felix_eugene Posted August 12, 2016 Share Posted August 12, 2016 Hi guys, I got some problem here. I'm using houdini FX 15.5 My spec: DUAL xeon e5-2698v4. 40 core/80 threads RAM 64GB ECC The problem is when I do caching or Mantra Rendering, Houdini only using 40 threads, means half of the total threads available. I suspect that Houdini does not using any of the core in the Second Xeon CPU. This is very sad, do you guys know what causing this? any solution perhaps? Thanks in advance Quote Link to comment Share on other sites More sharing options...

Guest tar Posted August 14, 2016 Share Posted August 14, 2016 I think you can install Houdini on the boot USB of Unbuntu to test. It should work with all procs anyways but haven't tested. Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted August 15, 2016 Share Posted August 15, 2016 (edited) What version of Windows are you using? EDIT: Never mind. Holy crap, why does Windows do that?

I tried to use Ubuntu 16 but it only shows 59 cores instead of 80 cores and Linux is too hard for me too use Quote Link to comment Share on other sites More sharing options...

The home versions are limited to a single processor socket. While it still might be limited to 64 logical cores that's better than 40 logical cores.

The same thing happened with Renderman and Mantra. Also Renderman in Maya too Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted August 15, 2016 Share Posted August 15, 2016 Looks like the bug in Ubuntu is just a reporting bug. Have you tried actually rendering something in Ubuntu? https://bugs.launchpad.net/gnome-control-center/+bug/1545955 Quote Link to comment Share on other sites More sharing options...

I have never installing a program using a terminal and I'm lost completely.... So I think I will just stick windows and turn off the Hyperthreading. I got a clock speed improvement from 1.5 GHz to 2.2 Ghz, not bad but I lose the core amount if Houdini use the second processor group. Oh I also noticed that cooking in houdini is very slow? Is that because all cooking operation even in DOP or VOP are singlethreaded? Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted August 15, 2016 Share Posted August 15, 2016 Some tasks in Houdini use a single thread. Change the power settings in Windows to not throttle. Ever. If you decide to try Linux again it's pretty straightforward to install Houdini. I cover it in a video on cmiVFX (shameless self plug). https://cmivfx.com/store/480-Linux+For+VFX+And+CG+Production+Environments Quote Link to comment Share on other sites More sharing options...
