[rescue] New Origin 3400 in Ottawa

[Patrick Giagnocavo]

The Origin is not welded-together as a black box, I guess.  If you get a dual-CPU system, it goes on one motherboard, with one group of RAM slots - everything is integrated.

Even if you take a dual sixteen-core machine, and put 40Gbps Infiniband on it between it and another one, you just have ... 2 systems.  You can't get single-system image out of Solaris nor Linux with such a setup.

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.
