Rendering Pyro directly on the GPU is not working at the moment, it's a limitation. You can cache the simulation and load the VDB volume with the Arnold Volume object. That can be rendered on the GPU.

To be able to render in the IPR, you have to set the channels in the Pyro object to On, as discussed in this thread: https://forums.autodesk.com/t5/arnold-for-cinema-4d-forum/new-pyro-tag-in-c4d-arnold-how-to-actually...
