Does anyone have the link for downloading the Ubuntu 16.10 AMD Ryzen OpenCL CPU drivers? OpenCL CPU is working out of the box but the Frequency is looking a little suspicious

Cool - so put into the environment file HOUDINI_OCL_DEVICETYPE=CPU, check that it used in the Help menu, About Houdini, scroll down for the openCL part. You can also just use the hgpuinfo -c command in the terminal / command line instead.
then hunt down the OpenCL Smoke example file from the help docs and boost the number of voxels to something like 600x600x600 for axis, you can also just build a simple smoke sim where you just source for the first few frames or for fun you can now source on all frames and compare the CPU to the GPU as it doesn't have to send the data across PCI
Pyro is also now fully openCL so use the shelf tools there, make sure to switch on use OpenCL, then the Sand tools, just use the shelf etc.
Overall the 1950X will be great for all the threaded nodes in Houdini, like VDB, OpenCLSOP, Attribute Blur and of course Mantra.
Viscoisty in Flip sims is very well OpenCL'd in my experience too.
Keen to hear your results!
