Hi all, I worked on some optimizations of contact detection recently and I would like to get feedback from you to detect possible bugs and confirm the speedup for different applications. If everything is ok, the changes can be part of the next release after some code cleanup and documentation.
If you have a chance, could you please download and compile the branch lp:~bruno-chareyre/yade/collide2 (bzr checkout lp:~bruno-chareyre/yade/collide, cd yade, scons, as usual) and try this with your own problems? I would be gratefull if you could report differences in terms of computation speed. I don't expect big improvements for small quasistatic problems. The speedup is more likely to happen on large and/or dynamic problems, where it should range between x2 and x3, or even more in multithread. Some results are reported here: https://yade-dem.org/wiki/Colliders_performace#Improved_InsertionSort Thanks.
