Re: [Yade-users] [Question #279359]: MakeCloud() single-threaded?
Question #279359 on Yade changed: https://answers.launchpad.net/yade/+question/279359 Status: Open => Answered Bruno Chareyre proposed the following answer: makeCloud() is a function, not an engine, therefore it can't be used in ParallelEngine. More generally, parallelizing an algorithm needs low level implementation (domain decomposition especially), so you don't usually get things parallelized magically by playing with high level commands. This being said, you can of course run many makeCloud()s in parallel. There are python libs for that. But designing the domain decomposition and the subtasks and assigning them to different cores is entirely on your shoulders, Yade will not help.

Question #279359 on Yade changed: https://answers.launchpad.net/yade/+question/279359 Status: Answered => Open Gary Pekmezi is still having a problem: Thanks for your reply Christian. That is what I suspected. One more question along the same veinCan makeCloud be used in ParallelEngine(). I can maybe subdivide the domain in a semi-rational way if that is the case.

[Yade-users] [Question #279359]: MakeCloud() single-threaded?
New question #279359 on Yade: https://answers.launchpad.net/yade/+question/279359 I noticed that when I run a triaxial test (either with a preprocessor or a script), TriaxialStressController() and TriaxialCompressionEngine() make use of all the cores specified via the -jN command. However, MakeCloud() is using a single core. Is this inherent to the algorithm?
