[Beowulf] An Epyc move for Cray

[Christopher Samuel]

For those who haven't seen, Cray has announced their new Shasta
architecture for forthcoming systems like NERSC-9 (the replacement for
Edison).

It's interesting as Cray have jumped back to using AMD CPUs (Epyc)
alongside nVidia GPUs, in conjunction with a new interconnect (Slingshot).

I've got to say that the name of the new NERSC system reminds me of
people struggling to program in a particular scripting language.. ;-)

Now I've seen the Cray PR it seems it might not be as closely coupled as
it initially reads..

# With Shasta you can mix and match processor architectures (X86, Arm®,
# GPUs) in the same system as well as system interconnects from Cray
# (Slingshot™), Intel (Omni-Path) or Mellanox (InfiniBand®).
