Glossary 119 | HP sv6 guide

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

glossary

screen -

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/setpipes or 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.
