Yes, I think so... on Linux. And I think we should start doing so. Clement and Michael A. did experiments with this before and it was very impressive. > I'm curious what the timing differences are between similar/same > hardware and using Sage's ATLAS versus the Apple ATLAS. That would be a great question to ask on the ATLAS list (if there is one) or ask Clint Whaley, since I bet they do so... > > Thanks, > > Jason > > > > > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
