Context Before

Evidence

The LPU network can be divided into the scale-up ‘C2C’ network

Context After

and scale-out network which interacts with the Nvidia GPUs through Spectrum-X. First let’s discuss the scale-up network which can be divided into 3 portions: intra-node, inter-node/intra-rack, inter-rack. For C2C within the rack Nvidia announced a total of 640TB/s of scale up bandwidth per rack which comes from 256 LPUs x 90 lanes x 112Gbps/8 x 2 directions = 645TB/s.

② Atomic Claim

LPU network 可以分成 scale-up 的 C2C network。
