The remote visualization node is part of the CCR general
computing cluster. This node can be accessed from outside the
cluster. Access restrictions are the same as the general CCR
compute cluster. If you are not on campus, you must connect
through the VPN.
The node has 12 cores, 256GB of memory and 2 Nvidia Tesla M2075
*NEW - Jan 2014 * The visualization node has been
integrated with Slurm. As such, each allocation to use this
resource will initiate a Slurm batch job. The limits for this
job are set to be 24 hours of wall time. After this time limit is
reached, your remote visualization session will be terminated and
the resource released for other users.
This node can be used when there is a need to use an OpenGL
application GUI with access to the CCR Cluster resources.
The procedure described below will allow OpenGL software to run
in a hardware accelerated mode on the visualization node and
display the application on your local workstation. It should
behave as if you were running the application locally in terms of
performance. A side benefit of this scheme is that the
connection is VNC based, such that you can disconnect and connect
to the display at any time without terminating your job.
The node runs the NICE Remote Visualization software suite.
Use the following procedure to install the client software
and connect to the server.
- Connect to : https://viz01.ccr.buffalo.edu/enginframe/demo/showcase
- If prompted, choose to “accept certificates”,
“add exception”, “continue anyway”,
“understand the risks”, etc.
- Click on the “Log-in” link located under the
“Services” area on the left-hand site of the web-site.
Enter your login information when prompted – it’s the
same as your CCR login.
- Once logged in to the web-site click on “Download
Client” in the upper-right portion of the site. Select
the client installer appropriate for your machine and run it. The
.msi file is the installer for Windows, the .rpm file is the
installer for RedHat linux, and the .dmg file is the installer for
Max OS X.
- Note: this step only needs to be performed once (updated
2014-01-10, a new client is available and will need to be refreshed
to use the updated software).
- Once the viz node client software is installed you can launch a
3D Linux desktop session from the website. Click “Desktop
sessions -> 3D Linux Session” in the
“Services” tab on the left-hand side of the web-site.
Use the “Gnome” Window manager and use the
“Default” screen resolution unless you are confident
that one of the higher resolution alternatives matches your system.
Then click “Start Session”.
- Your browser will prompt you to open the client session, click
"Open" or "OK depending on your browser.
- This software has been tested on Firefox, Internet Explorer and
- A new VNC window will appear containing the desktop, as shown
below. In the “Server Status” dialog click
“Close” to dismiss the 32-bit application warning.
- At this point, you are running on a fully hardware accelerated
OpenGL desktop, and you can run any graphics applications
IMPORTANT : Please close your session from the "Sessions"
tab of the webpage when you are done. We have a limited
number of licenses for the remote visualization
