Hello, I’m trying to use CUDA (more specifically, the NVIDIA video codec SDK [url] https://developer.nvidia.com/nvidia-video-codec-sdk[/url] ) with D3D12 in an existing application using DirectX 12. Since there’s no cuD3D12CtxCreate (yet?), I though that I could just use D3D11On12 to get a ID3D11Dev…

At the risk of just bumping an old thread, but is there any update on this? Is it possible to use d3d11on12 interop with the nvidia decoder? Or perhaps directly interface with D3D12? APIs like cudaGraphicsD3D12RegisterResource are still(?) not there as you would have on D3D11, e.g.: cudaGraphicsD…

Did you checked out the cuda sample simpleD3D12 ? There is a buffer (a set of vertex) sharing between D3D12 and cuda, and it works very well. I’m trying to make the interop work not with buffers but with texture2D (D3D12) and one of {Tex2D, surface2D, 2D array} in cuda. I don’t think it’s a good i…

Hello guys, im stuck at the same point, i need cudaGraphicsD3D12RegisterResource but it looks still not available. have you ever found the equivalent for DirectX12? Thanks.

hi @Steerlock , I’m also stuck at where you have been. Have found the proper way to register a d3d12 texture to cuda eventually?

I’m not a D3D expert. My suggestion would be to look at the simpleD3D12 sample code and use that as the modern method for interop. Yes, I acknowledge it does not directly show how to share a texture. The “other way” could be to share another kind of buffer object, using the “modern” interop based…

Thank you. By “modern” do you mean cudaImportExternalMemory is prefered, while cudaGraphics interop is outdated and should be replaced?

I mean cudaImportExternalMemory was introduced much more recently in the CUDA lifecycle than the “traditional” methods such as cudaGraphicsD3D...

CUDA interop with D3D12 possible?

hi @Robert_Crovella ,
Could you please give us some pointers? I need to register and map D3D12 texture to cuda, just like the simpleD3D11Texture demo from the official sample. But since there’s no cudaGraphicsD3D12RegisterResource API, there must be some other way?
