yang yi posted a new comment: Janek Kozicki (cosurgi) , Jan Stránský (honzik) , Bruno Chareyre (bruno-chareyre) Thank you very much for answer my question. According to your suggestion, I checked the server like this (1) Run yade by the command: ~/myYade/install/bin/yade -j90 20200522.py (2) Start the script by the 'start' button on the Controller(), without "3D" show (3) I did 10 iteration test and the time result as follows PC: -j8 39.45s \ 47.79s Server: -j32 26.1s -j48 24.51s -j50 25.32s -j52 24.55s -j60 26.53s -j88 23.29s \ 23.12s -j90 23.27s \ 23.72s -j92 23.05s \ 23.76s \ 24.24s \ 24.09s -j94 23.48s -j96 23.91s Because I get the time by hand, so there is errors. The results seems that the server is faster than PC without 3D show and the -j92 or -j90 maybe the optimal jobs. (4) I used the command : yade --stdperformance -j8 to test the performance But I just to guess the result, I wirte as below -j8 1465.98 iter/s -j48 1386.40 iter/s -j88 1427 iter/s -j90 1279 iter/s 1467 iter/s -j92 1385 iter/s -j96 1313 iter/s I find the number is unstable. It seems that -j90 is the best. (5) For the above test, I guess that: The before test, I take 3D show, the server is slower than PC very slowly, that is becuase the GUI is depend on just one core of the CPU. For one core of I7-9700k 3.6GH is better than 6146 , 3.2GH. IF my guess is right or not? (6) I have two questions: 1) It looks that the falling speed of particles and the roation speed of the plank in the 3D show are different, if the I modify the number of the particles. So in the Server, I hope to check if the rotation speed matches the falling speed of particles or not. The direct way is the 3D show. However, if 3D show is used, the speed is very very slow. my question is : if I close the 3D show, the speed of the plank and particles are the same with 3D show open or not? 2) If the speed of plank and particles are not depend on the 3D show. I will storage the bodies' location of the simulation process, and replay the locations after the simulation is over. my question : is there a better way to do that?
