larmannjan 0 Posted June 30, 2013 I am simulating a lot of particles. Why is Houdini not using all threads to the full extent. Is this normal, is this as much multi-threading as I can get out of houdini. I have 4 real threads and its not even using one of them fully (which would be 25%). Just wondering.

Erik_JE 38 Posted July 1, 2013 A lot of the POP nodes ain't multi-threaded so without using a different approach you won't be getting more usage. Share this post Link to post Share on other sites
sanostol 75 Posted July 1, 2013 (edited) try to rebuild all pop nodes with vopPops they are multihreaded, there are still some nodes that You can't really avoid by that way, but it speeds up things EDIT: in 12.5 many vexfunctions where improved and have better threading. for example the intersect, primattrib and xyzdistance are very fast now. it might be a bit more work at the beginning Edited July 1, 2013 by sanostol 1 Share this post Link to post Share on other sites

larmannjan 0 Posted July 1, 2013 How do I purge the ram in houdini. I was doing some Rigid body sims and let it play over and over again always trying out new stuff but my ram is kinda getting full? How do i purge ram without restarting? thanks Share this post Link to post Share on other sites
cubiccube 12 Posted July 2, 2013 On the DOP network node there's a "reset simulation" button, plus other controls for caching. Share this post Link to post Share on other sites
