SPECvirt
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. The SPECvirt_sc2010 benchmark measures the maximum number of workloads that a platform can simultaneously run while maintaining specific quality of service metrics. Each workload, called a tile, consists of a specific set of virtual machines. In addition to generating results that show performance, the benchmark can also be used to generate performance per watt results. The SPECvirt_sc2010 was not supported by SPEC from February 26, 2014 and its successor is SPECvirt_sc2013.

Standard Performance Evaluation Corporation
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. SPEC was founded in 1988. SPEC benchmarks are widely used to evaluate the performance of computer systems; the test results are published on the SPEC website. SPEC evolved into an umbrella organization encompassing four diverse groups; Graphics and Workstation Performance Group (GWPG), the High Performance Group (HPG), the Open Systems Group (OSG) and the newest, the Research Group (RG). Structure * The Open Systems Group (OSG) * The High-Performance Group (HPG) * The Graphics and Workstation Performance Group (GWPG) * SPEC Research Group (RG) Membership Membership in SPEC is open to any interested company or entity that is willing to commit to SPEC's standards. It allows: * Participation in benchmark development * Participation in review of results * Complimentar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Benchmark
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. The term ''benchmark'' is also commonly utilized for the purposes of elaborately designed benchmarking programs themselves. Benchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a CPU, but there are circumstances when the technique is also applicable to software. Software benchmarks are, for example, run against compilers or database management systems (DBMS). Benchmarks provide a method of comparing the performance of various subsystems across different chip/system architectures. Purpose As computer architecture advanced, it became more difficult to compare the performance of various computer systems simply by looking at their specific ...

Server Computer
In computing, a server is a piece of computer hardware or software ( computer program) that provides functionality for other programs or devices, called " clients". This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowle ...

Virtualization
In computing, virtualization or virtualisation (sometimes abbreviated v12n, a numeronym) is the act of creating a virtual (rather than actual) version of something at the same abstraction level, including virtual computer hardware platforms, storage devices, and computer network resources. Virtualization began in the 1960s, as a method of logically dividing the system resources provided by mainframe computers between different applications. An early and successful example is IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. Since then, the meaning of the term has broadened. Hardware virtualization ''Hardware virtualization'' or ''platform virtualization'' refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the underlying hardware resources. For example, a computer that is running Arch Linux may host a virtual mach ...

Performance Per Watt
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. System designers building parallel computers, such as Google's hardware, pick CPUs based on their performance per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself. Spaceflight computers have hard limits on the maximum power available and also have hard requirements on minimum real-time performance. A ratio of processing speed to required electrical power is more useful than raw processing speed. D. J. Shirl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VMmark
VMmark is a freeware virtual machine benchmark software suite from VMware, Inc. The suite measures the performance of virtualized servers while running under load on a set of physical hardware. VMmark was independently developed by VMware. Technical overview In order to measure the efficiency of the virtualization layer - the hypervisor - the suite must run several virtual machines (VMs) simultaneously. Each VM is configured according to a template, three of which are provided with the VMmark software. The templates mimic typical software applications found in corporate data centers, such as email servers, database servers, and Web servers. The VMmark software collects performance statistics that are relevant to each type of application, such as commits per second for database servers, or page accesses per second for web servers. VMs are grouped into logical units called "tiles". When evaluating a system's performance, the VMmark software first calculates a score for each ti ...
