High Resolution Tiled Display Wall & Linux Cluster


The LionEyes Display Wall is a rear-projected high-resolution display powerwall and graphics cluster with a configuration of 4x3 tiles of 1024x768 resolution projectors, for a total of almost ten million pixels. Each tile is driven by a dual-processor render node. Twelve render nodes are controlled by two application nodes for a total of 28 processors.

The high-resolution and large display size allow for the researcher to see the entire scope and context of a problem but still see minute detail. Scaling is key to recognition of patterns within data. Instead of looking through a pin-hole on a desktop computer, the display wall offers a complete mural of information. Another mode that is useful is viewing many time-steps or slices side-by-side. Large spread-sheets, matrices and simple text such as genome code can also be analyzed with increased clarity and insight.
