Re: [802.3BA] XR ad hoc Phone Conference Notice

What is a supercomputer?
Used to be a huge custom box (sometimes several) that needed
a nuclear power station nearby. Today, it is a collection of
a lot (thousands to 10s of thousands) of tiny compute nodes,
COS, using very fast low-latency interconnects.

What is a traditional commercial datacenter?
Same as above, only on a much smaller scale (hundreds to may
be a few thousand nodes).

My point is that from a datacenter architecture and deployment
model, the two are one and the same. If 100m is enough to build
a supercomputer, it is enough to build any commercial system.
It comes down to the size of the datacenter where either one
of them is deployed. At least from our customer base, what we
hear is that links above 100m are very uncommon.

this is a revelation to me. If I understand your brief response, you are claiming that the direction of future data center design will be based around a super computer. I find that very interesting. But it does little to address all of the more traditional data centers which are not centered around super computers and have channel lengths exceeding 100m. Your position for all of those is to deploy a 10km SM solution for anything longer than 100m. To me that is a recipe for stalled market penetration that will last for much longer than the delay we observed at 10G.
