I added support for the AccFW for LinBox on OSX (it made it upstream) and had planned to add it to all the other packages in Sage that would benefit from it, but never went beyond LinBox in verifying which ones already do so per default and which ones need it added. Overall the AccFW seems fairly competitive, but I still want to run some benchmarks how it compares to the current release of ATLAS because things have been moving quite rapidly for ATLAS on the Core Duo support - it used to be that the 32 bit was faster than the 64 bit build, but that has been fixed and performance of ATLAS on Corep Duos improved by at least 80% in the last 3 months or so. I don't know if Apple has updated the AccFW in that timeframe. > > Cheers, > > Tim. > Cheers, Michael --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
