ParaView
"ParaView is an open-source, multi-platform application designed to visualize data sets of varying sizes from small to very large. The goals of the ParaView project include developing an open-source, multi-platform visualization application that supports distributed computational models to process large data sets. It has an open, flexible, and intuitive user interface. Furthermore, ParaView is built on an extensible architecture based on open standards.
ParaView runs on distributed and shared memory parallel as well as single processor systems and has been successfully tested on Windows, Linux, Mac OS X, IBM Blue Gene, Cray XT3 and various Unix workstations and clusters. Under the hood, ParaView uses the Visualization Toolkit as the data processing and rendering engine and has a user interface written using the Qt cross-platform application framework." link

Run ParaView
We recommend to use ParaView on JURECA via VNC:
There are other more advanced configurations that can be used for Remote Visualization or separation of services (Data, Rendering, and User Interface). Each mode separates the three main components (User Interface, Computation, Rendering) in different ways. More details on possible ParaView scenarios can be found here.
Build ParaView
Please check the prebuild ParaView before you build your own ParaView.
If anything is missing in the prebuild ParaView let us know.
You can find ParaView
- as an desktop icon via VNC (profile 'vis').
- on JURECA as a module (
module spider ParaView
)
If you want to have your own ParaView you can
- download a prebuild ParaView from the official webpage download.
- build ParaView yourself - check the details of the JURECA build.
Parallel ParaView
Parallel Data Management
Data must be distributed across parallel processes to take advantage of resources
- Some ParaView readers import in parallel
- Explicit parallel formats use separate files for partitions (.pvti, global.silo)
- Implicit parallel formats – parallel processes figure out what they need – (.vti, brick-f-values)
- Some ParaView readers may seem to import in parallel
- Actually, import serially and then distribute
- Bad bad bad – 1 process needs enough memory for entire dataset plus additional space for partitioning
- Some ParaView readers do NOT read in parallel
- ... and leave it to you (D3 filter in Paraview)
- See Bad bad bad above
Test Parallel Data Mangement
- Click Sources->Sphere
- Max out Theta Resolution and Phi Resolution
- Click Filters->Alphabetical->Process Id Scalars
- => Segments are colored by which process handles them
In-Situ Visulalization with ParaView Catalyst
ParaView provides a library for in-situ visualization and analysis that is called Catalyst.
"Catalyst is a light-weight version of the ParaView server library that is designed to be directly embedded into parallel simulation codes to perform in situ analysis at run time." link
Ok, what do you have to do:
- check this webpage html
- instrument your code
- link your code with Catalyst
- start simulation
- connect with GUI to simulation
(more detailed infos will be added - in the mean time check this link)
