The results may not be bit-by-bit equal because different OSes use different
libraries and sometimes have difference processors. Results SHOULD be the
same to within numerical precision/roundoff considerations. If that's not
the case, it's possible you get very different answers if you are working
with a very ill-conditioned matrix, for example. So, without the details,
it will be hard for anyone reading this thread to help you out precisely.
