Managing world-class supercomputing centers

The High Performance Computing (HPC) Division supports the Laboratory mission by managing world-class Supercomputing Centers.

This includes specifying, operating, and assisting in the use of both open and secure high performance computing, storage and emerging data-intensive information science production systems for multiple programs.


HPC Division translates evolving HPC technologies into the assets deployed in our data centers.  This unprecedented-scale computing capability provides solutions to complex problems of strategic national interest.  Our activities span repeated lifetimes of supercomputing systems and infrastructure:

Defining Future Environments

  • Communication and collaborations with industry and academia to follow and shape future supercomputing technology
  • Consultative design and deployment of facility infrastructure supporting future supercomputing
  • HPC-specific system software R&D
  • Testbed explorations of new computing and infrastructure technologies
  • Specifying and assisting in the procurement of small scale to large scale acquisitions
  • Stewardship of programmatic resources via program and project management
  • Integration of computing and supporting infrastructure technology into a fully operational supercomputing environment

Providing Current Capability

  • Scientific Software Engineering services provided to the broader Laboratory
  • Hardware monitoring and maintenance
  • System software monitoring and maintenance
  • Operation and expert support of computing, interconnects, networks, and storage
  • HPC-specific facility and environmental operations
  • Direct user support
