I could see how a low-latency interconnect would help with a
Second Life-like virtual reality, where most things happen
server-side. On the other hand, given that low-end servers
come with 4 GBit Ethernet NICs, just distributing the game
world across a 2d torus would do as well, or better.
Has anyone ever heard of a cluster wired in a diamond
lattice (made from tetrahedrons) topology?
I haven't heard of anyone using a diamond lattice to wire a cluster. We're
using a Kautz graph, which already makes my brain hurt.
What would the advantages of a diamond lattice be? In terms of
bisection and diameter?
Ease of wiring?
