I'm not an expert with triaxial test! You are. Question that you can help to answer is whether eigen vs. wm3 provide correct result ;-) Especially for clumps, because there were some clumps problems with eigen. I'm worried that one day we will once again see a clump rotating wildly with no apparent force that could cause this. > Yes, I experimented this multithread variability in different situations. I'm not bothered by the fact that different order of performing calculations leads to different results. That's normal. So I don't care that curves are different when jobs is not 1. As long is they are within a certain range, of course. To make sure that this is the case, we could run 1000 simulations using some python script, plot all the curves, and see that all of them are in fact generating a single wider curve that looks coherent. If the eigen - wm3 difference also fits within this wider curve, then I would assume that it's all correct. So I think that running 1000 tests on jobs=2,3,4,5 with both wm3 and eigen from a SINGLE .xml file, and checking if all those 2000 curves are similar to each other is the simplest way to verify correctness for now. I suppose that Vaclav could whip out such python script in no time ;) For me it would be longer to do :) -- Janek Kozicki http://janek.kozicki.pl/ | _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
