[with spkg, positive review] upgrade atlas in sage to version 3.8.2

[was]

This is a non-negotiable blocker for Sage-3.1.

We need this for a quick build on the new sage.math hardware :)

Cheers,

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, 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 :)

Merged in Sage 3.2.3.final
