I just installed XP X64 edition on a spare Thinkpad (T61) to see how it
runs--it seems much faster and more stable than VISTA 64-bit (on a clean

It will take some effort to hunt drivers down of course (as it is known that
hardware manufacturers have not done much to support XP X64 edition and MS
is "demoting" it).  

Does (or has) anyone run STATA 10/MP (64-bit) on XP X64? 

 Is it possible to do so?

Hi all -

I'm running Stata 10 64-bit on a 4-core processor with 8 gig of RAM.  My
is valid for 2 processors.  I am doing a rather large and time-consuming
constrained nested logit model with a large number of alternatives, and have
been experiencing 48 hour times until convergence.  

Before upgrading to Vista SP1, the cpu utilization monitors would show all
processors in use and an overall utilization of 50% while running large
problems, which is what I would expect since the program is constrained to 2
cores by my license.  Since the Vista service pack update, and probably a
update too, I am now observing utilizations bouncing between 35 and 50
averaging about 40 percent.  Execution is taking noticeably longer.

Have others experienced a loss of multiprocessor efficiency with recent
Is there a fix?  On a separate but related note, can I set processor
affinity in
stata to force execution to stay on two specific cores, since swapping cores
must involve additional system overhead?
