Evidence
The LPU modules are mounted in a belly-to-belly on the PCB, meaning 8 LP30 modules on the top side of the PCB and the other 8 LP30 modules on the bottom. All of the connectivity that comes out of the LPU are via PCB traces and given the dense all-to-all mesh for intra-node connections this requires a very high spec PCB to support the routing. The belly-to-belly mounting is used to reduce PCB trace lengths across the ‘X’ and ‘Y’ dimensions.
