Dear all,
I think the answer to the question lies here:
https://en.wikipedia.org/wiki/OpenACC
As I follow these things rather loosely, my understanding was that
OpenACC
should run on both nVidia and other GPUs. So maybe that is the
reason why it
is a 'pure' AMD cluster where both GPUs and CPUs are from the same
supplier?
IF all of that is working out and if it is really true that you
can compile
and run OpenACC code on both types of GPUs, it would a be big win
for AMD.
Time will tell!
All the best from my TARDIS!

Once upon a time portability, interoperabiilty, standardization, were
considered good software and hardware attributes.
Whatever happened to them?
Competition and vendor lock-in.
