Computing and Computational Sciences Directorate

Advancing computing and data capabilities for scientific discovery and continued U.S. technological leadership

The Computing and Computational Sciences Directorate (CCSD) oversees Oak Ridge National Laboratory’s (ORNL’s) immense store of computing power and its talented staff of computational scientists and mathematicians, conducting state-of-the-art research and development in support of DOE's missions and programs.

The directorate houses the Oak Ridge Leadership Computing Facility (OLCF), home to the nation's most powerful supercomputer, Summit. In 2018, ORNL delivered Summit to advance leadership-class computing for open science. Summit enables us to address, with greater complexity and higher fidelity, questions concerning who we are, as well as our place on earth and in our universe. The OLCF will also be home to Frontier, ORNL’s upcoming exascale supercomputer scheduled for delivery in 2021.

CCSD contains the institutional knowledge needed to transform basic science into cutting-edge energy and security applications critical to national interests. Our organization is committed to research and development in the data sciences, including the modeling, simulation, and analysis of rapidly growing data sources. The directorate  is also a premier source for high-performance computing, applied mathematics, quantum information science, and artificial intelligence research.
