  • Milestone changed from sage-3.4 to sage-3.2.3
  • Summary changed from upgrade atlas in sage to version 3.8.2 to [with spkg, needs review] upgrade atlas in sage to version 3.8.2

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 :)
