master mode - This is the workstation
where the master X server is run to control
all other rendering via the workstations
assigned to do 3D rendering (slave nodes).
This system also does all of the 2D rendering
for the entire screen.
mixed mode - In this hp visualization
center sv6 operating mode, the screen is
divided among the 3D slaves for accelerate
mode, but multiple workstations are
assigned to render each subdivision for
accumulate mode. This results in both
improved rendering performance and image
quality.
mini-sv6- Single channel systems with 3 or
7 slave rendering nodes. A second graphics
card in the master sytem is used as the
fourth or eighth 3D render node. Since there
are fewer j-class workstations, both the cost
and performance are lower than on standard
4-pipe or 8-pipe configurations.
module - The card inside the hp ProCurve
Switch. Also known as a ‘blade’. The official
product name is the hp ProCurve 100Base-T
Gigabit LAN Module.
panes - This is a setpipes screen rectangle
layout that assigns four large screen
rectangles to form a border around the
center of the screen. This allows for a greater
amount of the hp visualization center sv6’s
resources to be focused on rendering to the
center where the most intense rendering
demands are. The center of the screen can be
sub-divided by grid, horizontal slices or
vertical slices. The result of using this layout
is faster rendering performance.
passive stereo - Stereo capability where
no emitter is need. Uses a combination of
polarized glasses and special output display
devices (i.e. specially aligned projectors or
passive stereo work bench displays). The
glasses filter out the correct image for the
right and left eye. Two output cards must be
used for the compositor to produce the entire
left-eye scene and entire right-eye scene.
PDU - Power Distribution Unit on the rack.
Use these special power strips to plug-in
racked hardware.
pipe - A graphics enabled workstation.
Usually refers to a 3D slave node that is
rendering all or part of the screen.
pipe rectangle - A sub-division of the
entire display. Each of the areas receives
output from the group of 3D pipes assigned
to render to it. Select a layout using
/opt/graphics/OpenGL/sv/bin/setpipesor
the GUIs. Also known as a screen rectangle.
real estate - Describes the continuous
screen space spanning across multiple
display devices.
sample - In accumulate mode, each
graphics device is used to produce a slightly
jittered sample of the entire screen. The
compositor, to produce a higher quality
image, then averages those samples together
scalability - hp visualization center sv6 is
scalable in the sense that configurations
with larger numbers of can achieve higher
levels of performance and image quality. In
the case of the multiple display HP
visualization centers, more real-estate is
achieved.
screen - The area to which the entirety of
the output is sent. This can span more than
one monitor and be fed by more than one
graphics device.
