Appendix H

Glossary

Availability: The availability level of a computer, component, or device is a percentage figure determined by dividing the operational use time by the difference between wallclock and null time.

Computer: A computational platform that shares a high-speed interconnect (largest useful MPI program).

Physical Core: A physical core is the basic hardware unit capable of running one or more program context(s), maintaining the correct program state, registers and execution order as it executes operations through the floating point and arithmetic logic units.

Downtime: That period of time when all of an HPCS component’s workload cannot be accomplished due to a malfunction in the Contractor-maintained HPCS hardware or software, or when the HPCS or a component of the HPCS is released to the Contractor for maintenance.

HPCS: A high performance computing system can be one large system or an aggregation of subsystems. A given system/subsystem can be further described by individual components. A single component may span multiple subsystems (e.g. a cluster file system shared across multiple computers).

Integrated Management Team: Government personnel responsible for the successful integrated management of the following HPC functions: Acquisition Management, Resource Management, Architecture Management, Long Term Planning, External HPC Collaboration Management and for HPC monitoring and reporting activities.

Null Time: The period of time when the workload cannot be accomplished due to environmental failure at a Government furnished site, such as loss of electric power or cooling, or recovery from environmental failure.

Site Lead: Government manager of NOAA HPC site.

Subsystem: The set of components which comprise a HPCS.
