The SGI Onyx 3400
The work horse of the visualization system at IGPP is an SGI Onyx 3400 graphics supercomputer, powered by 16 MIPS processors (64-bit R1200, 400 MHz) with 16 GB of addressable memory. Graphics are rendered using SGI's advanced Infinite Reality 3 Graphics system, using 4 graphics engines (single pipe) and two raster managers with 512MB of texture memory. The disk storage subsystem is a JBOD fiber connected, stripped disk farm, containing 400 GB of disk space (expanding to 1.5 TB soon) with access rates of up to 125MB/sec. A flat-screen, 24" Sony Trinitron monitor permits local visualization and system management.
The immersive visualization theatre is located in the Revelle Conference Room at IGPP, which is home to a custom install of Panoram Techonologies' GVR 120E conference center. This virtual reality environment uses 3 channels of video that spans a 21' by 8. cylindrical hard screen This virtual reality environment uses 3 channels of video that spans a 21' by 8' cylindrical hard screen, enabling 3.2+ million pixels of information, slightly less in stereo modes. Video Panoram edge blending presents a seamless image across the 3 input video channels. The Integrator 3 provides total control of video and audio inputs from the Onyx ( mono and stereo modes ), S-VHS Player, DVD Player and Mac/PC. The audio system is a six channel surround sound system with LR front, LR rear, center and subwoofer.
Video and analog signals are transported 220 meters via Lightwave Communication's VDE/200 Video Display Extension Kit . Nine channels of video and analog devices [ including keyboard, mouse, stereo emitter, serial output, ADAT sound ] are transported optically via fiber from IGPP Building 2000 to the Revelle Conference Room without signal degradation.
