The High Performance Computing Operations (HPC Ops) Group keeps the OLCF leadership supercomputing systems running. Members of the group monitor all systems 24 hours a day, seven days a week, 365 days a year, and are responsible for administration, configuration management, and cybersecurity. The staff works with infrastructure systems, with Titan, scratch and archival storage, and with other OLCF supercomputers. The HPC Ops tests the systems when they are installed and upgraded, and use diagnostic tools to continually monitor them. They anticipate problems before they arise and identify components that are near failure. The group also ensures that all systems conform to ORNL cybersecurity policy.
