Today at Sage Days we tried slices on a few large arrays (no mmap) and found that slicing breaks on arrays somewhere between 2.0e9 and 2.5e9 elements. The failure mode is the same, no error thrown, basically nothing happens
This was on one of the big sage machines. I don't know the specific OS / CPU but it was definitely 64 bit and lots of available memory etc. -glenn On Thu, May 14, 2009 at 7:54 AM, Gael Varoquaux < gael.varoqu...@normalesup.org> wrote: > On Thu, May 14, 2009 at 07:40:58AM -0700, Glenn Tarbox, PhD wrote: > > Hum, I am wondering: could it be that Sage has not been compiled in > > 64bits?
