CISL staff contributed two tutorials and a technology presentation at the TeraGrid '09 conference in Arlington, Virginia on 22-29 June 2009. The conference hosted 465 participants and showcased the capabilities, achievements, and impact of the TeraGrid in research and education. Tutorial sessions on the first day provided hands-on training to enable users of TeraGrid resources to achieve maximum impact. Conference sessions were organized into three tracks: technology, science, and education/outreach/training. The TeraGrid '09 website provides links to abstracts, papers, and viewgraphs from all the sessions.

Terascale Remote and Collaborative Visualization

John Clyne and Mary Haley (not pictured) of NCAR's Computational and Information Systems Laboratory (CISL) teamed with Kelly Gaither (Texas Advanced Computing Center) and Joseph Insley (University of Chicago) to present tutorials in the "Terascale Remote and Collaborative Visualization" session on the first day of the conference. Participants received an overview of scientific visualization principles, remote and collaborative visualization capabilities, and a detailed look at how remote and collaborative visualization is facilitated on the TeraGrid. The presenters provided introductory training on many of these visualization tools, including VisIt, ParaView, NCL, and VAPOR. Mary Haley led the NCAR Command Language (NCL) tutorial, and John Clyne described the Visualization and Analysis Platform for Ocean, Atmosphere, and Solar Researchers (VAPOR).

The Asteroseismic Modeling Portal

Matthew Woitaszek (CISL) presented an introduction to the Asteroseismic Modeling Portal (AMP), which was designed as a science gateway specifically for the TeraGrid. AMP provides a web-based interface for astronomers to derive the properties of Sun-like stars from observations of their pulsation frequencies. Offering an asteroseismology model to a broad international community of researchers, AMP facilitates automatic model execution, simplifies data sharing among research groups, and helps researchers produce uniform analyses of asteroseismic data for stars of interest. Speaking for the AMP development team that included Travis Metcalfe (NCAR High Altitude Observatory) and Ian Shorrock (CISL), Matthew Woitaszek described the science, the observations provided by the Kepler satellite mission, and the workflow required of the gateway. He concluded by summarizing AMP design, development, and deployment. Materials from this presentation are on the web at
