hello FRanck,
i haven't tested physigs yet (i probably missed the announcement), but it look
great.
but why would link has to be computed in message?
it is look very unoptimized...

Maybe you'd like to test my [physigs] abstraction? It's a pure vanilla
particle simulation that uses dsp objects to drive the mechanics and
stores everything in tables, so you always know the particle order. And
if you only need the order to be able to store positions in tables,
well, they are already in tables, so you don't need to do any copying.
[physigs] has shown comparable speeds with pmpd in my tests. It's a bit
thwarted by the calculation of links which has to fall back to message
computations, but maybe you don't use links? :)
Get it at http://github.com/footils/physigs and read my paper on the
LAC2010 site: http://lac.linuxaudio.org/2010/?page=program
Ciao
