Context Before

Something interesting about the system is the important role the FPGAs play. Nvidia refers to the FPGAs as “Fabric Expansion Logic” which serves multiple purposes. First, they act as a NIC which converts the LPU’s C2C protocol into Ethernet to connect to the Spectrum-X based ethernet scale-out fabric.

Evidence

It is this scale-out fabric through which the LPUs connect to GPUs in the decode system.

Context After

Second, the LPUs also traverse through the FPGAs to reach the host CPU, with the FPGAs converting C2C to PCIe to the CPU.

② Atomic Claim

LPU 就是透過這個 scale-out fabric，在 decode system 中連接到 GPU。
