I am thinking of building a new workstation with 2 GPU's for compute purposes (FP64 >= 1/4 FP32). The main ways I am thinking of using this heterogeneous compute workstation is :

- Use the two GPUs separately for compute loads by programming Cpu+AMD card using OpenCL and CPU+NVIDIA card using CUDA
- Use the two cards together with CPU for compute loads by using AMDs new portable HIP API infrastructure.

Does anyone know if AMD and NVIDIA GPUs can be used in the above two usage ways ?
 
Solution
No the difference in drivers would conflict one another. There maybe some hack crap work around but i would not trust anything like that. You would have to run one or the other. (nvidia or amd)

I don't think you can put two different cards into one machine. I know you can do it through some sort of hack or something but I wouldn't say it would be the most reliable thing in the world.
