Innovative Computing Laboratory

ICL is a world leader in enabling technologies and software for scientific computing. Our vision is to provide high-performance tools to tackle science’s most challenging problems and to play a major role in the development of standards for scientific computing in general. Successful research efforts have provided the foundation for addressing the challenges of the future. Recognizing that enabling technologies serve as catalysts for computational innovation, ICL continues to adapt to the ever increasing computational demands of the scientific community through our vision of what the next generation of enabling technologies can accomplish. Current projects are broken down into four main focus areas: numerical libraries, high performance distributed computing, performance evaluation and benchmarking, and asset management.

Joint Institute for Computational Sciences

UT and ORNL co-established JICS to advance scientific discovery and state-of-the-art engineering in order to further knowledge of computational modeling and simulation by 1) taking full advantage of the terascale (and beyond) computers in the National Center for Computational Sciences housed at ORNL, and 2) educating a new generation of scientists and engineers well-versed in the application of computational modeling and simulation for solving for the most challenging scientific and engineering problems.
