Certainly.
I am thinking to upgrade my desktop to 64bit cpu with 16GB memory to handle
large astronomical images and data. I wonder if
1) the latest numarry (besides 2d slicing) has been tested with one or more
64 bit CPU and Linux distributions
2) with 64 bit address space, will numarray be able to h
thanks, i ran it -- the only difference i got was the numarray version:
1.1.1 on the 686, and 1.3.3 on the 64bit... but i wouldn't have thought
that would make too much difference.

Do you have a simple program that demonstrates the problem?
I have an x86 machine with Python 2.3, and an x86_64 machine with Python 2.4
available. I wrote a simple test program which performs a slice operation,
but it behaves the same on both platforms.
Here's the program:
