I think the only practical use of this possibility might have been in
the HPC space. I don't know anybody running such a system, though.
In-memory databases also benefit from really large systems. Lots of RAM
requires lots of sockets, which bring along lots of cores. Eg.

I believe KVM will let you define a VM with > 64 CPUs, and recent
versions provide some control over the NUMA layout of the virtual
sockets/cores/threads. Maybe that will give you what you're looking
for, Corinna.
