'''Note''': Tested on a standard compute node in HPC 3.0. Node already has CUDA 4.0 installed with a number GL based RPMs. Not sure if these are required:
<syntaxhighlight>
yum install libXi-devel libXmu-devel gcc kernel-devel gcc-c++ freeglut.i386 freeglut.x86_64 freeglut-devel glibc-devel kernel-source
</syntaxhighlight>

===== Installation Prerequisites =====
* Required libXaw and libXv
<syntaxhighlight>
# For turbovnc and virtualgl rpms
yum install libXv libXaw

# for a desktop environment
yum groupinstall "GNOME Desktop Environment" "X Windows System"
yum install xorg-x11-server-Xorg xterm firefox
</syntaxhighlight>
* Change runlevel to 5 and reboot. GDM needs to be running for vnc sessions to start up correctly.
* Setup xorg.conf using '''nvidia-xconfig'''

===== Install turbovnc and virtualgl =====
* Copies on PDD Applications (<file>\\srv-vfs2\PDD_DATA\Product Development\High Performance Computing\HPC Benchmarking\Applications|PDD Link</file>) or http://www.virtualgl.org/Downloads
<syntaxhighlight>
rpm -ivh turbovnc-1.0.1.x86_64.rpm VirtualGL-2.2.1.x86_64.rpm
</syntaxhighlight>

<syntaxhighlight>
vglserver_config +glx
usermod -a -G vglusers david
/opt/VirtualGL/bin/glxinfo -display :0 -c
</syntaxhighlight>

===== Setting up remote access =====
Use ssh for port forwarding:
* In this example
** '''vhpchead''' is the headnode used to access the cluster
** '''viscomp000''' is the node running vncserver which is used for remote visualisation
** '''10001''' is the port listening on your local desktop
** '''5901''' is the port listening for vnc connections on '''viscomp000'''
<syntaxhighlight>
# On one terminal
ssh -L 10001:viscomp000:5901 vhpchead

# Then on another local terminal
vncviewer localhost:10001
</syntaxhighlight>

===== HP RGS vs VirtualGL/TurboVNC =====
'''RGS limitations:'''
* HP hardware only (a problem for customers who want to keep things ‘open’)
* Only supported on Windows & RHEL (not SLES)
* Single session per server
* No dynamic resolution

'''VirtualGL limitations:'''
* Does not fully support the OGL standard
* No dynamic resolution
* The way it is run (requires “virtualgl” in front of the application command
