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.

Paria (band)

Paria was an American, experimental metal band formed in 2001 and based in Omaha, Nebraska. They have released one EP on Imagine It Records and two full length albums for Black Market Activities. They went on indefinite hiatus in May 2010.

History

Formation and Misanthropos

Paria formed in the fall of 2001 in Omaha, Nebraska. Initially, the band's style was a lot closer to the nu metal genre, but quickly they switched their style to a mixture of mathcore and grindcore styles. The early stages of the band saw members come and go, but by 2003 a solid lineup materialized and the group began honing their sound. During this time, the band recorded a 2-song EP called The Torn Instances on Imagine It Records.

On the strength of their EP, the band signed to Guy Kozowyk's Black Market Activities in March 2004 and began writing and recording their first full length album. The summer saw the band continue touring around the country, including a stop at the first annual Texas Murder Fest in Houston.Misanthropos was released in November 2004, featuring the band's developed technical and experimental sound.
