The Cornell Theory Center (CTC) is "a high-performance computing and interdisciplinary research center." Projects conducted at the center have a wide range of topics, but the common focus of each is how sophisticated computer systems can analyze and classify data to solve problems. The CTC Web site has extensive information about its five main research programs, and there are several papers and publications scattered throughout the site. A particular source of pride for the center is its Advanced Cluster Computing Consortium, which operates a computer system that was recently ranked as one of the 500 most powerful computers in the world.
