Portability flags or changes are those which are necessary for the correct execution of a benchmark. That is, the benchmark will not run or will produce the wrong output without these flags or changes

See bus, power

The value of the primary metric being reported for the benchmark

A vertical pipe in a building

Return Heat Index

The capacity of the room based on the mechanical room equipment capacity. This is the sensible tonnage of the mechanical room for supporting the computer or telecommunications room heat loads

A term typically used to describe electrical panels outside of electrical equipment rooms

A percentage value representing the probability that a piece of equipment or system will be operable throughout its mission duration. Values of 99.9% (three 9s) and higher are common in data and communications equipment areas. For individual components, the reliability is often determined through testing. For assemblies and systems, reliability is often the result of a mathematical evaluation based on the reliability of individual components and any redundancy or diversity that may be employed

The point at which the equipment heat load in the room no longer allows the equipment to run within the specified temperature requirements of the equipment. The load capacity is influenced by many factors. The primary one is the room's theoretical capacity. Other factors, such as the layout of the room and load distribution, also influence the room load capacity
