larmannjan Posted June 30, 2013 Share 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 Posted July 1, 2013 Share 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. Quote Link to comment Share on other sites More sharing options...
sanostol Posted July 1, 2013 Share 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 Quote Link to comment Share on other sites More sharing options...
larmannjan Posted July 1, 2013 Author Share Posted July 1, 2013 try to rebuild all pop nodes with vopPops they are multihreaded, thanks, I just started houdini and am not sure what you really mean but I will keep an eye out for it Quote Link to comment Share on other sites More sharing options...
larmannjan Posted July 1, 2013 Author Share 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 Quote Link to comment Share on other sites More sharing options...
cubiccube Posted July 2, 2013 Share Posted July 2, 2013 On the DOP network node there's a "reset simulation" button, plus other controls for caching. Quote Link to comment Share on other sites More sharing options...
