There will be a version of Stata 9 that will have SMP capabilities; it is
under active development.  We do not yet have a release date; we are guessing
it will be available either late this year or early next.  It will be an
extra-cost feature along the lines of Stata/SE.  When the SMP version becomes
available, you will be able to convert your Stata 9 license to the SMP license
for the price difference.

SMP stands for Symmetric Multi Processor.  SMP computers have multiple 
CPUs (either on the same chip or on multiple chips), and share memory 
and other components.  The idea behind an SMP-version of Stata is to 
exploit those multiple CPUs to carry out calculations in parallel.

Our experience suggests that he is right.  We have been working with Windows
and Linux and Sun.
