<br>
I think the answer to the question lies here:<br>
<br>
<a href="https://en.wikipedia.org/wiki/OpenACC"
rel="noreferrer" target="_blank" moz-do-not-send="true">https://en.wikipedia.org/wiki/OpenACC</a><br>
<br>
As I follow these things rather loosely, my understanding
was that OpenACC <br>
should run on both nVidia and other GPUs. So maybe that is
the reason why it <br>
is a 'pure' AMD cluster where both GPUs and CPUs are from
the same supplier?<br>
IF all of that is working out and if it is really true that
you can compile <br>
and run OpenACC code on both types of GPUs, it would a be
big win for AMD.<br>
<br>
Time will tell!<br>
<br>
All the best from my TARDIS!<br>

Competition and vendor lock-in. <br>
