Das Buch ist eine praktische EinfA1/4hrung in das Hochleistungsrechnen auf Linux-Clustern. In vier Teilen (Grundlagen, Technik, Programmierung, Praxis) wird ausfA1/4hrlich erklArt, wie man einen Haufen (Cluster) preiswerter Standard-PCs in einen Parallelcomputer verwandelt und diesen dann zur LAsung rechenintensiver Probleme einsetzt. Insbesondere enthAlt das Buch eine fundierte EinfA1/4hrung in MPI, dem grundlegenden Programmiermodell fA1/4r Cluster-Computer. Dabei werden anhand konkreter Beispiele die wichtigsten Paradigmen paralleler Programmierung prAsentiert. Vorgestellt werden auAerdem Entwicklungswerkzeuge, die Fehlersuche in parallelen Programmen und nA1/4tzliche Bibliotheken.

Official review of the 1992 Superbike World Championship. Reigning champion Doug Polen was back to renew his fierce rivalry with fellow Ducati rider Raymond Roche, but the pair would be pushed all the way by other Superbike stars including Aaron Slight, Giancarlo Falappa, Rob Phillis and Britain's own Carl Fogarty. The programme features action from all 13 rounds of the championship, covering 26 races in 11 different countries.

In the last decade, the boundary between physics and computer science has become a hotbed of interdisciplinary collaboration. Every passing year shows that physicists and computer scientists have a great deal to say to each other, sharing metaphors, intuitions, and mathematical techniques. In this book, two leading researchers in this area introduce the reader to the fundamental concepts of computational complexity. They go beyond the usual discussion of P, NP and NP-completeness to explain the deep meaning of the P vs. NP question, and explain many recent results which have not yet appeared in any textbook. They then give in-depth explorations of the major interfaces between computer science and physics: phase transitions in NP-complete problems, Monte Carlo algorithms, and quantum computing. The entire book is written in an informal style that gives depth with a minimum of mathematical formalism, exposing the heart of the matter without belabouring technical details. The only mathematical prerequisites are linear algebra, complex numbers, and Fourier analysis (and most chapters can be understood without even these). It can be used as a textbook for graduate students or advanced undergraduates, and will be enjoyed by anyone who is interested in understanding the rapidly changing field of theoretical computer science and its relationship with other sciences.

Triple bill of festive children's features. 'The Flight Before Christmas' (2008), a Finnish animation, follows the adventures of Niko (voice of Andrew McMahon), a young reindeer who learns that his absentee father works for Santa's Flying Reindeer Squad. Unfortunately, however, Niko's inevitable longing to follow in his father's footsteps is hampered by his vertigo. With the help of an accident-prone flying squirrel, Niko manages to overcome his fear, and sets out for the North Pole in the hope of finding his father and joining Santa and his fleet. 'Santa's Little Yelpers' (2012) is centred around Oliver Richmond (Andrew Beckham), a young boy continually let down by his parents, Jessica (Shannon Elizabeth) and Jeff (Jason Brooks), who seem to be too preoccupied with their careers to spend any time with him. As a result, Oliver falls in with the wrong crowd, a gang of ne'er-do-wells who get their thrills breaking into houses. Everything changes when Oliver discovers five golden retriever pups in one of the homes they break into. Realising the pups have been abandoned, Oliver tries to convince his parents to keep them and to help recover the mother they pine for. In 'The Elf That Rescued Christmas' (2011) Satan's evil twin is on the loose and bent on destruction, making the prospects of a merry Christmas seem glum. Can a brave elf stave off the threat and save millions of children from disappointment?
