    ABSTRACT: Virtual reality (VR) has long been hampered by the gear needed to make the experience possible; specifically, stereo glasses and tracking devices. Autostereoscopic display devices are gaining popularity by freeing the user from stereo glasses, however few qualify as VR displays. The Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC) has designed and produced a large scale, high resolution head-tracked barrier-strip autostereoscopic display system that produces a VR immersive experience without requiring the user to wear any encumbrances. The resulting system, called Varrier, is a passive parallax barrier 35-panel tiled display that produces a wide field of view, head-tracked VR experience. This paper presents background material related to parallax barrier autostereoscopy, provides system configuration and construction details, examines Varrier interleaving algorithms used to produce the stereo images, introduces calibration and testing, and discusses the camera-based tracking subsystem.

    ABSTRACT: High-performance computing clusters (commodity hardware with low-latency, high-bandwidth interconnects) based on Linux, are rapidly becoming the dominant computing platform for a wide range of scientific disciplines.Yet, straightforward software installation, maintenance, and health monitoring for large-scale clusters has been a consistent and nagging problem for non-cluster experts.The NPACI Rocks toolkit takes a fresh perspective on management and installation of clusters to dramatically simplify software version tracking, and cluster integration.The toolkit incorporates the latest Red Hat distribution (including security patches) with additional cluster-specific software.Using the identical software tools used to create the base distribution, users can customize and localize Rocks for their site.Strong adherence to widely-used (\emph{de facto}) tools allows Rocks to move with the rapid pace of Linux development.Version 2.1 of the toolkit is available for download and installation.To date, 10 clusters spread among 5 institutions have been built using this toolkit.
