loogas Posted March 13, 2017 Share Posted March 13, 2017 (edited) Thank you for pointing that out edward My bad. However, I've installed it and it's still the same - no OpenCL device :/ And sorry that I'm posting about Windows in the Linux-related topic but the common thing is the Nvidia/OpenCL problem. I'll check Linux and we'll see. Edited March 13, 2017 by loogas grammar Quote Link to comment Share on other sites More sharing options...
Atom Posted March 13, 2017 Share Posted March 13, 2017 But isn't the 580GTX below the required hardware spec of 2GB of vRam? You may just need a better graphics card to run Houdini. Quote Link to comment Share on other sites More sharing options...
Guest tar Posted March 13, 2017 Share Posted March 13, 2017 (edited) @loogas has an AMD processor and again the built-in OpenCL CPU doesn't work. Kind of confirms that AMD CPU OpenCL isn't supported out of the box. This affects features such as the terrain tools as it appears that OpenCL 1.2 is an absolutely requirement as there isn't C++ fallbacks, yet. Maybe the manual should have how to install AMD CPU OpenCL. The 580GTX doesn't appear to support OpenCL 1.2, only 1.1, which is required for H16.

loogas Posted March 13, 2017 Share Posted March 13, 2017 @Atommy GTX580 has 3GB of memory but good guess @martyI was wondering if the version is the problem (platform version vs. device version in my screenshots). It seems it is. Well, I've installed Linux Mint just to check this issue there and I can confirm that OpenCL support on my GTX580 doesn't work in Houdini 16 Apprentice on Linux as well. Time to upgrade then (I think I can borrow a different card ;)). Thanks for your input guys. Quote Link to comment Share on other sites More sharing options...
Guest tar Posted March 13, 2017 Share Posted March 13, 2017 yeah - the software driver version capabilities will be different to hardware capabilities. Until the new card arrives try the AMD OpenCL CPU driver, below, and set the env var HOUDINI_OCL_DEVICETYPE='CPU'. You should be able to use the CPU as the OpenCL device. http://support.amd.com/en-us/kb-articles/Pages/OpenCL2-Driver.aspx Quote Link to comment Share on other sites More sharing options...
