Does it work on mod.math.washington.edu? I tried sage: a = random_matrix(RDF,1000) sage: time b = a*a Time: CPU 0.43 s, Wall: 0.43 s and clearly ATLAS is *NOT* being multithreaded. However, if I do the same on my little OS X laptop, I get: sage: a = random_matrix(RDF,1000) sage: time b = a*a Time: CPU 0.45 s, Wall: 0.13 s # <--- look at that walltime! which is clearly multithreaded. - William > > -- > 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 -- William Stein 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
