An 18-node visualization cluster provides the rendering backbone for the Reality Deck facility. Each node features dual Intel Xeon CPUs, each with 6 cores, as well as 48 GB of RAM and 1 TB of local storage. The nodes are interconnected over Infiniband and Gigabit Ethernet.
Every machine contains 4 AMD Firepro V9800 GPUs that can drive up to 6 monitors at their native resolution. Effectively, each cluster node can drive up to 24 monitors for almost 90 megapixels of visual space.
