A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, there have existed supercomputers which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS).
The Standard Performance Evaluation Corporation (SPEC) is an American non-profit corporation that aims to "produce, establish, maintain and endorse a standardized set" of performance benchmarks for computers.
Load testing is the process of putting demand on a system and measuring its response.
Energy Star is a program run by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) that promotes energy efficiency. The program provides information on the energy consumption of products and devices using different standardized methods. The Energy Star label is found on more than 75 different certified product categories, homes, commercial buildings, and industrial plants. In the United States, the Energy Star label is also shown on the Energy Guide appliance label of qualifying products.
A data center or data centre is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems.
Green computing, green IT, or ICT sustainability, is the study and practice of environmentally sustainable computing or IT.
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
SPECint is a computer benchmark specification for CPU integer processing power. It is maintained by the Standard Performance Evaluation Corporation (SPEC). SPECint is the integer performance testing component of the SPEC test suite. The first SPEC test suite, CPU92, was announced in 1992. It was followed by CPU95, CPU2000, and CPU2006. The latest standard is SPEC CPU 2017 and consists of SPECspeed and SPECrate.
Evaluation is the process of judging something or someone based on a set of standards.
Building performance is an attribute of a building that expresses how well that building carries out its functions. It may also relate to the performance of the building construction process. Categories of building performance are quality, resource saving and workload capacity. The performance of a building depends on the response of the building to an external load or shock. Building performance plays an important role in architecture, building services engineering, building regulation, architectural engineering and construction management. Prominent building performance aspects are energy efficiency, thermal comfort, indoor air quality and daylighting.
80 Plus is a voluntary certification program launched in 2004, intended to promote efficient energy use in computer power supply units (PSUs).
In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. This rate is typically measured by performance on the LINPACK benchmark when trying to compare between computing systems: an example using this is the Green500 list of supercomputers. Performance per watt has been suggested to be a more sustainable measure of computing than Moore’s Law.
Central Power Research Institute (CPRI) was established by the Government of India in 1960 with headquarters in Bangalore. The Institute was re-organized into an autonomous Society in the year 1978 under the aegis of the Ministry of Power, Government of India. The main objective of setting up the Institute is to serve as a national Level laboratory for undertaking applied research in electrical power engineering besides functioning as an independent national testing and certification authority for electrical equipment and components to ensure reliability in power systems and to innovate and develop new products.
Bluetooth Low Energy is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries. It is independent of classic Bluetooth and has no compatibility, but Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and LE can coexist. The original specification was developed by Nokia in 2006 under the name Wibree, which was integrated into Bluetooth 4.0 in December 2009 as Bluetooth Low Energy.
IT energy management or Green IT is the analysis and management of energy demand within the Information Technology department in any organization. IT energy demand accounts for approximately 2% of global CO2 emissions, approximately the same level as aviation, and represents over 10% of all the global energy consumption. IT can account for 25% of a modern office building's energy cost.
In computer networking, Energy-Efficient Ethernet (EEE) is a set of enhancements to twisted-pair, twinaxial, backplane, and optical fiber Ethernet physical-layer variants that reduce power consumption during periods of low data activity. The intention is to reduce power consumption by 50% or more, while retaining full compatibility with existing equipment.
SPECvirt_sc2010 is a computer benchmark that evaluates the performance of a server computer for virtualization. It is available from the Standard Performance Evaluation Corporation (SPEC). It was introduced in July, 2010.
Electronic systems’ power consumption has been a real challenge for Hardware and Software designers as well as users especially in portable devices like cell phones and laptop computers. Power consumption also has been an issue for many industries that use computer systems heavily such as Internet service providers using servers or companies with many employees using computers and other computational devices. Many different approaches have been discovered by researchers to estimate power consumption efficiently. This survey paper focuses on the different methods where power consumption can be estimated or measured in real-time.
The SNIA Emerald Program Power Efficiency Measurement Specification, is a storage specification developed and maintained by the Storage Networking Industry Association (SNIA) and cross-referenced by the Environmental Protection Agency’s EnergyStar program. The specification consists of a storage types taxonomy, system under test workload and energy measurement method, measured metrics for active and idle operational states, and presence tests for capacity optimization technologies. The measured metric data is generated through the use of well-defined standard testing and data reduction procedures prescribed in the SNIA Emerald Specification.
Solmetric Corporation, based in Sebastopol, California, is a manufacturer of solar test and measurement equipment and developer of solar design software. It was founded in 2005 and is best known for its shade measurement tool, the SunEye, and its I-V curve tracer, the PV Analyzer. The award-winning SunEye shade tool is used primarily by residential solar installers. It tells the user when and where shadows will fall so that solar modules can be placed to maximize energy harvest. The PV Analyzer is an I-V curve tracer. It is used for commissioning and troubleshooting commercial and utility scale PV systems.
