Hi, since 4.7 is about adding SPKGs I'm wondering if that could motivate someone to finish the review of
http://trac.sagemath.org/sage_trac/ticket/9562 which is about fast linear algebra over small extensions of GF(2). It was agreed ages ago that M4RIE (the new library which implements this functionality, started at a Sage Days workshop) should go in and as far as I know it builds on all platforms. As for the performance: multiplying two 1,000 x 1,000 matrices over GF(2^8) Sage 4.6.2 80.35 s NTL 5.4.2 127.43s # not sure why this is so slow Magma 2.15 1.68 s LinBox over F251 1.25 s M4RIE 0.53 s #9562 Btw. for those who are curious, I gave a talk about M4RI & M4RIE last week in LORIA, Nancy: http://martinralbrecht.wordpress.com/2011/03/30/talk-about-m4ri-and-m4rie/ Cheers, Martin -- name: Martin Albrecht _pgp: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8EF0DC99 _otr: 47F43D1A 5D68C36F 468BAEBA 640E8856 D7951CCF _www: http://martinralbrecht.wordpress.com/ _jab: martinralbre...@jabber.ccc.de -- 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
