NICS Leads Scientific Visualization Workshop at Clark Atlanta University

The University of Tennessee’s National Institute for Computational Sciences (NICS) and the Extreme Science and Engineering Discovery Environment (XSEDE) sponsored a Scientific Visualization Workshop on Feb. 21 at the Clark Atlanta University Science Research Center in Atlanta. The host for the event was the Clark Atlanta University Department of Computer and Information Science and the IEEE (the Institute of Electrical and Electronics Engineers) Student Chapter.

Amy Szczepanski of NICS’ Center for Remote Data Analysis and Visualization (RDAV) led the group through an exploration of VisIt software, a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms.

According to the VisIt Web site, with the tool, “Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations.”

Dwayne John of the NICS User Support group provided an introduction to XSEDE, which supports 16 supercomputers and high-end visualization and data-analysis resources across the U.S.; offers digital services that provide users with seamless integration of the National Science Foundation’s (NSF) high-performance-computing (HPC) and data resources; and supplies the expertise necessary to ensure that researchers can make the most of the supercomputers and tools.

XSEDE—a five-year, $121-million project funded by NSF as a replacement of the TeraGrid project—is the most advanced, powerful and robust collection of integrated advanced digital resources and services in the world. It is a single virtual system that scientists can use to interactively share computing resources, data and expertise.

After his formal talk on XSEDE high-performance-computing resources, Dwayne John (left), NICS user consultant, answers a number of questions about research in HPC in general, internship opportunities and XSEDE resources.
