Visualization at Jülich Supercomputing Centre

Introduction

The Cross-Sectional Team "Visualization" (CST-Vis) at JSC assists users by developing and adapting software tools for visualization of scientific data to meet their special needs.

The research focus of this team is dedicated to remote Big Data and in-situ visualisation on HPC systems through the application and further development of parallel visualisation packages like VisIt and ParaView. This covers the whole process starting from data generation over data post-processing on large supercomputer systems like JUQUEEN and JURECA up to image rendering and presentation of results, e.g. on display systems of different scales. Among them are a stereoscopic back projection system and a large scale cylindrical 3D display wall.

We belive, that visualization is one of the most important, and commonly used, methods of analyzing and interpreting data from computing simulations.

	The availability of remote visualization, either implemented within visualization applications themselves, or through server software, eliminates the need for off-site file transfers and allows HPC users to run a broad range of visualization tools in-place on the supercomputer where the data resides. more...

VisIt

"VisIt is an Open Source, interactive, scalable, visualization, animation and analysis tool. From Unix, Windows or Mac workstations, users can interactively visualize and analyze data ranging in scale from small (<101 core) desktop-sized projects to large (>105 core) leadership-class computing facility simulation campaigns. Users can quickly generate visualizations, animate them through time, manipulate them with a variety of operators and mathematical expressions, and save the resulting images and animations for presentations. VisIt contains a rich set of visualization features to enable users to view a wide variety of data including scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured, adaptive and unstructured meshes. Owing to its customizeable plugin design, VisIt is capabable of visualizing data from over 120 different scientific data formats." ​https://wci.llnl.gov/simulation/computer-codes/visit more...

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." ​http://www.paraview.org/Wiki/ParaView more...
