[Yade-dev] [Bug 1814052] Re: Unreproductible simulation (one core, one computer, one script) with a tutorial example
I think I have found the parameter which was making my simulation unreproducible : In the Pyrunner, the checker is working with "realtime"... I didn't know but this the CPU time which can vary in function of how my computer is busy. By replacing "realtime" by "iterPeriod", for a same packing loaded initially, the simulation is reproducible. ** Attachment added: "Script with a packing loading" https://bugs.launchpad.net/yade/+bug/1814052/+attachment/5234711/+files/simple_shear_script.py -- You received this bug notification because you are a member of Yade developers, which is subscribed to Yade. https://bugs.launchpad.net/bugs/1814052 Title: Unreproductible simulation (one core, one computer, one script) with a tutorial example Status in Yade: New Bug description: In the framework of my PhD thesis, I use Yade and shear numerical simulations.

Actually I cannot answer, I do not know sufficiently computers and Yade (not sure for instance there are not any part of the computation in parallel, even if Yade is launched on a singe core ...).
