Parallel Computing Infrastructure

The Collaboratory for Advanced Computing and Simulations (CACS) of Drs. Kalia, Nakano, and Vashishta consists of a parallel computing laboratory in the Department of Physics and Astronomy. These labs have:

  1. A 166-node Pentium III cluster (800/850 MHz) on a hierarchical fabric of Gigabit and fast Ethernet switches.
  2. A 256 processor Intel Xeon cluster on Myrinet is being purchased and is expected to be operational by Summer 2003.

The University of Southern California has an extensive high performance computing facility made up of several multi-processor computers. These include:

  1. A 64 processor SUN Sunfire 15K system.
  2. A 576 dual processor IBM Linux cluster comprising of Pentium III (766Mhz, 866Mhz & 1.2Ghz) and Xeon processors (2.0Ghz).

Collaboration and Visualization Facilities

The virtual environment laboratory houses a multi-user, immersive and interactive ImmersaDeskR2, a number of SGI multiprocessor servers and workstations, and stereographic equipment. The ImmersaDeskR2 system provides interactive, stereoscopic data projection. The system includes a large, high-resolution, pivotal screen, head tracking system; eyewear kit; IR emitters; wand with a tracking sensor; and wand tracking I/O subsystem. Users are able to view, interact, and immerse themselves in the computer imagery projected on the screen.

In addition to this an Access grid collaboratorium has been constructed. It consists of a dedicated space with immersive audio and visualization capabilities that remotely supports tutorials, lectures, meetings, conferences, and all other forms of interactions that currently require face-to-face meetings. The collaboratorium has a large, high-resolution projection wall (18' by 12') and seating area of about 25' wide and 20' deep. Imagery on the wall is projected with ceiling-mounted projectors of sufficient brightness so that the room can operate in normal light for people to read and interact. The room has a full duplex, hands-free audio system to converse with other groups, a display computer to manage tiled display and decode video streams from other groups, a video capture computer with 4 video cards, an audio capture computer for audio coding and broadcasting, and a control computer to run software for audio gear.
