IIRC ROCm (in the form of HIP) defines a new C/C++ API that maps to either AMD intrincis or CUDA depending on a compile time flag.
It required converting your CUDA source code to ROCm code, though there was a code translation tool to help you with that.
To be honest: I don't really understand what ROCm stands for. AMD has been redefining their GP compute platforms so many times that it's easy to lose track.
Yeah I’m sure stuff like this can work without code rewrite but my guess is that it’s far from plug and play. I couldn’t use that to run my model on an AMD card tommorrow without some effort.
