Re: [Yade-users] [Question #225080]: Many scenes syncronization
Question #225080 on Yade changed: https://answers.launchpad.net/yade/+question/225080 Status: Answered = Open ceguo is still having a problem: Thanks Bruno, I got your idea for multithreading and now I'm trying to implement your idea. Everything goes well except that I save a temporary simulation setup using Omega().saveTmp() and later I want to use Omega().loadTmp() to load it. For one threading it's no problem. But how to access the memory in multiprocessing? Another alternative is to save to hard disc using save() and load(), which will be more expensive. I have little experience in parallelization. Hope anyone can offer help. tks, Ning -- You received this question notification because you are a member of yade-users, which is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
Re: [Yade-users] [Question #225080]: Many scenes syncronization
Question #225080 on Yade changed: https://answers.launchpad.net/yade/+question/225080 Status: Open = Answered Bruno Chareyre proposed the following answer: Interesting question. I would think this is where independant processes (my example) differs with multithreading, since memory is not shared in the first case. One way to solve your problem, even in the first case, would be to manipulate the saved state in the main script. I'm sure it is possible, although I can't tell you exactly how to achieve this. You need to skip that part writing to the HD when saving a simulation. Maybe inspecting how saveTmp() works would give you an idea. -- You received this question notification because you are a member of yade-users, which is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp

Question #225080 on Yade changed: https://answers.launchpad.net/yade/+question/225080 Status: Open = Answered Jan Stránský proposed the following answer: Hi Ning, it is not possible in current implementation.. O.run() always run only current scene. For the behavior you proposed, some more implementation would be needed.. Jan 2013/3/25 ceguo question225...@answers.launchpad.net New question #225080 on Yade: https://answers.launchpad.net/yade/+question/225080 Hi, Following the question 216997, I have many scenes in yade by using O.addScene(). Now if I use O.run(stepno) without O.wait(), I can go to other scenes and run O.run(). Is this a possible way to parallel many scenes simulation? If luckily YES, what is the best way to synchronize these simulations? For example, I want each scene to run 1000 steps and return the stress after finishing. tks Ning -- You received this question notification because you are a member of yade-users, which is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp -- You received this question notification because you are a member of yade-users, which is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
