st: Stata 8 and Mac OS X

["Jeremy T. Fox" <jeremytfox@mac.com>]

I performed an analysis of this question in the email "Memory Truths by 
OS" about a week ago. Search for it in the archives.

But, the bottom line is that in practice you can get 2100M on set 
memory, 900M on set matsize, and you can easily max out set maxvar. 
This situation is actually much, much better than the Wintel platform, 
for reasons explained in this Stata FAQ:

http://www.stata.com/support/faqs/win/winmemory.html

The bottom line is that Stata requires contiguous memory spaces, so the 
total address size of any application is not the only criteria, but 
even there Mac OS X wins, as its total space is around 3.5G.

The answers will start to change with the April 22 release of 64-bit 
Linux for the AMD Opteron processors, and the expected fall releases of 
Windows XP 64-bit Edition for the AMD64 architecture, and 64-bit Mac OS 
10.3 Panther for the IBM PowerPC 970 chips.
However, I do not have the inside knowledge of these new products to 
predict how much contiguous memory will be available to a 32 bit 
program like Stata on them.
