I'm wondering the same. I'd guess that 99% of science code that uses the GPU now depends on CUDA. The other 1% use other third-party GPU frontends which might also be tuned for Nvidia GPUs. I feel that it's good to use the AMD ecosystem to mix up the competition a bit, and the majority of other clusters will still use Nvidia if your application requires it, but I'm just not aware of any momentum at all (in the form of software ecosystems) that target AMD, so library-writers will have to basically start from scratch if this AMD cluster is confirmed.
