[Beowulf] AMD and AVX512 [EXT]

[John Hearns]

That is a very interesting point! I never thought of that.
Also mobile drives ARM development - yes I know the CPUs in Isambard and
Fugaku will not be seen in your mobile phone but the ecosystem is propped
up by having a diverse market and also the power saving priorities of
mobile will influence HPC ARM CPUs.
