The OverView Informatics Client

What is OverView?

OverView is a generalization of the ParaView scientific visualization application to support the ingestion, processing, and display of informatics data. The ParaView client-server architecture provides a mature framework for performing scalable analysis on distributed memory platforms, and OverView will use these capabilities to analyze informatics problems that are too large for individual workstations.

Why OverView?

Few existing informatics toolkits or applications are written with parallelization in-mind.  OverView is intended to tackle the “next generation” of large informatics problems, using ParaView’s existing support for the world’s largest high performance computing systems. The components in OverView are based on the Titan Toolkit. Titan represents a significant expansion of the Visualization ToolKit (VTK) to support the ingestion, processing, and display of informatics data. By leveraging the VTK engine, Titan provides a flexible, component based, pipeline architecture for the integration and deployment of algorithms in the fields of intelligence, semantic graph and information analysis. For more information on Titan you can visit the Kitware Infovis Wiki.

How do I use it?

Run the OverView client on your Windows, OSX, or Linux workstation.  Whether you analyze your data in-process or on an external supercomputer, OverView provides a consistent pipeline metaphor and graphical user interface, each of which can be extended at runtime using a flexible plugin architecture.

How do I get it?

OverView is part of the ParaView CVS repository. You can build OverView from source just as you would build ParaView; visit the Building OverView page for details on how to get started.

Opportunities for Collaboration

OverView is currently developed and supported by Sandia National Laboratories in collaboration with Kitware Inc.  We are actively-seeking collaboration with universities, laboratories and institutions interested in open source development. Please contact Sandia National Laboratories or Kitware Inc. for more information.

How do I get support?

Send questions, bug reports or feature requests to vtkusers@vtk.org or vtk-developers@vtk.org.

• Someone from the Titan support and development team will get back to you with answers and we will log bugs or feature requests on the vtk bug tracker.
• Announcements are sent out to the vtkusers@vtk.org list so interested users should sign up for that list.
• Sandia employees also have these direct email lists:
  • Help and Support: titan-help@sandia.gov
  • User's List: titan-users@sandia.gov
  • Developer's List: titan-dev@sandia.gov
