PITAC Report Summary (June 2005): 7“Computational science -- the use of advanced computing capabilities to understand and solve complex problems -- is critical to scientific leadership, economic competitiveness, and national security. It is one of the most important technical fields of the 21st century because it is essential to advances throughout society.”“Universities must significantly change organizational structures: multidisciplinary & collaborative research are needed [for US] to remain competitive in global science”Complex problems: Innovations will occur at boundaries

Louisiana Response: Center for Computation & Technology (CCT)8State commitment for IT in 2002$25M/year for Vision 20/20, $9M to LSUUniversity commitment to build new programsOpportunity to build new world class program in interdisciplinary research & educationEd Seidel recruited to LSU, created & implemented vision for state-wide collaborationCenter for Computation & Technology (2003)Louisiana Optical Network Initiative (2005)CyberTools (2007), LONI Institute (2007)Multidisciplinary Hiring Initiatives (2007)

CCT Plan: Designing a Computational Science Initiative at LSUCyberinfrastructure: access to local/national compute, storage, network, visualization resources; support; end-to-end integration. Interdisciplinary research: university policies on joint appointments, university-wide curricula, appreciation of computational science outcomes (e.g. software, data)Computational research: faculty who develop or use computation as part of their research; undergraduate and graduate courses to train and educate students10CCT Strategic PlanMission: The CCT at LSU is an innovative and interdisciplinary research environment, advancing computational sciences, technologies, and the disciplines they touch. The CCT serves Louisiana through international collaboration, leading progress through revolutionary advancement in academia and industry.Strategic Plan:ResearchEducationServiceInfrastructureEconomic Developmenthttps://cct.lsu.edu/uploads/CCTStrategicPlan20062010.pdf
