Hi Andy, I've just checked and Smooth 2.0 is definitely running on the CPU. I just ran it at a ridiculously high strength (iterations) of 10,000 so I had time to monitor the CPU and all 32 threads on my workstation run at full kilter. I also checked my GPU load via GPU-Z and none of my (3) GPU's had any load. I remember someone posting an OpenCL smooth implementation last year - https://vimeo.com/172167812 - but I don't think it's connected to anything SideFX have done in H16.
The docs mention the Attribute Blur Sop running via OpenCL on the GPU and there's an all inclusive, non specific statement of extensive OpenCL support in SOP's but SideFX aren't being committal as where they've implemented it. Anyway, the important bit is that Smooth 2.0 is massively improved on previous versions. It's also quite interesting running the new Smooth at crazy high iterations for more abstract effects. ;) On 28 February 2017 at 19:06, Andy Goehler <[email protected]> wrote: > IIRC, the new Smooth 2.0 and Attribute Blur SOPs even use OpenCL.
