Hi (again Johan), For your information, we track/fix issue on big models by testing them in internal workbench. If you have simulation issue, we can add your model on this non-opensource set to try to improve the compilation time for it. Don’t hesitate to mail it to me (might be a partial or without parameter knowledge).
Regards, Clément From: users <users-boun...@lists.scilab.org> On Behalf Of Johan Lafitte Sent: Wednesday, February 10, 2021 6:41 PM To: users@lists.scilab.org Subject: [Scilab-users] xcos_simulate() Hi, My xcos model becomes quite large and takes time to compile. In order to launch batches and optimisation process, it seems possible to compile the model juste one time. However, I meet the same difficulties as described in this post : http://mailinglists.scilab.org/xcos-xcos-simulate-scs-m-1-or-xcos-simulate-scs-m-4-td4031207.html#a4031274">http://mailinglists.scilab.org/xcos-xcos-simulate-scs-m-1-or-xcos-simulate-scs-m-4-td4031207.html#a4031274 Indeed, the following script... ___________________________________ loadXcosLibs; importXcosDiagram("C:\Users\johan\OneDrive\Micro entreprise\Technique\Kayak guide\Modélisation\Scilab\optimisation"+"\modèle physique et commande simple_10_opti.zcos"); tic(); xcos_simulate(scs_m, 4); disp("méthode 2",toc()); tic(); %cpr = xcos_compile(scs_m); disp( "Durée compilation",toc()); tic(); xcos_simulate(scs_m,1) disp( "méthode 1",toc()); ___________________________________ ...gives the following results : ___________________________________ "scicos_simulate step 1" 50.813412 s "scicos_simulate step 2" 57.440604 s "xcos_simulate(scs_m, 4) méthode 2" 58.808546 s "Compilation duration" 55.615238 s "xcos_simulate(scs_m,1) méthode 1" 61.133700 s ______________________________ It seems the compilation step is done in all these cases. Thank you for your time and for your help Johan note 1 : when the final time of the simulation is set from 20s to 200s, the execution time increases about 15s note 2 : according to the windows task manager, CPUs seem to be used about 30% during compilation and about 100% during simulation which takes few seconds
