    I'm baffled ;-)
    Why does a machine of this class have an FPA option. I would think it should be standard
    equipment.                                   ^^^^^^

It's already pretty fast without it.  You'd have to be pretty desperate
to need to accelerate it even more.

    I'm even more baffled by how you configure 125 nodes as a hypercube.

Sounds like a four-dimensional hyper-pentagonal-prism, with five nodes
along each edge.
