The company's challenge was to build a cluster appropriate for applications such as climate modeling, ray tracing, and visualization. Reduce the overhead cost stemming from the two-network architecture (LAN and cluster fabric), but accomplish high throughput at low latency. The CAFfeine (for Chelsio, AMD, Fujitsu) cluster links (8) Celestica Quartet A8440 servers (each with four AMD Opterons) with 10 Gigabit Ethernet for both LAN and cluster fabric using Fujitsu XG-800 switches and (8) Chelsio T110 Protocol Engines as network adapters.
