The distributed ASCI supercomputer project

The Distributed ASCI Supercomputer (DAS) is a homogeneous wide-area distributed system consisting of four cluster computers at different locations. DAS has been used for research on communication software, parallel languages and programming systems, schedulers, parallel applications, and distributed applications. The paper gives a preview of the most interesting research results obtained so far in the DAS project

Enabling Tiled Displays for Education

This document describes the interaction with the ICWall tiled display built at the Vrije Universiteit, within a project called MultiVLA. The display has been setup within an educational environment and is used for several lectures from computer science (graphics, parallel programming, AI), physics, and chemistry. We describe a system consisting of several free software components that allows novice users to display their multimedia onto the tiled display. The user interface is simple and requires no knowledge about the underlying architecture, hiding the complex parallel rendering system driving the display. Since the wall is also used for research, the system allows for flexible switching between desktop applications and virtual reality application

Griz: experience with remote visualization over an optical grid

This paper describes the experiments of remote rendering over an intercontinental optical network during the iGrid2002 conference in Amsterdam from September 23 to 26. A rendering cluster in Chicago was used to generate images which were displayed in real-time on a 4-tile visualization setup in Amsterdam. On average, one gigabit per second (1Gbps) was consumed to enable remote visualization, at interactive frame rate, with a 1600 × 1200 pixels configuration. © 2003 Elsevier B.V. All rights reserved

Measuring in Virtual Reality: A Case Study in Dentistry

For application specialists to accept virtual reality (VR) as a valid new measuring environment, we conducted several case studies. This paper describes a case study in dentistry in which VR is used to measure the length of the root canal of a tooth from processed tomography data. This paper shows the advantages of measuring in visualization space rather than in reality.We present a software framework aimed at the application specialist rather than the VR expert. Furthermore, the VR measuring technique is analyzed and compared to traditional measuring techniques for this particular application. We show that VR allows for intuitive measuring paradigms that are accurate and versatile alternatives to situations where traditional techniques are deficient. © 2008 IEEE
