Context Before
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
Evidence
given the dense all-to-all mesh for intra-node connections this requires a very high spec PCB to support the routing.
Context After
The belly-to-belly mounting is used to reduce PCB trace lengths across the ‘X’ and ‘Y’ dimensions.
② Atomic Claim
由於 intra-node connection 採 dense all-to-all mesh，需要非常高規格的 PCB 才能支援 routing。
