Running VisIt

VisIt has been installed in the directory /opt/gridware/non-supported/VisIt. Please refer to the VisIt web site for instructions on using VisIt. For interactive graphics, an OpenGL-enabled environment will be required, therefore refer to the page on Remote Visualization for instructions on setting up a connection to the visualization node, and running VisIt with the VirtualGL wrapper. VisIt is an extremely versatile post-processor, and can be used as the primary visualization tool for a very wide range of applications and file formats.

When running VisIt on the visualization node viz01, please note that there appears to be an incompatibility between VisIt and the default gnome-session window manager used by TurboVNC. The work-around for this involves rather using the far more primitive TWM window manager, which happens to be used by the default VNC server. The process to be followed is therefore to initiate a VNC server session using the default VNC server, which should generate an appropriate .vnc/xstartup file which can then be copied to .vnc/xstartup.turbovnc. Kill the VNC server session, then start a TurboVNC server, and it should start up with an old-fashioned looking interface, which is compatible with VisIt. To summarise:

  1. start a system VNCserver
  2. stop the system VNCserver
  3. start a TurboVNC server
  4. stop the TurboVNC server
  5. cp .vnc/xstartup .vnc/xstartup.turbovnc
  6. start a TurboVNC server
  7. connect to it with a TurboVNC client
  8. vglrun visit
