anupamd Posted October 1, 2014 Share Posted October 1, 2014 I know to some extent this has been discussed on other threads but its not clear to me. To what extent does Flip , Pyro, and RBD use multi-core processors? Is it necessary to tweak any settings to optimize for multi-core machines. If so is there any documentation available for this? I am currently building a dual 6 core intel I5 and want to make sure im not wasting money on the dual proc if houdini is not even going to utilize the multi cores.

Solitude Posted October 1, 2014 Share Posted October 1, 2014 Bullet (for rbds) doesn't use multi-core very much by default, but it does have a multithreaded option, at the cost of disabling a few features. Flip, and Pyro utilize all the cores very well. Flip has one option "use preconditioner" which is on by default, but should probably be turned off for your machine. http://www.sidefx.com/docs/houdini13.0/nodes/dop/flipsolver#idm47059886392016 Quote Link to comment Share on other sites More sharing options...
anupamd Posted October 1, 2014 Author Share Posted October 1, 2014 Thanks for the info Ian. Another quick question. I have the option of utilizing a dual 6core 2.6ghz or a dual 4 core 3.5ghz. Not sure which to get as im unclear as to if the number of cores will win over raw horsepower per processor. Any opinions on the matter would be helpful. - Anupam Quote Link to comment Share on other sites More sharing options...
Solitude Posted October 2, 2014 Share Posted October 2, 2014 No idea... you'll want to look at multithreading benchmarks between the two. Quote Link to comment Share on other sites More sharing options...
