, this is the issue: I am interested in 64-bit because it is supposed to be able to open >4GB data files in memmap mode (that is, you could treat any large data set like a normal numpy array and *instantaneously* access sub-data without ever loading the entire file. Note that this works even with small amounts of physical memory, only the (theoretical) memory address space has to be 64bit.) thoughts? -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] _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
