[ODE] ODE announcement: new iterative solver

[Joakim Eriksson]

Great job on the iterative solver. Going to be intresting to see some
performance figurures on it. The alorithm also seems to be SSE / SSE2
friendly so some cpu specific optimizations could probably increase the
speed of that algorithm a bit. Throw in some good prefetching and there
might get even better.

What book would that be that your refering to? He has produced a number
of them and also some papers on the subject.
