Currently I'm trying to optimize SOR_LCP solver with SIMD. I profiled 
test_crash example with about 1800 boxes and more than 80% of simulation 
time was spent in this solver. The main problem that I hit was data 
misalignment, but this should be easy to resolve (I hope ;)).

I'm also thinking about another approach - maybe better - moving the most 
expensive computations from this solver to GPU.

Best regards
