product overview
Chapter 2 29
The 17th hp workstation fulfills three roles:
1. Application Server: This is the machine on which the application
runs. Graphics protocol based on OpenGL is sent to the 16 3D
systems via high-speed Gigabit networking.
2. Xserver: In addition to running the application, this machine also
renders the 2D X window system and responds to the keyboard and
mouse.
3. Compositor Controller: This machine controls operation of the
Compositor via an RS-232 serial connection.
The Compositor processes the DVI video from each hp fx10 card and
generates the output video. The Compositor can be programmed to
process the video input signals in a number of ways.
hp visualization center sv6 operating modes
The key to understanding the hp visualization center sv6 configurations
is to understand its three operating modes - Accelerate, Accumulate and
Mixed. These modes can be changed using the
/opt/graphics/OpenGL/sv/bin/setpipes command. In the
descriptions below, a “pipe” refers to a workstation that does 3D
rendering. A “channel” is the output sent to one output device.
• Accelerate Mode: Enhances rendering performance
Each pipe renders a fraction of the screen, thus speeding up
performance.
