sorry for spelling errors:
I have to make the same question again.
I have win XP 32 bit and 2 MB of memory.
With Stata9 I can allocate 1200 MB of memory but with Stata11 only 770
MB. This is a significant difference. I often needed 850-900 MB of
memory in my analyses, but can not do this with Stata11.
OK that I maybe can tweak some more memory by closing down unnecessary
processes, but that is not the point.
I think Stata should inform customers about the larger program
overhead in Stata11 that decreases the amount of memory that can be
allocated. This is a disappointment as I did not calculate that I need
to change OS to 64 bit and also order a 64 bit Stata11 in order to
make the same analyses I used to do with my old setting.
Or am I missing something?
With Stata 9 I can set memory to 1200 MB:
. set mem 1210m
op. sys. refuses to provide memory
r(909);
. set mem 1200m
(1228800k)
. memory
bytes
