In recognition of the Cornell Theory Center’s (CTC) contributions to the global research community since 1985 and its status as a center-of-excellence for Windows-based high-performance computing, the Center will sponsor an Open House on April 20, 2005, from 1:00 p.m. to 6:00 p.m. in Rhodes Hall. Members of the Cornell community and the public are invited to visit at their convenience. During the afternoon, a virtual reality demonstration will be presented in the CAVE (Rhodes Hall, sixth floor); a visualization retrospective slide show will highlight visualizations created since 1987; and demonstrations covering topics ranging from data-intensive computing to bioinformatics, agriculture to virtual science fairs, and fracture mechanics, will also be presented on the sixth floor of Rhodes Hall. Light refreshments will be served. “The event will illustrate that computational science can be intensely fun,” said CTC Executive Director Linda Callahan. “Demonstrations that highlight landmark research accomplished by world renowned Cornell scientists will be featured. In addition, visitors will be able to ‘walk’ on the lunar surface, ‘dance’ inside a molecule, and ‘dive’ inside the crack on a fighter jet’s wing.” One of Cornell’s interdisciplinary research centers and a division of the university’s Faculty of Computing and Information Science, CTC is marking its 20th anniversary with several other upcoming events and celebrations. On May 3, CTC will present two lunch-time presentations. In April, join Dave Lifka, CTC’s chief technical officer, for “Seamless High Performance Computing – Reaching out to New Classes of Users.” In May, Johannes Gehrke, CTC associate director and computer science professor, will present information on data-driven science. These presentations will be held from 11:30 to 1:00 p.m. in 655 Rhodes Hall. In early May, CTC will present “The Art of Computational Science: From Fractals to Functions,” a small display at the Herbert F. Johnson Museum of Art. In the Museum’s lobby, the display will feature two dozen colorful and bold visualizations illustrating research done with CTC resources. The display will be accompanied by a series of educational handouts for students in grades K-12. On May 24, from 9:00 a.m. to 4:00 p.m. in G10 Biotechnology, CTC will sponsor the Symposium on High-Performance Computing: Predictions and Visions for the Future, featuring the following speakers: Kyril Faenov, director of high-performance computing at Microsoft Anthony Ingraffea, Dwight C. Baum professor of engineering, Cornell University Raymond Laflamme, director of the Institute for Quantum Computing, University of Waterloo Jaron Lanier, computer scientist, composer, visual artist, and author David Turek, vice president of Deep Computing at IBM Michael Waterman, professor of biological sciences, University of Southern California
