distribution system having a high impedance connection to
earth according to IEC 950).
rack stability
WARNING
14
To reduce the risk of rack instability:
•
Install the heavier hardware components at the bottom of the
rack, below the center of gravity for the rack. Never install
heavier components in the top or upper portion of the rack.
•
Make sure that the anti-tip plate is installed on the rack. Do
not remove the anti-tip foot from the rack.
•
Always extend the anti-tip plate before extending a
rack-mounted component for servicing.
•
Extend only one rack-mounted component at a time.
•
Do not stand or sit on any extended component.
•
Have all non-operator servicing done by qualified HP service
personnel.

power distribution units (PDUs)
A Power Distribution Unit (PDU) is equipment located in or near a
computer room which breaks down electric power from a high-voltage
source to appropriate levels of distribution to the central processing unit
and peripheral devices of a computer system. Figure 1-1 shows an
example PDU that is used with the HP product racks. This example is
the HP E7674A 16 Amp 100-240VAC PDU (part number A5137AZ).
CAUTION
Some components have been designed to be used with specific electrical
accessories such as PDUs. The use of any accessory other than those
specified is neither recommended nor supported.

PDU leakage current
WARNING
16
Due to the number of components that can be installed on one
Power Distribution Unit (PDU), there may be a risk of high
leakage current (>3.5mA). Reliable ground circuit continuity is
vital for safe operation of such components. To reduce the risk of
electric shock, connect each component to a grounded outlet
only. Never operate any component with its ground pin
disconnected from the socket of a grounded outlet.
Chapter 1
safety and support information
safety warnings
PDU power limitations
To reduce the risk of overload, do not exceed the rated load of any single
PDU. In addition, do not load a single NEMA 5-15 (see Fig. 1-3)
receptacle with more than 15 Amperes and any single IEC 320-1/C13
receptacle with more than 10 Amperes. In general, make sure that the
power source circuits are able to safely provide the current that will be
required by all components drawing power from them. This document
assumes that 220V and 240V cables are used.

metallic particulate contamination
Metallic particulates can be especially harmful around electronic
equipment. This type of contamination may enter the data center
environment from a variety of sources, including, but not limited to,
raised floor tiles, worn air conditioning parts, heating ducts, rotor
brushes in vacuum cleaners or printer component wear. Because metallic
particulates conduct electricity, they have an increased potential for
creating short circuits in electronic equipment. This problem is
exaggerated by the increasingly dense circuitry of electronic equipment.
Over time, very fine whiskers of pure metal can form on electroplated
zinc, cadmium, or tin surfaces. If these whiskers are disturbed, they may
break off and become airborne, possibly causing failures or operational
interruptions. For over 50 years, the electronics industry has been aware
of the relatively rare, but possible, threat posed by metallic particulate
contamination. During recent years, a growing concern has developed in
computer rooms where these conductive contaminants are formed on the
bottom of some raised floor tiles.
Chapter 1
17
safety and support information
safety warnings
Although this problem is relatively rare, it may be an issue within your
computer room. Since metallic contamination can cause permanent or
intermittent failures on your electronic equipment, Hewlett-Packard
strongly recommends that your site be evaluated for metallic particulate
contamination before installation of electronic equipment.

uses dedicated accelerators for rendering portions of a given screen. The
resulting renderings (called “screen rectangles”) are synchronized and
displayed as a single image through additional hardware.
hp visualization center sv6 is based on a client/server architecture called
Distributed Single Logical Screen (SLS/d). This technology transparently
manages multiple clients that render portions of a given screen. Each hp

visualization center hp visualization center sv6 cluster is made up of one
2D master node and a supported number of 3D slave nodes. The 2D node
is responsible for rendering the GUI and X11 rendering primitives. The
3D slave nodes, also called “pipes,” are responsible for rendering all or
some part of the 3D scene. The video output from each node is then
combined, or composited, to a single monitor.
To obtain multiple channels of output, multiple clusters can be used. A
“channel” refers to one output device, typically a monitor. This allows for
more screen “real estate” (two or three displays) by using multiple hp
visualization center sv6 clusters.

16-pipe system configuration
NOTE
Arrangement of the hardware in the racks may vary.
The 2D master system controls the rendering that happens on the 3D
pipes. The output of each pipe is then fed into hardware called the
Digital Compositor. The Compositor combines the inputs into a single
output stream to the display. A local high-speed Gigabit Ethernet switch
(hp ProCurve Switch) which connects the systems.
The Digi EtherLite-32 terminal server (D GZ1469C) is a low-cost option
for consolidating consoles. Each Digi switch provides remote access for
up to 32 systems. The Digi EtherLite driver runs on the master system.
Chapter 2
25
installation and user information
product overview
This driver communicates with the EtherLite-32 and makes the Digi
switch’s serial connections appear as though they were direct serial
connections to the master system. Thus, the master node communicates
with the slave node via a serial port communications program, such as cu
on HP-UX or the dinc program supplied with the Digi switch.
Examples for accessing save node #2:
cu -l/dev/ttyn01 -s 9600
/usr/local/bin/dinc /dev/digi/sv2
The Digi EtherLite-32 has its own IP address and is connected to the
10/100 hub. RJ45 ports are connected to serial port 1 of each slave node
via an RS-232 adapter.
Figure 2-3
Single Display Channel
Each workstation has one graphics card. The master workstation does
2D rendering and the rest of the workstations do 3D rendering. Each hp
visualization center sv6 cluster outputs to a single display. Each graphics
device is connected to the compositor through a digital video connection.
Each workstation is connected to the hp ProCurve 10/100 BaseT switch
(J4813A) which provides a connection to the site’s LAN.

hp visualization center sv6 architecture
This section discusses a general overview of how the hardware is used by
the hp visualization center sv6 architecture, using a 16-pipe system as
an example:
Figure 2-5
16-pipe System Architecture
The 16-pipe system contains 16 hp workstations j6000 (A5990A) or j6700
(A7278A) which perform the 3D rendering. Each of these machines
contain the hp fx10 Graphics Accelerator Card (A1299B). Each fx10 DVI
(Digital Video Interface) output connects to an input of the digital
compositor (A6061A).
28
Chapter 2
installation and user information
product overview
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.
Figure 2-6
Chapter 2
Accelerate Mode - Vertical slice, Horizonal slice and Grid
29
installation and user information
product overview
NOTE
Each fraction of the screen is called a “screen rectangle.”
Example: In a configuration with five workstations (one doing 2D
rendering and four doing 3D rendering), each 3D workstation would
output one of the four screen rectangle areas on the display.
You can specify how the screen is dissected. The basic options are
grid, vertical slice, horizontal slice and pane. See the
/opt/graphics/OpenGL/sv/doc/README.setpipes file for more
details.
•
Accumulate Mode: Improves Image Quality
Each pipe generates the complete screen, “jittered” by sub-pixel
values. These jittered images are averaged together to achieve a
better quality image. This mode is sometimes referred to as the
anti-aliasing mode. The more workstations you add, the more
samples can be taken, and the better the resulting image quality.
Figure 2-7
Accumulate Mode
•
Mixed Mode: Combination of both Accelerate and Accumulate
Modes
Each screen rectangle is generated (jittered and averaged) by the
number of samples designated. There is improved image quality
(anti-aliasing), and also improved performance (acceleration) since
each area is generated by multiple workstations.
30
Chapter 2
installation and user information
product overview
Figure 2-8
Mixed Mode
For example, with a 16-pipe hp visualization center sv6, each of the
quadrants pictured above could be accumulated by N graphics-enabled
workstations (N is equal to the number of samples to be jittered). If N=4,
then you get four samples for accumulation on each section and since the
screen has been split into four sections, you also get improved
acceleration.
To increase the rendering performance, use the Accelerate Mode. To
increase image quality, use Accumulate Mode. To improve both,
experiment with Mixed Mode to achieve the desired balance of both.
Figure 2-9 shows the hardware arrangement needed to produce the
output in Figure 2-8.

** Mini-sv6 configurations have slightly lower performance because their second
master node doubles as a 3D render node using its 2D HP fx10 graphics card.
Given enough 3D pipelines, both acceleration and image quality can be
achieved. With 16 systems, the screen can be split into four screen
rectangles. Four workstations can be assigned for each quadrant to
produce four samples per pixel from full scenes jittered by sub-pixel
values. The digital compositor can both average these values into a
single value and recombine the four quadrants into a single image. The
possible configurations include:

http://managementsoftware.hp.com/products/swdist/ for details on HP
Software Distributor usage.
WARNING
When installing patches that require a reboot, switch to a
stand-alone workstation X server instantiation. If you wish to
use the SD GUI tools instead of the command line or terminal
versions, either login remotely to perform the install, or
configure the X server to run as it would on a stand-alone
workstation. (Example: Temporarily move the /etc/X11/X0screens
file to X0screens.save then restart the X server.) Failure to do
this could result in an incomplete installation. On sv6, when the
first slave node reboots, it kills the X server on the master node,
which kills the remaining swinstall GUI windows.
NOTE
The examples below assume a single-channel system with a master
gigabit hostname of svm and an example patch number of PHSS_25612,
which is in tape depot format. Make appropriate substitutions as needed.
Here is a summary of the following installation steps:

•
Download and unpack software.
•
If the software requires a reboot, change to a stand-alone
workstation X server.
Chapter 2
installation and user information
updating software
•
Add /var/opt/ignite/sps/sv6_files to path.

•
swcopy
•
swinstall
step 1: preparation
1. Back up your system before installing a patch.
2. Login as root.
3. Add the sv6files directory to your path to access helpful scripts.
Example:
export PATH=$PATH:/var/opt/ignite/sps/sv6files
4. Download software to a temporary directory on the master node.
Example:
Save As /tmp/PHSS_25612
Before installing, observe any special instructions or patch
dependencies.
Individual HP-UX patches are available at http://itrc.hp.com
5. Unpack compressed packages if necessary.
Example:
cd /tmp
sh PHSS_25612
6. Set root access permissions for SD (Software Distributor) tools.
Verify that you have a recent version (PHCO_23966, PHCO_25875,
or newer) of the software distributor tools, which have the ability to
install to multiple targets.
swlist |grep SD
Chapter 2
51
installation and user information
updating software
Use the default target list which is generated during the initial
installation of sv6 systems, /var/opt/sps/sv6files/sv6_targets, or
create a new file containing the gigabit hostnames of all systems in
your sv6 configuration. The first name in the list must be the gigabit
hostname of the master system. For single-channel configurations,
the default master hostname is svm, and for multi-channel the
default is svm_c1. For this example, our sv6_targets file contains:
svm
sv1
sv2
sv3
sv4
Touch the .sdkey file on each system to allow for the SD “install to
multiple targets” functionality. Use the /var/opt/ignite/sps/sv6files/all
script to automatically run this command on all systems in the
targets list.
all touch /var/adm/sw/.sdkey
Enable SD root permissions from the master system to all systems in
the target list.
master=$(head –1 /var/opt/ignite/sps/sv6files/sv6_targets)
all /usr/sbin/swacl -l root -M user:root@$master:crwit
step 2: copy and register locally
This step meets the requirement of the SD “install to multiple targets”
functionality. The patch or depot being applied must be registered on the
local (not network mounted) hard drive of the master system. Tape depot
format is not supported. The swcopy command converts tape depots into
an acceptable format.

An additional X server called the ‘head’ controls the other X servers. In
addition to the master X server, the head X server is run on the first
master workstation listed in the /etc/X11/X0screens file. This simply
adds one more layer to the X server hierarchy. The head X server controls
the master X servers running on each 2D node. The master X servers
control the slave X servers running on each 3D slave node. Notice in the
following 8-pipe, 2 channel sample X0screens file, that each hp

additional equipment
A separate hp visualization center sv6 cluster must be added for each
additional channel of output, as desired.
A continuous chain, starting at the master system (M) which is the 2D
pipe in the first rack, connects all workstations. The chain is formed by
synchronization cables between the racks. See the diagrams below.
Figure 2-16
Synchronization cable chain
configuring offset overlap
When running a configuration where the output is displayed by
projectors, it is often necessary to overlap the output channels to ensure
proper video intensity across the entire display (see Figure 2-22). Edit
the /etc/X11/X0screens file to include the following ScreenOption to
specify the amount of each screen to use for blending:
SlsScreenBlendOffsetPercent 25
Chapter 2
57
installation and user information

Figure 2-17
Edge Blending
This raises the intensity of the pixels on the edges of the physical screens
so that the overall projected image is consistently bright. These blending
options are only meaningful in multi-channel configurations. The default
is to not enable screen blending
SlsScreenBlendOffsetPixels is similar to SlsScreenBlendOffsetPercent,
except you specify the exact number of pixels to blend instead of a
percentage of the screen width. Specify either pixels or a percentage.
These two options are mutually exclusive.
configuring offset overlap for multiple rows
The previous edge-blending example shows a simple three-channel configuration with one row and blending between the three columns. For
blending of multiple rows, also add one of the following ScreenOptions to
specify the amount of each screen to use for blending between the rows:
SlsScreenBlendHeightPercent <percent>
SlsScreenBlendHeightPixels <pixels>

In addition to the standard CDE patterns, your hp visualization center
sv6 system comes with special high resolution CDE backgrounds for
configurations with two or three display channels.
The following files are for use with the HP-UX Common Desktop
Environment (or CDE). They are formatted as pix map files to be used as
backdrops for a user’s account.
1. Choose the desired resolution file from /.dt/backdrops
2. Select the Backdrop option from the Style Manager
3. It may take some time to open the menu as CDE first scans the large
files and adds them to the file browser. Open the menu when ready.

This section covers some general tasks the hp visualization center sv6
user may do. If you are looking for descriptions of hp visualization center
sv6 tools, skip to the How To Use hp visualization center sv6 Tools
section.
•
X Server
To start the X server on the master system, run X:0 or go to init 3
to start up the X server and CDE. The master’s X server will
automatically start and control all slave X servers on the other
systems.
To kill the X server, press <Ctrl>+<Shift>+<Break>, then wait for
the X servers to stop.
Press <Ctrl>+<Shift>+<Break> again.
Press enter a couple of times to get the prompt back.
•
X0screens Description
The /etc/X11/X0screens file details the X server configuration
information for the HP X server. The X0screens file is used to
configure many aspects of hp visualization center sv6 including
which systems are to be involved in the hp visualization center sv6
configuration, video timing data, and options to obtain diagnostic
information.
The X0screens file on the hp visualization center sv6 master system
is used to configure the X servers on each of the hp visualization
center sv6 slave systems. This single-file configuration maintains
consistency between all nodes.
NOTE
This file must be edited as root and must be located in
/etc/X11/X0screens
•
Loading X0screens templates
A template /etc/X11/X0screens file is on the master system.
There are several additional X0screens template files available. Copy
or link the desired (and compatible) template to X0screens. For
62
Chapter 2

instance, if you have a three channel system, but you want to
temporarily set the configuration to use only two of the channels, you
could save the current X0screens file and move a two channel
template into place:
cp /etc/X11/X0screens /etc/X11/X0screens.orig
cd /usr/lib/X11/Xserver/misc/slsd/templates
cp X0screens.p16c2 /etc/X11/X0screens
. . . or
ln -s /etc/X11/X0screens.16c2 /etc/X11/X0screens
NOTE
Early versions of SLS/d required the /etc/X11/X0devices and
/etc/X11/X0screens files on the slave systems to be edited. This is
no longer necessary, since the master system uses the information in
its X0screens file to do automatic configuration on the slaves via the
X server.
changing resolution
Use one of the methods below to specify the resolution in the
/etc/X11/X0screens file. Each method automatically sets all graphics
cards in the hp visualization center sv6 configuration to the specified
resolution. If no video timing information is specified, the default
settings will be used.
Do not use the setmon program to change resolutions on your systems. It
does not have the functionality to change all necessary settings.
•
Standard Resolutions:
To set a standard resolution, add the following lines to the
ScreenOptions section of the /etc/X11/X0screens file. The
example below is the default for fx10 graphics cards in an hp
visualization center sv6 configuration (1280x1024 at 75 Hz):
ScreenOptions
SlsdVideoTimingWidth 1280
SlsdVideoTimingHeight 1024
SlsdVideoTimingFrequency 75

Customized Resolutions:
If you wish to customize to a non-standard video format or specify
precise timing parameters:
Select one of the video timing files from
/usr/lib/X11/Xserver/misc/slsd/videotiming
Reference it in the /etc/X11/X0screens as follows:
ScreenOptions
SlsdVideoTimingFile
/usr/lib/X11/misc/slsd/videotiming/<timingfile>

The following tools can be used to make on-the-fly configuration changes.
•
sv_config -This script allows you to customize the site-visible
host names and IP addresses for slave systems. It is not necessary to
set the IP addresses on the slave systems for the system to operate
properly. Use this script to set root passwords on the slave systems.
This is only necessary if you want access to these systems for other
uses.
First, you must know the new host names and IP addresses for all
the systems, including the IP address of the Digi-Etherlite terminal
server. When you have this information you can run sv_config
(/var/opt/ignite/sps/sv6files/sv_config) and it will
prompt you for the new information for each system.
You may also prepare a file with this information for sv_config to
read. First copy the sv6_targets to a temporary file (for example:
cp /var/opt/ignite/sps/sv6files/sv6_targets
/tmp/sv6_newnames). Then edit /tmp/sv6_newnames to add the
required information. It should look like the example below:
svm
sv1
sv2
sv3
...
Append after each sv name the hostname and IP address you want
the system to be known as within your site network. The first line
(svm) is the master system, sv_config doesn’t change the master’s
hostname or IP address, use set_parms to do that. sv6_newnames
will then look like this:
svm mymastername 111.222.123.1
sv1 myname1 111.222.123.2
sv2 myname2 111.222.123.20
sv3 myname3 111.222.123.17
.
Then run ./sv_config -f /tmp/sv6_newnames
Chapter 2
65
installation and user information
how to use hp visualization center sv6 tools
sv_config will then use that file to determine how to set each
system’s hostname and IP address. It will then ask you to enter the
IP address for any Digi-Etherlite Terminal servers you have. Once
all the data has been collected the changes are made to the systems
and sv_config asks to reboot. A reboot is needed for all the
changes to take effect. If you are not able to reboot at this time you
can use sv_config -rebootall
sv_config always saves the files it will be changing so that the
system can be restored later. Use sv_config -restore to put the
saved files back in place.
NOTE
This does not change the Gigabit Ethernet hostnames or IP
addresses.

installation and user information
how to use hp visualization center sv6 tools
The setpipes program modifies the location and size of the
rendering area for each 3D Slave. In addition, the number of jitter
samples per 3D Slave can also be specified.
NOTES:1) When experimenting with different values in xdist and
ydist, it is possible that the values will not total 100% of the
screen width or height. In this case, the command will be executed
and the compositor will display a test pattern in the areas not
covered by a pipe. The test pattern is a block grid pattern that
rotates between red, green, and blue continuously.
2) When running setpipes on an sv6 VisCenter configuration, the
"-" is optional between the master specifier (e.g, "-0") and the
Pipe orientation (e.g., grid). In other words, on an sv6 VisCenter:
setpipes -0 grid -1 grid
is identical to
setpipes -0 -grid -1 -grid

stereoscopic viewing
This section covers basic installation issues for stereoscopic viewing
options. Please consult your chosen provider for complete details on their
products.
active stereo overview
Most output devices are only compatible with active stereo. For active
stereo, only one output card per digital compositor (A6061A) is needed.
Synchronized emitter and stereo eye wear are connected to the controller
card on the digital compositor.
Hardware:
•
One digital compositor output card for each channel.
•
Monitor or other standard output device.
•
Stereo Emitter(s) and eyewear synchronized to block out left or right
eye at appropriate times.
See http://www.hp.com/go/workstations for an overview of immersive
environment products and hp visualization center sv6 certified output
devices.
passive stereo overview
Most output devices use active stereo as described above. With the
passive stereo capability, no emitter is needed. It uses a combination of
polarized eye wear and special output display devices (such as, specially
aligned projectors or passive stereo work bench displays). Two output
cards must be used for the compositor to produce the entire left-eye scene
and entire right-eye scene. Both scenes are overlapped. The polarized eye
wear filters out the correct image for the right and left eye.
Hardware:
74
•
Two digital compositor output cards per channel.
•
Output device that supports passive stereo.
•
Polarized stereo eye wear.

installation and user information
stereo hardware installation
stereo hardware installation
The following steps are recommended for installing stereo hardware
packages for use with a multi-channel hp visualization center sv6
solution. The same principles apply to single channel configurations.
1. Unpack and inventory components
Emitters should have a stereo-sync BNC type connector and a 9-pin
D-sub connector for the separate power transformers. BNC coaxial
type cables are necessary for signal transfer between the graphics
card and the emitters. BNC “T” connectors are often used to split
stereo signals from the controller card on the compositor to several
emitters.
2. Ensure eye wear is functioning and clean
Follow the manufacturer’s suggestions for cleaning the eye wear.
3. Position emitter in viewing area
For hp visualization center sv6 systems that use monitors as display
devices, one emitter is usually sufficient for small groups. The
emitter is usually placed strategically on top of the user’s console
monitor(s) in the center of the user’s direction of gaze.
If more than one emitter is needed, they are usually positioned such
that the coverage angles (approximately 90 degrees horizontal arc,
40 degrees vertical arc) are sufficient for audience members to “see”
at least one infrared emitter when viewing a screen.
Always ensure that the sight line between an emitter and sensor on
the eye wear is unobstructed from all relevant angles of view.
4. Connect emitters to the Compositor
Recommended signal distribution from the graphics cards to
emitters is from a single point (the compositor controller card on the
master system) to the emitters. Emitters are serially connected
(daisy chained) with “T” BNC connectors using coaxial (BNC tipped)
cables between emitters.
Under normal circumstances, the master system’s compositor drives
one active stereo emitter. Greater numbers of emitters or longer
cable lengths may require signal amplification. Consult the stereo
equipment vendor for more information
Chapter 2
75
installation and user information
stereo hardware installation
Connect power supply transformers to their respective emitters at
this stage. As with all computer equipment, emitters should be
surge-protected from hazardous power spikes wherever possible.
CAUTION
It is recommended that all emitters be powered OFF when
connecting or disconnecting their cables to any other equipment.
This can reduce the possibility of harmful power surges to other
equipment when handling this signal source.
5. Power up the emitters
The power switch for emitters is located on the back side of the
device. The switch has three positions -- high, off, and low power. It is
recommended that you use the high power position to improve signal
performance, especially in rooms with high ambient light or that
accommodate larger audiences.
changing to stereo monitor mode
Use the following instructions to change graphics cards and compositor
settings to a stereo mode.
1. Add ScreenOption
log in to the master system as root
init 2
In addition to the SlsdVideo resolution settings or the videotiming
file specified in /etc/X11/X0screens, add one of the following lines
under the ScreenOptions section:
SlsdCompositorStereo Active
SlsdCompositorStereo Passive
Save the /etc/X11/X0screens file
2. Start up the new X server:
init 3
This will set all graphics cards in the configuration to the new stereo
setting and then bring up CDE.

Application suggestions
— Applications that primarily use display lists for rendering,
perform best on the hp visualization center sv6 systems.
— The use of vertex arrays by the application can also be helpful in
cases where it is not possible to use display list.
— Immediate mode applications are likely to run slower because of
the excessive network traffic. Use pass through mode to
overcome this issue.
•
Using NFS to mount hard drives
— All applications and models should be installed on the master
system for the best performance
— If extra disk space is needed, adding an additional hard drive to
the master system is recommended. As an alternative, the hard
drives of the slave machines may be mounted using the standard
NFS commands or by running HP’s System Administration
Manager (SAM) as follows:
CAUTION
This may slightly increase the wait time during loading and
hard drive access.
— Run SAM; choose Networking and Communications,
Networked File Systems then Export or Mount the hard
drive you want to share.

Optimizing performance
For each application and model type, try experimenting with some
different screen layout x and y offsets and other setpipes options. By
adjusting the pipe rectangle slices to fit the model’s proportions, you
can maximize the rendering performance.
78
Chapter 2
installation and user information
optimization
— Accelerate Mode - See the README.* setpipes files for
instructions for specifying a screen layout in accelerate mode.
/opt/graphics/OpenGL/sv/doc/README.*setpipes
— Panes - In this screen layout, the center of the screen is
sub-divided into one of the basic layouts: grid, horizontal slices,
or vertical slices. Four larger screen rectangles form the outside
borders of the screen. Use one of the setpipes tools to select the
panes layout. By putting the smaller screen rectangles over the
center where rendering demands will probably be greatest, you
can achieve faster performance.
At this time, this functionality only works for 8- and 16-pipe
systems. For 8-pipe configurations (accelerate mode only) set
samples=1, and for 16-pipe samples=2 (mixed mode only).
In this 16-pipe example, there are two 3D rendering nodes
accumulated to display to each screen rectangle. More of the
computing resources are focused on the center where there is
more geometry to be rendered
Figure 2-23 Panes
— X and y offset adjustments - Use the xadvsetpipes tool (see
/opt/graphics/OpenGl/sv/doc/README.xadvsetpipes) to
adjust the size of the screen rectangles. Place the smaller
rectangles over the areas where rendering demands will be the
greatest. For example, you may choose to expand the top screen
rectangle to be very large if that region doesn’t have very much
geometry as pictured in Fig. 2-26.

Figure 2-24 X and Y Offset Adjustments
— Environment Variables - use the following environment
variable to measure and compare performance:
HPOGL_LOG_FRAME_RATE - Is an application environment
variable, which can be used to get a display of the frame rate for
bench marking and performance comparisons.
On the master system at a command line prompt:
export HPOGL_LOG_FRAME_RATE=1
From the same prompt, run the application you wish to measure
Move something in the application window and watch for frame
rates in the window where the prompt is.
When finished:
unset HPOGL_LOG_FRAME_RATE
Pixel Zoom - when HPOGL_DSM_DISABLE_FAST_ZOOM is
enabled, the OpenGL Pixel Zoom rendering reverts to its
previous slower behavior. If you want to determine the amount of
this Pixel Zoom performance tuning, set this environment
variable and compare with not setting it. This feature was
released in software version 0201 in January 2002.
Example:
To see the slower mode:
export HPOGL_DSM_DISABLE_FAST_ZOOM=1
80
Chapter 2
installation and user information
optimization
The default is for fast zoom to be enabled. To put it back to its
original setting:
unset HPOGL_DSM_DISABLE_FAST_ZOOM
The environment variable HPOGL_OPT_CACHE_MATRICES can be
used with any application, but has the most impact on
applications that benefit from matrix caching. Matrix caching is
an optional client side optimization that detects successive
glPushMatrix(), glMultMatrix(), render, render,
glPopMatrix()sequences where the exact same matrix is
redundantly sent.
To enable this feature, set the environment variable before
running the application:
export HPOGL_OPT_CACHE_MATRICES=1
•
Optimizing image quality
By adjusting the number of pipes used for accumulation (using
setpipes) and turning on hardware scene anti-aliasing (described
below), you can maximize the image quality.
Accumulate Mode - See the
/opt/graphics/OpenGL/sv/doc/README.*setpipes files for
instructions on specifying an accumulate mode screen layout. This
can be done with either a GUI or via command line options.
There are two methods of turning scene anti-aliasing on and off for
fx10 graphics cards in your hp visualization center sv6 workstations:
Method #1:
The environment variables, HPOGL_FORCE_SCENE_AA and
HPOGL_FORCE_SCENE_AA_DBL can be used by any application
without any code changes. The first one forces all 24-bit OpenGL
rendering to be scene anti-aliased and the second one restricts scene
anti-aliasing to only double buffered visuals.
This will turn on scene anti-aliasing for all OpenGL applications. To
enable one of these, add it to the Environment section of the
/etc/X11/X0screens file then restart the X server.
Method #2:
An application can turn on/off scene anti-aliasing on the fly by using
the OpenGL calls:
Chapter 2
81
installation and user information
optimization
glEnable(GL_SUPERSAMPLE_HP);
glDisable(GL_SUPERSAMPLE_HP);
CAUTION
Depending upon application frame rates and window size, enabling
scene anti-aliasing can impact performance significantly. With low
frame rates and/or small windows, the performance impact is minor
(5% or less). Also, when scene anti-aliasing is turned on, there is
much less fx10 memory available for caching texture maps, so this
can also impact rendering performance.
pass through mode
Applications that run in OpenGL immediate mode rather than running
in display list mode do not scale well in performance. Immediate mode
applications tend to run slower when executed on the sv6 architecture
due to excessive network traffic.
To provide the best performance for immediate mode applications
running on sv6 systems, a special mode called “pass through mode” has
been implemented. When an application runs in pass through mode on
an sv6 system, it bypasses the sv6 architecture and runs as if it were
executing graphics on a standard workstation. This is the optimal mode
for executing immediate mode OpenGL code on an sv6 configuration.
To enable pass through mode, simply set this variable right before you
run the application then unset it before you start any other applications
from the same shell:
Example (for Korn Shell):
export HPOGL_PASS_THROUGH=1
/applications/abc/run_abc
unset HPOGL_PASS_THROUGH
or (for C Shell)
setenv HPOGL_PASS_THROUGH 1
/applications/abc/run_abc
unsetenv HPOGL_PASS_THROUGH
82
Chapter 2
installation and user information
optimization
WARNING
Do not add this environment variable to /etc/X11/X0screens. That
would disable all scaling for everything rendered to the screen.
By applying it only to the desired application, you can leave
scaling enabled for everything else not inside the immediate
mode application’s windows. In short, you should never set this
variable so that it is applied to your user or system environment.
It MUST be applied specifically to the invocation of applications
that require it. A good way to do this is to set it in a script, which
invokes the application.
gamma correction in pass through mode
The hp visualization center sv6 supports 3-channel gamma correction
(i.e. red, green, and blue can all be controlled individually). However,
pass through mode only allows for 1-channel gamma correction. To allow
for normal sv6 mode and pass through mode to co-exist, the pass through
mode simply uses the sv6's red gamma channel as the pass through
gamma correction value for red, green, and blue.
pass through mode on a multi-channel sv6
A side effect of pass through mode is that an application cannot use the
full area of a multi-channel display such as a power-wall. This is because
the application is operating exactly as it would on a standard desktop
workstation, and so it has no access to the sv6 channels, which are driving other monitors or projectors in the display. The result of this is that
an application in pass through mode is constrained to the area of the display handled by the channel driven by the application master workstation. Typically, for a two- or three- channel system, this is the left-most
channel. Furthermore, if the display is projected and uses edge-blending
technology for a seamless image, the overlap region may prove
out-of-bounds too, because the brightness of the application’s window
will fall off as it approaches the edge of the channel (because its pixels
are not duplicated in the channel next to it). Therefore it may be necessary to resize the window a little to ensure that it doesn’t enter the blend
region.
Note that applications that do not require pass through mode can use
any region of the full multi-channel display, and are not affected by pass
through applications that may be running at the same time.
Chapter 2
83

optimization
gamma value
Another way to fine-tune the image quality is to adjust the gamma
correction. Specify the default values to be used for 3D gamma
correction. using the instructions in the
/opt/graphics/OpenGL/sv/doc/README.gamma file.
HPOGL_PUSH _ENVIRONMENT
To override the default environment specified in the SlaveEnvironment
section of the /etc/X11/X0screens file, have the application startup
script set HPOGL_PUSH_ENVIRONMENT.
By setting HPOGL_PUSH_ENVIRONMENT, all HPOGL* environment
variables are passed across to the slave nodes. With this mechanism,
each application can have its own individual environment. In the
absence of HPOGL_PUSH_ENVIRONMENT, slave environments
default to X0screens settings at the time that the Xserver was started.
As an example, assume X0screens has:
SlaveEnvironment
HPOGL_FORCE_SCENEAA=1
HPOGL_LIGHTING_SPACE=EC
Application abc’s startup script contains:
export HPOGL_BOUNDING_VOLUME_ENABLE=1
export HPOGL_BOUNDING_VOLUME_GLOBAL=1
export HPOGL_BVOL_MIN_VERTS=5
export HPOGL_BVOL_MAX_VERTS=10
export HPOGL_PUSH_ENVIRONMENT=1
/opt/apps/abc
For this example, application abc will run with the four variables set in
its environment and WILL NOT have HPOGL_FORCE_SCENEAA or
HPOGL_LIGHTING_SPACE=EC set.
Any other application that is run without
HPOGL_PUSH_ENVIRONMENT will have only the X0screens values.

component designed specially for scalable visualization. It consists of a

rack mountable box containing a fourteen-slot backplane. Into the
backplane, three types of cards can be inserted: a controller card, an
input card and output cards.
compositor cards
The compositor must contain one controller card. It is responsible for
initializing the system, updating firmware, and communicating with the
master Workstation to update state information (mode, video rates, video
stream state, etc.). This card also accepts the stereo sync signal from the
graphics card on the master Workstation and produces the stereo sync
needed by active stereo emitters. It also controls the power switch, fan,
and status LEDs. After initialization, it only monitors the fan, power
supply, and sets the LEDs.
The input card has connections for two video input streams. In a scalable
visualization system, one input is used for the 2D stream while the
second input on that card is used for 3D. Some number of additional
input cards are used for 3D streams. The input card is responsible for
taking in digital video streams, down-sampling the data (in
super-sample scene anti-aliasing mode) and inserting the data into the
appropriate location of an internal frame buffer (in all modes) while
summing the data with the original frame buffer contents (in jitter scene
anti-aliasing mode). This frame buffer is then sent to the next input card
for insertion of its data. The final stage is for the 2D channel to
optionally average the data (divide by the number of 3D input streams
when in jitter mode), overlay its 2D rendering stream data and mask off
the non-3D data from the previous input cards.
The output card takes the composited image and produces a digital or
analog output signal that is appropriate for the display on a flat panel or
monitor. For a given display there can be two output cards. Two are used
to convert the sequential left/right image data from active stereo into a
parallel left image and a right image needed for passive stereo. To
support this, output card #1 has a frame buffer for holding the left image
while output card #2 receives the right image. When the correct left and
right images are completely received they are displayed simultaneously
while new left/right images are received.

sv6 compositor frame delay
sv6 compositor frame delay
This feature allows you to control when video frames are sent to the
output device. The compositor is instructed to delay the output of the
left-most (when viewed from the rear of the system) output card by one
frame.
Some digital projectors internally delay the video display by one video
frame. If a display is also connected to an hp visualization sv6 system,
the display will be one frame ahead of the projector video. In many cases
this is not an issue. However, if the compositor is driving an active stereo
display (using stereo emitters and active glasses) the projector is
displaying one eye, and the display is displaying the other eye at the
same time. Using a single set of emitters, it is not possible to get an
accurate stereo image on both the projector and the display.
Enabling frame delay tells the compositor to delay the output of the
video signal going to the display device, thus causing the display and
projector to match.
To enable this feature:
1. Add the ScreenOption SlsdCompositorEnableOutputFrameDelay to
/etc/X11/X0screens.
2. Connect the display to the left-most (when viewed from the rear of
the system) compositor output card.
3. Connect the projector to the right-most (when viewed from the rear
of the system) compositor output card.
4. Move the stereo emitter connectors from the back of the compositor
to any fx10 graphics cards in the sv6 workstations. This shifts the
emitter signals by one frame so they’re in synch with the output
devices.
5. Update to April 2002 or later sv6_enhancements software.

hp scalable visualization digital compositor
compositor self-test sequence
compositor self-test sequence
introduction
All compositor cards are assumed to be fully functional before they are
installed in a compositor chassis. They are all individually and
functionally tested at the manufacturer. Once they are installed in the
compositor backplane, however, they could fail by not being seated
properly or by having bent bus pins. This test is a check of backplane
connections to ensure that they are functional. This test is simply pass /
fail, with the only feedback being which card failed.
interface
This test uses the standard serial communications to the Field
Programmable Gate Arrays (FGPA) on the controller card. Both
controller FPGAs have registers allowing the controller to read the data
values on the video data bus input pins. One of the two FPGAs also has
the ability to drive a test value onto its video data bus output.
procedure
This test is performed as part of the compositor initialization on
power-up. First, the controller steps through all of the slots on the
backplane, identifying the card type. At this point. invalid configurations
are identified. Invalid configurations consist of configurations that have
an output card with no card before it or an input card that has no card
after it.
If the configuration is valid, then all cards are programmed. Card
programming is verified by a successful serial transfer to each FPGA
after programming. If a card fails the serial transfer test, it is identified
as a failure. If one or more FPGA fails the serial transfer test, compositor
initialization is aborted, and the failing cards are identified.
The ability of the cards to be configured and then communicate, tests all
of the control signals to the cards. The video data bus remains to be
tested. The controller tests these signals by instructing each FPGA to
drive a specific bit pattern onto the video data bus, using the bus test
registers. These test values are then read by the following I/O cards, and
Appendix A
105
hp scalable visualization digital compositor
compositor self-test sequence
the values should match. If the value does not match, two failing cards
are identified, the one driving the test value and the one receiving the
test value, as it is impossible to determine which of the two cards has the
failing bus connection.
testing output or input cards
The test can have two results. One is success. The other is failure, along
with a list of one or more cards that failed. This result is accessible to the
host through the compositor protocol. The result is also available without
the host. A successful test puts the cards into normal operation. If the
test fails, the speaker on the compositor sounds a long, low-pitch, failure
beep. If the controller has the ability to talk to the failing card or cards, it
will set the LEDs to red. This way the operator will be able to visually
identify failing cards.
testing controller cards
This procedure does not do any specific test of the controller card
backplane connections. Being a single connector, and having a position
that is the same for all configurations, it is believed that failure of the
card upon installation is unlikely. In the event there is a bent pin or a
poorly seated controller card, it is likely that the controller card will not
function at all, since it controls the power switch and the processor that
can test the other cards. Although very unlikely, it is possible that an
input or output card that fails the test may actually be a failure of one of
the pins on the controller card.
The test procedure depends of a few of the bus connections in order to
detect that a card is present in a slot. If one of these critical signals is
shorted or open, the test may miss a failure by not knowing that a card is
even in the slot, or the test may misidentify a card.

hp mini-sv6 configuration
The mini-sv6 system is a low-cost, single channel configuration. An
additional graphics card is installed in the j6700 master system which
takes the place of a 3D render node. The other three render nodes are hp
b2600 workstations.

This configuration allows a trade-off between the amount of rendering
performance and cost. It falls between a stand-alone workstation and a
standard 4-pipe sv6 configuration. For many uses, such as conference
room demonstrations, this is the perfect amount of cost/performance
scaling.
