For small interactive visualizations, you can use Graham's VDI nodes. Unlike client-server visualizations, on the VDI nodes you'll be using VNC remote desktop. Here are the steps:
For small interactive visualizations requiring upto 256GB memory and 16cores, you can use Graham's VDI nodes. Unlike client-server visualizations, on the VDI nodes you'll be using VNC remote desktop. Here are the steps:


1. Connect to the VDI node of Graham.
1. Connect to gra-vdi as described [https://docs.computecanada.ca/wiki/VNC#VDI_Nodes TigerVNC]


You need to use a [[VNC]] client (Tiger VNC is preferred) to get connected to the VDI node.
2. Open a terminal window and run the following commands:


2. Load CC modules and launch ParaView.
module load CcEnv StdEnv
 
module load paraview/5.5.2
After login to the VDI node, you need to open a terminal in which you issue the following commands
paraview
{{Commands|prompt=[name@server]$
|module load CcEnv StdEnv
|module load paraview/5.5.2
|paraview
}}

For large-scale and automated visualization, we strongly recommend switching from interactive client-server to off-screen batch visualization. ParaView supports Python scripting, so you can script your workflow and submit it as a regular, possibly parallel production job on a cluster. If you need any help with this, please contact [[Technical support]].
