I am a bit worried about the differences in results. Just to be sure
you are comparing apples with apples, it may be a good idea to set the
seed at the beginning:
np.random.seed( SEED )
where SEED is an int. This way, you will be inverting always the same
matrix, regardless of the Python

Without much detailed knowledge of the topic, I would expect both
versions to give very similar timing, as it is essentially a call to
ATLAS function, not much is done in Python.
Given this, maybe the difference is in ATLAS itself. How have you
installed it? When you compile ATLAS, it will do

Hi,
win32 do not mean it is a 32 bits windows. sys.platform always return
win32 on 32bits and 64 bits windows even for python 64 bits.
But that is a good question, is your python 32 or 64 bits?

The python3 version is compiled without any optimised library and is
falling back on a slow version. Where did you get this installation from?
