Cerebras CS-3 Inference Cluster (8-node)
An eight-node Cerebras inference cluster, where a node is one CS-3 system. Cerebras provisions it as five cabinets: four WSE cabinets holding two CS-3 systems each, plus one NET cabinet. Provisioned heat load is approximately 240 kW, of which about 220 kW is carried by water and 20 kW by air. Note that this is Cerebras's own provisioned figure and is higher than eight times the 27 kW system power, because it includes the networking cabinet. The cluster holds 352 GB of on-chip SRAM and no DRAM. Cerebras rates each engine at 125 petaFLOPS but footnotes the figure as sparse, and because the sparsity is unstructured no dense equivalent is derived.
