I just uploaded new releases of M4RI and M4RIE to the M4RI website. Not much changed except that I implemented Strassen multiplication in M4RIE. The results are visualised below, where blue means M4RIE wins and red means Magma wins. The first two plots are for a Xeon (eno at UW) and the last two for an Opteron (prai243 at RHUL).
I’ve also updated the Sage package http://trac.sagemath.org/sage_trac/ticket/9562 such that it is easier to play around with the new code.
