oneAPI for AMD GPUs and ROCM 5.x

Hello!

It appears that the PI plugin for AMD GPUs is linked against ROCm 4.x:

Is there a version of the HIP PI plugin linked against ROCm 5.x? ROCm 5.0 was released in February, so one might expect the 5.x branch to be relatively popular already.

(building from source is an option, of course, but that’s not very user-friendly)

Thanks for the post. We’ve had a think about this since as you say at the moment we build against ROCm v4.
We’re thinking about how we can support multiple versions in the future but in the meantime your options are to compile from source (as you also suggested) or to install v4 alongside v5 and link against v4.

There are instructions on how to install multiple ROCm versions here in case that helps.
