Configuration Summary

Jade contains 2,146 compute nodes (8,584 compute cores). Each compute node contains a 2.1‑GHz AMD Opteron 64‑bit quad‑core processor and 8 GBytes of dedicated memory. The nodes are connected to each other in a three‑dimensional torus using a HyperTransport link to a dedicated Cray SeaStar2 communications engine that provides high‑bandwidth, high‑performance interconnects. Jade has 379 TBytes of Fibre Channel RAID disk storage and a peak performance of 72.3 TFLOPS.
