The spkg at
http://sage.math.washington.edu/home/mabshoff/spkgs/atlas-3.8.2.spkg
fixes the following problems:
- update to 3.8.2
- better detection of Pentium D and E
- detect more Core2Duos cores
- properly detect Dunnington cores
In addition the spkg has been cleaned up. Build time:
- on the new sage.math down from 180 minutes to
real 11m36.903s user 9m58.840s sys 1m17.870s
- On cleo/iras, i.e. Itanium2 machines on SkyNet?:
real 37m34.354s user 34m18.232s sys 1m20.748s
This also fixes #3787
Cheers,
Michael

Michael, do I have to wait until there's a 3.2.3.alpha before testing this? I have been using 3.2.2 for a while now. John

This can be tested with any recent Sage release. William did some complete build of Sage with this ATLAS.spkg, so hopefully it will get a review soon :)
