Computer performance

Computer performance is characterized by the amount of useful work accomplished by a computer system or computer network compared to the time and resources used. Depending on the context, high computer performance may involve one or more of the following:

Technical and non-technical definitions

The performance of any computer system can be evaluated in measurable, technical terms, using one or more of the metrics listed above. This way the performance can be

Whilst the above definition relates to a scientific, technical approach, the following definition given by Arnold Allen would be useful for a non-technical audience:

Performance (film)

Performance is a 1970 British crime drama film directed by Donald Cammell and Nicolas Roeg, written by Cammell and starring James Fox and Mick Jagger of The Rolling Stones, in his film acting debut. The film was produced in 1968 but not released until 1970.

Plot

Chas (James Fox) is a member of an East London gang led by Harry Flowers (Johnny Shannon); his specialty is intimidation through violence as he collects pay-offs for Flowers. He is very good at his job, and has a reputation for liking it. His sexual liaisons are casual and rough. When Flowers decides to take over a betting shop, owned by Joey Maddocks (Anthony Valentine), he forbids Chas to get involved, as he feels Chas's complicated personal history with Maddocks (which is at least partly gay) may lead to trouble. Chas is angry about this and later humiliates Maddocks, who retaliates by wrecking Chas's apartment and attacking Chas. Chas shoots him, packs a suitcase and runs from the scene.

When Flowers makes it clear that he has no intention of offering protection to Chas but instead wants him eliminated, Chas decides to head for the countryside to hide but instead winds up hiding out in London, requesting that Tony (a trusted friend he refers to as 'Uncle') helps him get out of the country. He assumes a new name, Johnny Dean, and appears at the house of Turner (Mick Jagger), makes a clumsy attempt to ingratiate himself with Pherber (Anita Pallenberg), one of the female inhabitants, and moves in. Turner is a reclusive, eccentric former rock star who has "lost his demon", and who lives there with his female friends Pherber and Lucy (Michele Breton), with whom he enjoys a non-possessive and bisexual ménage à trois, and their child maid Lorraine (Laraine Wickens).

Algorithm

In mathematics and computer science, an algorithm (ⁱ/ˈælɡərɪðəm/ AL-gə-ri-dhəm) is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning.

The words 'algorithm' and 'algorism' come from the name al-Khwārizmī. Al-Khwārizmī (Persian: خوارزمي‎‎, c. 780-850) was a Persian mathematician, astronomer, geographer, and scholar.

An algorithm is an effective method that can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.

Algorithm (C++)

In the C++ Standard Library, algorithms are components that perform algorithmic operations on containers and other sequences.

The C++ standard provides some standard algorithms collected in the <algorithm> standard header. A handful of algorithms are also in the <numeric> header. All algorithms are in the std namespace.

Categories of algorithms

The algorithms in the C++ Standard Library can be organized into the following categories.
