On the TeraGrid, what was Twister?

Note: After ten years of service to the national science and engineering community, the TeraGrid project has ended. It is succeeded by a new National Science Foundation (NSF) program, the Extreme Science and Engineering Discovery Environment (XSEDE). You should move any data stored on TeraGrid systems to an alternate storage resource. If you have leftover service units on your TeraGrid allocation, or if your research requires further use of high performance computational, visualization, storage, and network resources, consider applying for an allocation on one or more XSEDE digital services.

On the TeraGrid, Twister was the data analysis and visualization resource coupled to Frost (NCAR); both systems were retired from TeraGrid service July 31, 2011. For more, see Data analysis and visualization resources in the Frost user guide.
