Data & Visualization

Data Management

LC provides users with a variety of powerful and time-conserving ways to access, search, transfer, and archive large-scale scientific data. From custom applications that cater to the specific needs of LC customers to general data management tools useful in any situation, we have you covered. The Data Management Tools Overview contains a list of the various tools available to LC users, along with suggestions for when and where to use them. Among the most heavily used tools is Hopper, a powerful interactive tool that allows users to graphically move, copy, find, delete, and otherwise operate on files. Hopper allows users to connect to and manipulate resources using ftp, ssh, sftp, htar, Endeavor (nft), and other protocols. Other critical tools include a rich set of interfaces to the HPSS archive and an MPI-based suite of tools for efficiently operating on files in Lustre.


The visualization team develops and supports tools for visualizing and presenting scientific data generated by users of the LC high-performance computing Center. Team members are experienced in the use of graphics libraries and environments ranging from "turn-key" tools (e.g. EnSight, AVS, Tecplot, VisIt) to visualization libraries (e.g., IDL and OpenGL) to utilities such as plotting packages and image conversion programs. See +- for a complete listing of supported graphics software. This includes information about each of the products, how to set up your environment to run the software, documentation pointers, and information on installing a local copy of the software if applicable.


  • Consulting on scientific visualization issues (demos, classes, getting started, visualization advice)
  • Troubleshooting graphics-related problems
  • Maintaining a graphics environment, including software, that is current and consistent across LC computing platforms


  • Creating scientific visualizations using a variety of commercial tools
  • Developing customized visualization applications for end users
  • Providing domain-specific visualization techniques

PowerWall Facilities

PowerWalls are multi-projector displays that are both physically large and very high in resolution. The ASC program built and maintains four PowerWall facilities. Two of these are part of the Secure Computing Facility (SCF). The two unclassified PowerWalls are located in the Building 453 Armadillo Room and the Building 451 White Room. The PowerWalls are used for demonstrations at high-level reviews, press conferences, and visits. They may also be used by scientists who wish to show their visualizations on a high-resolution display. The "streaming movie (sm)" format is used to create streaming movies that take advantage of the high resolution of the PowerWalls. Blockbuster is used to play high-resolution movies efficiently on cluster displays. For conversion utilities, see sm tools.
