[SciPy-user] Enthought Python, build 1069, atlas?

[Joe Cooper]

Hi Yichun,

Atlas is not included in the the Enthought Edition Python.  SciPy and 
most other components that support it, are built using atlas, but the 
libraries/headers themselves are not included.  It's a difficult project 
to distribute (and to use for building in general) because its 
performance is closely tied to the platform it is built on.  Most folks 
using the Enthought Edition Python are not building software, but want 
an "everything I need is already built, so I just write in Python" 
package, so I've never had a request to include it and it would be 
difficult to convince me to include it.  ;-)

It's probably best if you do build your own atlas, if you're building 
software that depends on it.  The Atlas developers seem to believe very 
strongly that a tuned atlas can make huge differences in the performance 
of the software you build.
