If only CPU is it Multithreaded

The authors offer CPU and CUDA implementations.
We are only using the CPU version.
It is multithreaded.

Thanks for the info.

Well, 20secs for an image... when the alternative (no denoiser) is to wait minutes or hours to have the same "noisefree" level... is this real a problem?

I know it is faster. What I want to know was, if it is implemented in OpenCL.

As BYOB mentioned it is CPU multithreaded. If it was in OpenCL(may be in future) it would be much faster (may be 5 secs) .

Have a question, blender denoise removes fireflies. How is handling fireflies this denoise function?

Thanks

We have variance clamping for that task

Of course! But In the case of cycles, this seems to be a happy side effect. I was just asking what happens to fireflies, in case it appears one when not using variance clamping properly (or not so accurately).

They are usually smoothed but not removed.

Did I ever said how damn well this thing works ?
A 10 mins rendering, it makes animations possible.

yes..it's working good.

I'm impatient to test it in my test scene...

Let's first test how bad the flickering will be.
