"!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."

!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." [http://www.paraview.org/in-situ link]

Ok, what do you have to do:
 * check this webpage [http://www.paraview.org/in-situ 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 [http://www.paraview.org/in-situ link])

=== Build !ParaView
!ParaView is prebuild for you. \\
You can find it [https://wci.llnl.gov/simulation/computer-codes/visit/executables here].

Ok, you want to build it myself:

 [wiki:ParaView/build_x86     => ... for general x86] \\
 [wiki:ParaView/build_Jureka  => ... for JUREKA] \\
 [wiki:ParaView/build_Juqueen => ... for JUQUEEN]
