Hi Davide, Then this is asking whether you can run CUDA code on AMD GPUs. While tools like *Heterogeneous-compute Interface for Portability* might offer porting CUDA code to HIP code for AMD GPUs to run, you probably see more failures than successes. For DEME, the chance that it works is even slimmer since it uses NIVIDA jitify. So I'd say no, unless you are super hacky and ready to legitimately become a developer of DEME by contributing to it.
