Conference Registration is Open! The third annual TeraGrid conference, being held June 9-13 in Las Vegas, Nevada, will provide the scientific community with opportunities for collaboration and technology sharing to enable scientific discovery using the TeraGrid. Conference registration is open! Please register at: www.tacc.utexas.edu/tg08/index.php?m_b_c=registration. The TeraGrid is a comprehensive cyberinfrastructure enabling world-class open computational research. TeraGrid ’08 will showcase the capabilities, achievements, and impact of TeraGrid in research and education through presented papers, demonstrations, posters, and visualizations. TG08 will foster collaborations among leading researchers, developers, and educators that build on the growing TeraGrid infrastructure. TG08 will also provide information and training to enable both current and future users to achieve optimal results and maximum impact using TeraGrid resources and services. Attendees will include researchers, developers, faculty, and postdocs; graduate students, undergraduate students, and high school teachers; program managers, directors, and liaisons from federal agencies; representatives of companies who use or develop advanced computing technologies; and staff from the TeraGrid partner institutions. Proposals for papers on original, innovative work will be received and reviewed in three tracks: Science, Technology, and Education. The complete “Call for Participation” is available via download at: www.tacc.utexas.edu/tg08/index.php?m_b_c=callForParticipation. In addition, TG08 will recognize outstanding achievements through four new computational challenges: • Capability Computing Challenge: Science Track papers may request to be considered for the TeraGrid Capability Award, which will recognize the scientific application making efficient and justifiable use of the greatest computational power. All scientific applications that utilize at least 5000 processing cores concurrently will be recognized with a TeraGrid 5K Club certificate. • Transformational Science Challenge: Science Track papers that utilize the distributed TeraGrid infrastructure and software technologies in innovative ways to achieve breakthrough scientific results may request to be considered for the TeraGrid Transformational Science Award. • Performance Challenge: Technology Track papers that achieve new levels of performance in any dimension of value to TeraGrid users (WAN bandwidth, file transfer performance, visualization display size, etc.) may request to be considered for the TeraGrid Performance Award. • Student Computing Challenge: The Education track will sponsor a Student Computing Competition to encourage and acknowledge students who are using TeraGrid resources for school-related projects. Final instructions for the papers and challenges, as well as templates for paper submissions, will be made available by March 7. Submissions competing in the TG08 Challenges will be allowed to submit final data and arguments by May 30.
