This sounds like 32 bit -- have you tried a 64 bit Python_numpy? Nt that you wont have issues anyway, but you should be abel to do better than 1.3GB... > memmaps are also limited to RAM, I don't think so, no -- but are limited to 2GB (I think) if you're using a 32 bit process There is also a compressed array package out there -- I can't remember what it's called -- but if you have large compressible arrays -- that might help. -CHB -- 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]
