Thrashing (computer science)

In computer science, thrashing occurs when a computer's virtual memory subsystem is in a constant state of paging, rapidly exchanging data in memory for data on disk, to the exclusion of most application-level processing. This causes the performance of the computer to degrade or collapse. The situation may continue indefinitely until the underlying cause is addressed. The term is also used for various similar phenomena, particularly movement between other levels of the memory hierarchy, where a process progresses slowly because significant time is being spent acquiring resources.

Overview

If a process does not have enough pages, thrashing is a high paging activity, and the page fault rate is high. This leads to low CPU utilization. In modern computers, thrashing may occur in the paging system (if there is not sufficient physical memory or the disk access time is overly long), or in the communications system (especially in conflicts over internal bus access), etc. Depending on the configuration and algorithms involved, the throughput and latency of a system may degrade by multiple orders of magnitude. Thrashing is a state in which the CPU performs 'productive' work less and 'swapping' more. The CPU is busy in swapping pages, so much that it can not respond to users' programs as much as required. Thrashing occurs when there are too many pages in memory, and each page refers to another page. The real memory shortens in capacity to have all the pages in it, so it uses 'virtual memory'. When each page in execution demands that page that is not currently in real memory (RAM) it places some pages on virtual memory and adjusts the required page on RAM. If the CPU is too busy in doing this task, thrashing occurs.

Thrash metal

Thrash metal is an extreme subgenre of heavy metal music characterized by its fast tempo and overall aggression. The songs usually use fast percussive beats and low-register guitar riffs, overlaid with shredding-style lead work. The lyrics often deal with social issues and reproach for The Establishment, using direct and denunciatory language, an approach which partially overlaps with the hardcore genre.

The genre evolved in the early 1980s from combining the fast drum beats and attitude of hardcore punk with the double bass drumming, heavy and complex guitar style of the New Wave of British Heavy Metal (NWOBHM). It emerged partially as a reaction to the more conventional and widely acceptable glam metal, a less aggressive, pop music-infused heavy metal subgenre which appeared simultaneously. Thrash metal was an inspiration for subsequent extreme genres such as death metal and black metal.

Four American bands, Anthrax, Megadeth, Metallica, and Slayer, are credited with pioneering and popularizing the genre. The Clash of the Titans tour (1990–1991), which featured Megadeth, Slayer, and Anthrax, is considered the genre's pinnacle, after which thrash metal saw a decline in popularity throughout the decade. Thrash metal has seen a resurgence in recent times, with many of the older bands returning to their roots with their new releases. A new generation of thrash metal bands emerged in the early 2000s, drawing lyrical and visual inspiration from the older groups.

MDK (series)

MDK is a third-person shooter video game series. MDK is a series of three games (two separate games and a re-make of the second) which place the player in the control of Kurt Hectic, a janitor on Doctor Hawkins's ship, the "Jim Dandy". In each game, the Earth is under attack by "Streamriders", aliens who ride energy streams to the earth's surface in order to take over the planet. The Streamriders' purpose is to strip the earth of its minerals and resources. In the first game, Kurt is the only playable character, but in the second game, you gain the opportunity to play as him, Doctor Hawkins, and his genetically-engineered pet dog, Bones (often called "Max").

Games

MDK

The game tells the story of its protagonist, Kurt Hectic, and his attempts to rescue Earth from an alien invasion of gigantic strip mining city-vehicles named 'Minecrawlers' that are not only removing all of Earth's natural resources but are also flattening any people and cities that get in their way. The game combines action with a sense of humour.

MDK (video game)

MDK is a 1997 third-person shooter video game developed by Shiny Entertainment for Microsoft Windows. It was ported to the Mac by Shokwave, and to the PlayStation by Neversoft. It was published on all systems by PIE in North America and Interplay Entertainment in Europe. The Windows version was released in April 1997, the Mac version in June and the PlayStation version in November. The game was released on GOG.com in September 2008, and on Steam in September 2009.

The game tells the story of Kurt Hectic, a janitor who reluctantly must attempt to save Earth from an alien invasion of gigantic strip mining city-size vehicles named "Minecrawlers". These Minecrawlers are not only removing all of earth's natural resources, but are also crushing any people and cities that get in their way. Aided by his boss, the (possibly) insane inventor/scientist Dr. Fluke Hawkins, and a genetically engineered robotic two-legged/four-armed dog named Bones (although he prefers Max), Kurt must infiltrate each Minecrawler, and fight his way to the pilot, whom he must then kill before returning to Hawkins' in-orbit space station, the Jim Dandy.
