Random number generators discussion

a SIMD-oriented Fast Mersenne Twister was recently published by Mutsuo Saito and Makoto Matsumoto (<http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/SFMT/index.html>). Do you know by any chance how this version compares speedwise to your own assembly language implementation (i.e. double MersenneRandom())?

Thanks,
Holger
