[Bruno Chareyre <bruno.chareyre@xxxxxxxxxxx>]

Hello there,
The collision detection of yade can now run in parallel with openmp [1].
The difference will be visible or not depending on the type of
simulation one is doing [2].
In many cases contact detection is not the big part of cpu time
(typically, quasistatic situations will less than 100k particles), hence
no significant speedup is to be expected.
Some benchmark tests have been reported [3].
Please let us know if you find any bad/good effects of this change in
your simulations by replying in this thread.

Best regards.

Bruno
