IHPC established the second tiled display wall in 2006, which is composed of 2x3 high-resolution three-chip Digital Light Processing (DLP) projectors and a Linux HP SVA cluster (6 display nodes, 2 rendering nodes and 2 head node). Compared with our 1st generation 2x2 tile display and CAVE™ (CAVE Automatic Virtual Environment), it has a higher resolution, sharper and bigger overall viewing frontage of 215” diagonally with a combined display resolution of 8.82Mpixels. Like its CAVE™ predecessor, it is also capable of providing users with higher-resolution stereoscopic viewing through the help of the special goggles.
The visualization application is launched on a Linux platform through an Application Master Node and the display workload is then distributed across the 6 display nodes. Each node comprises two AMD Opteron processors, 16GB memory and Nvidia Quadro FX4500 graphics card. All the nodes are inter-connected through a dedicated Infiniband network infrastructure capable of moving data at 10 Gbits/s in addition to the Gigabit network infrastructure.


3D Graphics API Toolkit @ 2x3 tile display

Below are the updated lists of applications and API toolkits installed on the Linux Cluster that support the 2x3 tile display.

SGI OpenGL Performer - Version 3.2.4

OpenGL Performer™ is a toolkit for developers creating real-time applications used for virtual reality, visual simulation, scientific visualization, simulation-based design, architectural walk-through, and etc.

OpenSG - Version 1.6

OpenSG is a scene graph system to create OpenGL-based realtime graphics programs. It is developed following Open Source principles, LGPL licensed, and can be used freely. Its main features are advanced multithreading and clustering support (with sort-first and sort-last rendering, amongst other techniques).

OpenSceneGraph - Version 1.2

The OpenSceneGraph is an open source high performance 3D graphics toolkit, used by application developers in fields such as visual simulation, computer games, virtual reality, scientific visualization and modelling.

OpenInventor (Trial) - Version 6.1

Open Inventor™ is an object-oriented 3D toolkit offering a solution to interactive graphics programming problems. It presents a programming model based on a 3D scene database that dramatically simplifies graphics programming.

3D Application

Paraview (Stereoscopic viewing Enabled) - Version 2.4.4

ParaView is an open source program for scientific visualization. It has a client-server architecture to facilitate remote visualization of datasets which is based on Visualization Tool Kit (VTK) libraries.

VisIT (Stereoscopic viewing Enabled) - Version 1.11.1

VisIt is a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. VisIt was designed to handle very large data set sizes in the terascale range and yet can also handle small data sets in the kilobyte range.

VMD (Stereoscopic viewing Enabled) - Version 1.8.5 / 1.8.4

VMD a visualization and analysis application of biological systems such as proteins, nucleic acids, lipid bilayer assemblies, etc. It may be used to view more general molecules, as VMD can read standard Protein Data Bank (PDB) files and display the contained structure. VMD can be used to animate and analyze the trajectory of a molecular dynamics (MD) simulation. In particular, VMD can act as a graphical front end for an external MD program by displaying and animating a molecule undergoing simulation on a remote computer.
  • NAMD is installed and configured on the cluster.

IGV (Integrative Genomics Viewer) - Version 1.1

Integrative Genomics Viewer is a fast, flexible viewer for genomic data. IGV visually integrates datasets from various platforms and sources.

Guess - Version 1.0.2

GUESS is an exploratory data analysis and visualization tool for graphs and networks. The system contains a domain-specific embedded language called Gython (an extension of Python, or more specifically Jython) which supports the operators and syntactic sugar necessary for working on graph structures in an intuitive manner.

Walrus - Version 0.6.3

Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. By employing a fisheye-like distortion, it provides a display that simultaneously shows local detail and the global context.
