Is it a performance issue?

Yes. As Roman Leshchinskiy explained it's because parallel arrays are not fused properly yet. But it's quite trivial to modify Hpysics to use ordinary lists or arrays, and I think it'll give reasonable performance.

Personally I would not mind too much about performance initially; I'm very confident that lots of optimizations can be done afterwards - maybe even letting the GPU handle certain tasks.

I wouldn't mind too if it was just 'inefficient'; however, it's practically unusable. <> http://physics-dph.blogspot.com/2008/08/status-report-week-11-12.html -- Roman I. Cheplyaka :: http://ro-che.info/ "Don't let school get in the way of your education." - Mark Twain
