ParaView
ParaView is an open-source, multi-platform data analysis and visualization application. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. The data exploration can be done interactively in 3D or programmatically using ParaView’s batch processing capabilities.
ParaView was developed to analyse extremely large datasets using distributed memory computing resources. It can be run on supercomputers to analyse datasets of petascale size as well as on laptops for smaller data, has become an integral tool in many national laboratories, universities and industry, and has won several awards related to high performance computation.
ParaView ia an open-source, interactive, scalable, data analysis and scientific visualization tools. It can be used to visualize the simulation data or processing the data by using GUI or non-interactive mode by using the Python scripting. Using non-interacting mode, that is using the python scripting is much faster than using the interactive mode, when the data set is larger in both ParaView and VisIt.
Available versions of ParaView in ULHPC¶
To check available versions of ParaView at ULHPC type module spider paraview.
The following list shows the available versions of ParaView in ULHPC.

Interactive mode¶
To open an ParaView in the interactive mode, please follow the following steps:
# From your local computer
$ ssh -X iris-cluster
# Reserve the node for interactive computation
$ salloc -p interactive --time=00:30:00 --ntasks 1 -c 4 --x11 # OR si --x11 [...]
# Load the module abinit and needed environment
$ module purge
$ module load swenv/default-env/latest
$ module load vis/ParaView/5.6.2-intel-2019a-mpi
$ paraview &

Additional information¶
ParaView's User Manual has a detail instructions about visualization and processing data in ParaView. There are two ways of getting or writing the python script for the ParaView:
- Reading the ParaView's python scripting wiki and ParaView's Python Scripting Manual.
- Record the commands that we do in ParaView GUI. Later this commands put into python script and it can be run as python scripting in ParaView.
