  In the era of Big Data, with the increasing use of large-scale data-driven
applications, the visualization of very large high-resolution images and
extracting useful information (searching for specific targets or rare signal
events) from these images can pose challenges to the current video-wall display
technologies. At Bellarmine University, we have set up an Advanced
Visualization and Computational Lab (AVCL) using a state-of-the-art next
generation video-wall technology, called Hiperwall (Highly Interactive
Parallelized Display Wall). The 16 feet wide by 4.5 feet high Hiperwall
visualization system consists of eight display tiles that are arranged in a 4x2
tile format and has an effective resolution of 16.5 Megapixels. Using
Hiperwall, we can perform interactive visual data analytics of large images by
conducting comparative views of multiple large images in Astronomy and multiple
data events in experimental High Energy Physics (HEP). Users can display a
single large image across all the display tiles, or view many different images
simultaneously on multiple display tiles. Hiperwall enables simultaneous
visualization of multiple high resolution images and its contents on the entire
display wall without loss of clarity. Hiperwall's middleware also allows
researchers in geographically diverse locations to collaborate on large
scientific experiments. In this paper we will provide a description of a new
generation of display wall setup at Bellarmine University that is based on the
Hiperwall technology, which is a robust visualization system for Big Data
research.
