Using Paraview

Paraview Client (CVMFS)

If you are going to use paraview for light use of result preview, you could login in slurm-ui01 or slurm-ui02 and simply use the prebuilt paraview in our CVMFS system. First, login in slurm-ui:

ssh -XY jack@slurm-ui01.twgrid.org

Note

You must enable both -X and -Y options when using ssh with X11 forwarding. If you just use -X, the xwindow application will not be shown on your local screen.

Then, initialize the paraview module:

module load app/paraview

Then, you could start using paraview by:

paraview

Note

Paraview client is written with QT, for better display effect, you have better to have QT/X11 compatible environment available in your access machine. We recommend you use linux desktop to use the Paraview client in CVMFS. If you have problem open paraview with CVMFS, please use the paraview client in DiCOSApp, see section below.

Paraview Client (DiCOSApp)

You could also use the prebuilt image made by ASGC to use paraview. An xfce4 desktop environment and paraview 5.8.0 are installed in the DiCOSApp. You could just simply launch the paraview DiCOSApp and then use it. Just click the launch button on your DiCOSApp page.

If you would like to use GPU to render your data, please open pvserver DiCOSApp first, and then get the client/server (cs) URL from that DiCOSApp (see next section). Select file → connect to edit a new server, for example:

_images/paraview_cs_1.png

Then click connect botton to connect to the pvserver. the cs pvserver will be prompt in the Pipeline Browser dialog, like:

Then, you could start browsing and viewing your data.

Note

  • If you are using client/server (cs) mode of paraview, you must have identical version of paraview on both side to make a successful connection.

  • The ceph working directories and dicos_ui_home are accessible in the DiCOSApp too

  • Because the image of paraview client is larger, so it may take you a few minutes to start the dicosapp upon the first launch on specific machine. Please be patient for the readiness of the DiCOSApp.

Paraview Server (pvserver)(DiCOSApp)

You could use the pvserver DiCOSApp to open a render/data server with GPU (1 GTX-1080Ti) support. To use it, open pvserver DiCOSApp on the DiCOSApp page.

Note

  • The directory structure for DiCOS users on pvserver is the same to that in dicos-ui and slurm-ui.

  • If you are using client/server (cs) mode of paraview, you must have identical version of paraview on both side to make a successful connection.
