mediaLib Library
To optimize compression on Solaris SPARC and Solaris x86 platforms, the Sun Shared Visualization 1.0 software uses Sun’s mediaLib™ library (libmlib). If your system does not have the SUNWmlib package installed, you can obtain the latest version from:
http://www.sun.com/processors/vis/mlibform.html
Additionally, the latest version of mediaLib has improved performance.
TurboVNC Started With the Gnome Window Manager
If Gnome is the user’s default window manager for new X sessions and a TurboVNC server session is started from within a local X session, then Gnome may fail to start in the TurboVNC session.
In this situation, the user sees the TurboVNC session as a grey or checkerboard background with an X pointer. Additionally, the TurboVNC log file might contain the following text:
In order to prevent resource conflicts, Gnome does not start if it detects that an existing X session is active. Gnome assumes this to be the case if the
SESSION_MANAGERenvironment variable is set.
The workaround is to mislead Gnome into thinking that no other X sessions are active. Do this by adding the following text near the top of your
$HOME/.vnc/xstartupfile:
Then, start a new Gnome session under TurboVNC.
Note –This workaround does not affect TurboVNC when it is launched in an SSh or Telnet session, nor does the error occur if a window manager other than Gnome is the default for new X sessions (such as CDE or KDE).
gnome-session: you’re already running a session manager
unset SESSION_MANAGER
Known Issues and Workarounds
CR ID 6429587 Rendering Errors and P20TimeoutError Message Can Occur After a DPMS Cycle
The Sun N1™ Grid Engine has a status and configuration GUI called qmon. If the Queue Control pane of the GUI is displayed and DPMS powers down the graphics accelerator, waking the system with a mouse movement might incur a
P20TimeoutErrorand might crash the window system.
This problem is resolved with the installation of patches 120927-05 and 120928-17.
See“Selected Patches” on page 3.
An alternative workaround is to disable board-level power management for the XVR-2500 graphics accelerator.
▼ To Disable Board-Level Power Management
1. As superuser, add the following line to the /etc/system file:
2. Reboot the system.
CR ID 6480887 Sun Ray Plug-in Does Not Encrypt Images
The Sun Ray server software can be configured to encrypt the network traffic between the Sun Ray server and the Sun Ray appliances. However, the network traffic between the VirtualGL Sun Ray plug-in and the Sun Ray appliances is not encrypted. The 3D images sent by the plug-in could be seen by someone who has access to the network and detailed knowledge of the Sun Ray protocols.
There are two workarounds available:
■ If the network between the graphics server and the Sun Ray server is inaccessible to intruders or otherwise protected, disable the Sun Ray plug-in by running the application with the vglrun -c 0 option. The images are sent to the Sun Ray server and encrypted before being sent to the Sun Ray appliance. There is a performance reduction with this workaround.
■ Generic network protection, for example, VPN, can be used for network traffic going from the graphics server to the Sun Ray appliance.
set kfb:p25_fbpm_supported = 0
Note –To prevent any users from inadvertently using the Sun Ray plug-in, remove the SUNWvglsr package from the graphics server.
Nondefault SGE_ROOT Requires Special Attention
If during installation or configuration you choose a different location for SGE_ROOT than the default of /gridware/sge, and if the Solaris software package SUNWsgeec is not installed on the Advance Reservation server host, the Advance Reservation facility needs your SGE_ROOT value. You must edit several files for the Sun N1 Grid Engine and Advance Reservation feature to function properly.
▼ To Edit the Files
1. Install the Sun N1 Grid Engine software and optionally configure for Advance Reservation.
2. As superuser, use an editor to edit the following files:
■ $SGE_ROOT/ar/bin/runar
■ $SGE_ROOT/ar/bin/SERVER
■ /lib/svc/method/n1gear(on a Solaris 10 or later system)
■ /etc/init.d/sgear(on all other systems) 3. Within the files, locate each occurrence of the string:
4. Replace each occurrence with:
whereyour_sge_root_pathis your specific Sun N1 Grid Engine root path.
Additional Functionality
The Sun Shared Visualization 1.0.1 Software includes a new reporting script, /opt/SUNWvrpt/bin/vis_report, that is helpful in debugging product installation, configuration, and usage problems.
Support engineers can use the script output to troubleshoot problematic behavior.
Use of the script is dependent upon the situation when the problem occurs:
/gridware/sge
/your_sge_root_path
■ VirtualGL– In most cases, run the script on the graphics server, ideally from the client host that attempted to use VirtualGL and as the user attempting to use VirtualGL.
■ TurboVNC– If using a TurboVNC session, run the script from within that session. The $DISPLAY and other environment variables will be set the same as when the problem occurred.
■ Advance Reservation– If the Sun N1 Grid Engine Advance Reservation facility is involved, also run the script on the host running the Advance Reservation server, as the owner of the $SGE_ROOT/ar/config directory.
Attach the output of the script to an email of your problem. Describe what you were trying to do, what you expected to happen, and what actually occurred. Send the email to your service provider or to [email protected].
Note – Because the reporting script is automatically installed with the Sun Shared Visualization 1.0.1 software, the Solaris package name SUNWvrpt or Linux RPM name sun-vis-report.noarch.rpm appears in the installation script output.
Documentation Notes
Sun Shared Visualization 1.0 Software Server Administration Guide
The following notes are in regard to changes to, omissions from, or errors in the Sun Shared Visualization 1.0 Software Server Administration Guide, 820-0233-10.
CD-ROM Installation and Removal Paths
In several locations in the book, the path to the installation and removal scripts is given as:
/cdrom/SSV1.0
This path might be incorrect for your operating system.TABLE 4lists the paths according to the operating system you are using.
X Proxies
In the section, “Raw or Proxy Mode” on page 5, references are made to X proxies other than VNC. Only TurboVNC is supported for use with VirtualGL’s Proxy mode, because of TurboVNC’s superior performance. Additionally, Raw mode can be used when the application and the X server are on the same host or connected by a high- speed, low-latency network, for example, Gigabit Ethernet or faster.
Modifying the kfbinit File not Necessary
If patch 120928-14 or later has been applied, the procedure, “To Modify the kfbinit File” on page 15, is not necessary.
Sun N1 Grid Engine Package Installation
In the procedure, “To Install the Sun N1 Grid Engine Software” on page 22, several steps have been updated.
Step 14
In Step 14, following the bullet “For Solaris automounting:”, replace Step a with the following:
a. Add the following line to the /etc/auto_direct file:
where /gridware is the base directory of your $SGE_ROOT.
Following the bullet “For Linux:”, replace Step a with the following:
TABLE 4 CD-ROM Installation and Removal Paths
Operating System Paths
Solaris OS /cdrom/ssv1.0
RedHat Linux /media/cdrom
SuSE Linux /media/SSV1_0
/gridware -rw,suid,bg,hard,noquota,intr nfsserverhostname:/gridware
a. Add the following line to the /etc/fstab file:
Step 16
Replace Step 16 with the following:
16. As superuser of the NFS server, install the Sun N1 Grid Engine packages into
$SGE_ROOT.
Also for Step 16, if you are installing Linux binaries, use a command similar to:
where platform is the architecture: amd64 or x86. When the installation script asks:
“Did you install this version with >pkgadd< or did you already verify and set the file permissions of your distribution (enter: y)”, answer n.
Step 18
In the second bullet of Step 18 of the same procedure, the installation script asks:
"Do you want to install Grid Engine as admin user >sgeadmin<?
(y/n)". This question might instead appear as:
"Do you want to install Grid Engine under an user id other than
>root<? (y/n) [y]".
Later, you are asked for the user ID, such as sgeadmin.
Network Automounting
The Note at the bottom of page 25 describes creating a symbolic link to automount every file system from the NFS server. The Note should also include the following text:
nfsserverhostname:/gridware /gridware nfs auto,suid,bg,intr 0 0
# pkgadd -d downloaddirectory packagename
gunzip -c n1geplatform.tar.gz | ( cd $SGE_ROOT ; tar xf - )
Use network automounting only if doing so also mounts suid. The Sun N1 Grid Engine requires certain components to be set-uid in order for qrsh to work properly.
SUNWvglsr Package not Needed for Client
In “Installing Sun Shared Visualization 1.0 Software” on page 31, the Note identifies packages that are not required for installation onto a client. The SUNWvglsr package is also not required.
Sun Shared Visualization 1.0 Installation
In the procedure, “To Install the Sun Shared Visualization 1.0 Software” on page 32, Step 1 describes the downloadable file and the installation directory it creates when unzipped.TABLE 5provides new information respective to your operating system:
Also for this procedure, Step 4 should read as follows:
4. If you are installing on the NFS server for your Sun N1 Grid Engine, answer y.
Otherwise, answer n and go to Step 6.
Device Permissions on a Solaris Graphics Server
For the procedure, “To Set Device Permissions” on page 41, the following Note should be appended as additional information:
TABLE 5 Operating Systems, Download Files, and Installation Directories
Operating System or
Other Download File Installation Directory
Documentation for any OS and platform
SharedVisualization_1.0_docs.zip Docs
Solaris SPARC, x86, and x64
SharedVisualization_1.0_solaris.zip SharedVisualization_1.0_solaris
Linux RedHat and SuSE
SharedVisualization_1.0_linux.zip SharedVisualization_1.0_linux
Windows XP SharedVisualization_1.0_windows.zip SharedVisualization_1.0_windows
Note – After configuring device permissions, all users can log in to the graphics console of the graphics server, for example, using a keyboard and monitor directly attached to the graphics server. However, running OpenGL applications on the graphic console is only permitted by users in the vglusers group.
Stopping dtlogin Ends X Session
In the procedure, “To Grant Access if Your Host Uses dtlogin as a Display Manager” on page 44, Step 4 has you stop dtlogin. This action ends any X session.
Alternatively, you can skip Step 4 until you have completed Step 13. Performing Step 4after Step 13 and then performing Step 14 effectively restarts dtlogin.
Adding Graphics to Sun N1 Grid Engine
In the procedure, “To Add Graphics to Sun N1 Grid Engine” on page 54, replace Step 1with the following text:
1. If the optional software was not already installed, as superuser, install the SUNWsge3Dpackage into your $SGE_ROOT directory.
Note – Ensure your $SGE_ROOT value is your answer to the installation prompt,
"Please enter your SGE_ROOT directory."
Location of Advance Reservation Log File
In “AR Server” on page 77, the Note provides the location of the Advance Reservation server output log file. For the Solaris 10 Operating System and later operating systems, the log file is located at:
/var/svc/log/network-n1ge_ar:default.log
Sun Ray Server Plug-in Text Change
In the paragraph following Figure A-5, replace the first sentence with the following text:
# pkgadd -d downloaddirectory SUNWsge3D
In this case, the best performance is still achieved by using the Sun Ray plug-in, which is the default. Alternatively, you can disable the Sun Ray plug-in so the Sun Ray server does the compression and transmission of the images to the Sun Ray clients.
Application Recipe Additions
Table 5-3, of Appendix B, should include the following rows for Java 2D™
applications that use OpenGL on Solaris SPARC platforms, and Pro/Engineer V3.0 on Solaris SPARC platforms:
Application Platform Recipe Notes
Java 2D
applications that use OpenGL
Solaris SPARC
When VirtualGL is used in conjunction with Java v5.0 (Java 1.5.0) to remotely display Java 2D applications using the OpenGL pipeline, certain Java 2D applications cause the OpenGL subsystem to crash with the following error:
thread tries to access GL context current to another thread
If you encounter this error, set the SUN_OGL_IS_MT
environment variable to 1 and rerun the application.
This issue does not exist in Java 6.
Pro/ENGINEER Wildfire v3.0
Solaris SPARC
When using Direct mode, set the environment variable
VGL_INTERFRAMEto 0 on the graphics server prior to
launching Pro/ENGINEER v3.0.
Pro/Engineer v3.0 frequently sends long sequences of glFlush() calls though nothing new has been rendered. The glFlush()calls cause VirtualGL to send long sequences of duplicate images into the Direct mode image pipeline. If interframe comparison is enabled, the overhead of comparing these duplicate images impacts Pro/Engineer performance when zooming in or out. Better performance is achieved by disabling interframe comparison and enabling VirtualGL’s frame spoiling functionality.
Sun Shared Visualization 1.0 Software Client Administration Guide
The following notes are in regard to changes to, omissions from, or errors in the Sun Shared Visualization 1.0 Software Client Administration Guide, 820-0234-10.
CD-ROM Installation and Removal Paths
In several locations in the book, the path to the installation and removal scripts is given as:
/cdrom/SSV1.0
This path might be incorrect for your operating system.TABLE 6lists the paths according to the operating system you are using.
Windows XP Application Installers
In several locations in the book, the installer for VirtualGL for a Windows XP client is called VirtualGL_version.exe. The correct filename is VirtualGL.exe.
Similarly, the TurboVNC installer for a Windows XP client is TurboVNC.exe. You can install either or both of these applications.
Server Name Correction
In “To Enable Secure Shell Access” on page 31, Step 2 and Step 3 should read as follows:
2. In the SSH™ session, set the VGL_CLIENT environment variable on the graphics server to point back to your client’s X display:
TABLE 6 CD-ROM Installation and Removal Paths
Operating System Paths
Solaris OS /cdrom/ssv1.0
RedHat Linux /media/cdrom
SuSE Linux /media/SSV1_0
my_server% setenv VGL_CLIENT sunrayserver:5.0
3. Verify that the X tunnel is configured between the graphics server and your client.
Type:
The DISPLAY should be defined and start with my_server.
Similarly, in “To Enable Secure Shell Access” on page 36, Step 2 and Step 3 should read as follows:
2. In the SSH session, set the VGL_CLIENT environment variable on the graphics server to point back to your client’s X display:
3. Verify that the X tunnel is configured between the graphics server and your client.
Type:
The DISPLAY should be defined and start with my_server.
Running the RUN.vncserver Script in the Background
In “Starting the TurboVNC Server Session Using a Script” on page 49, the command line could read:
my_server% echo $DISPLAY my_server:1.0
my_server% setenv VGL_CLIENT my_client:0.0
my_server% echo $DISPLAY my_server:1.0
my_server% /gridware/sge/graphics/RUN.vncserver &
Incorrect Description
In the procedure, “To Start the AR Client” on page 88, in Table 6-1, the description of the -serverHost is incorrect. The following is the correct description:
VirtualGL Options and Environment Variables
Table A-3, “General Values for VGL_ Environment Variables and vglrun Options”
on page 98, should include the following rows:
Accessing the Sun N1 Grid Engine Environment
In the procedure, “To Access the Sun N1 Grid Engine Environment” on page 107, Step 1and Step 2 have been updated.
TABLE 6-1 runar ReserveOptions
Option Description
-serverHost Name of host that is running the Advance Reservation server software. The default serverHost is configured by the Advance Reservation server administrator.
TABLE A-3 General Values for VGL_ Environment Variables and vglrun Options
Environment Variable Name
vglrun Command-Line Override
vglrun
Option Description
Default Value
VGL_LOG Redirect the console output from the VirtualGL
faker to a log file.
Setting this environment variable to the pathname of a log file on the VirtualGL server causes the VirtualGL faker to redirect all of its messages to the specified log file rather than to stderr. Output content includes profiling and trace output.
Print all messages to stderr.
VGL_INTERFRAME=0 VGL_INTERFRAME=1
Disables and enables interframe comparison.
Interframe comparison only sends tiles of the image that have changed since the previous frame.
This option has no effect in Raw mode.
Comparison enabled
Step 1
Step 1should read as follows:
1. Test the accessibility of the $SGE_ROOT directory from your client host:
Step 2
In Step 2, following the bullet “For Solaris automounting:”, replace Step a with the following:
a. Add the following line to the /etc/auto_direct file:
where /gridware is the base directory of your $SGE_ROOT.
Following the bullet “For Linux mounting:”, replace Step a with the following:
a. Add the following line to the /etc/fstab file:
# ls /net/nfsserverhostname/$SGE_ROOT
/gridware -rw,suid,bg,hard,noquota,intr nfsserverhostname:/gridware
nfsserverhostname:/gridware /gridware nfs auto,suid,bg,intr 0 0
