Hi...

Depends on the application, not the OS.
If, for whatever reason, Stata can only do a single memory allocation only once, then so be it.
That's a limitation of the program, not the OS.
Normally though, if you run out of memory (like an array has gotten bigger), you can just allocate more to the app. Unless you have unusual virtual memory settings, you'll get what you need.

Hi there,

My colleague told me today that an IT guy once said to her that the
requirement of contiguous memory is unique to Stata, and there are
statistical packages which do not need that.  Before, I have always
thought that contiguous memory is needed for all sort of computing
programs and in the case of Stata, if there is a "contiguous memory
problem", then the OS is to be blamed.  I don't know where this guy is
or else I'd have hunt him down to grill him some more about this
comment, so I have to find out the answer on my own.

I hope I have framed my Q in here clearly enough.  Any input and
pointers to relevant info on the web would be greatly appreciated!!
TIA.

Regards,
Ada
