[rescue] New Origin 3400 in Ottawa

[Lionel Peterson]

Patrick,

I don't follow... this machine has 5x 4 processor 'boxes' that are all
NUMA-attached, presenting a single, large, 20 CPU box with 10 gigs of RAM.

How is that different from, say, a modern dual sixteen-core machine with a
similar amount of RAM? It presents as one big system with one OS image
managing all resources.

The difference I see is you can add more 'blocks' to expand the system,
increasing the system image easily.
