The collider can be optimized by tracking displacements of particles instead of recording max velocities, and also by a series of fixes in different places. Collider speedup is up to a factor 2 in some cases (e.g. Sergei's dynamic cloud above) compared with default collider behaviour in r2813. The gain in cpu-time is around 30% max ( Sergei's script, 125k spheres, 4 threads).
Quick question for branch experts: what is the simplest way to commit that to a branch. Reading bzr doc, I have the impression that I need to download a fresh branch wit "bzr branch lp:yade". Can't I do that directly with my local version? -- You received this bug notification because you are a member of Yade developers, which is the registrant for Yade. https://bugs.launchpad.net/bugs/729079 Title: Performance optimization of InsertionSortCollider Status in Yet Another Dynamic Engine: New Bug description: Sergei Dorofeenko (https://launchpad.net/~sergei.dorofeenko) found, that InsertionSortCollider is probably is a "bottle neck" in simulations with >10^5 number of particles even in many-threads mode. http://www.mail-archive.com/[email protected]/msg06573.html Сitation: "...I did a perfomance test for parallel mode and results in no good. Performance boost only about 40% from 1 thread to 4 thread for 200k particles... Cause is a non-parallelised InsertionSortCollider, who need about 80% time with 4 threads. Results attached." _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
