Context Before

This is why the belly-to-belly layout is used: it reduces the ‘X’ and

Evidence

‘Y’ distance between all the LPUs and instead have routing go in the ‘Z’ dimension.

Context After

The LPU also has 1x100G going to one FPGA, with each FPGA interfacing with 8 LPUs. The 2 FPGAs each have 8x PCIe Gen 5 going to the CPUs. The LPU needs to traverse through the FPGA to interface with the CPU as LPUs don’t have PCIe PHYs to interface directly.

② Atomic Claim

……所有 LPU 之間的 Y 距離，並改讓 routing 走 Z 維度。
