without pqs (three runs): Computation time: 370.939 seconds Computation time: 382.615 seconds Computation time: 360.418 seconds
with pqs - and extra constructor calls, which would be avoided if I converted whole data structure! (three runs): Computation time: 415.724 seconds Computation time: 423.181 seconds Computation time: 421.799 seconds
that makes a difference of roughly 11% - 13%
oops. I did not pay attention to optimization level when compiling yade. I have redone checks with maximum optimization (-O3). Six runs with and six without pqs. Averaged result is now just 2% performance drop. I'm really sorry for that misinformation. -- Janek Kozicki |
