TL;DR: VPIC has enabled previously intractable simulations in numerous areas of plasma physics, including magnetic reconnection and laser plasma interactions; next generation supercomputers like Roadrunner will enable further advances.
Abstract: The algorithms, implementation details, and applications of VPIC, a state-of-the-art first principles 3D electromagnetic relativistic kinetic particle-in-cell code, are discussed. Unlike most codes, VPIC is designed to minimize data motion, as, due to physical limitations (including the speed of light!), moving data between and even within modern microprocessors is more time consuming than performing computations. As a result, VPIC has achieved unprecedented levels of performance. For example, VPIC can perform ∼0.17 billion cold particles pushed and charge conserving accumulated per second per processor on IBM’s Cell microprocessor—equivalent to sustaining Los Alamos’s planned Roadrunner supercomputer at ∼0.56 petaflop (quadrillion floating point operations per second). VPIC has enabled previously intractable simulations in numerous areas of plasma physics, including magnetic reconnection and laser plasma interactions; next generation supercomputers like Roadrunner will enable further advances.

TL;DR: In this paper, a 3D electromagnetic charge-conserving relativistic kinetic particle-in-cell code was adapted to run on Los Alamos's Roadrunner, the first supercomputer to break a petaflop (1015 floating point operations per second) in the TOP500 supercomputer performance rankings.
Abstract: VPIC [1], a first-principles 3d electromagnetic charge-conserving relativistic kinetic particle-in-cell code, was recently adapted to run on Los Alamos's Roadrunner [2], the first supercomputer to break a petaflop (1015 floating point operations per second) in the TOP500 supercomputer performance rankings. [3] We summarize VPIC's modeling capabilities, VPIC's optimization techniques and Roadrunner's computational characteristics. We then discuss three applications enabled by VPIC's unprecedented performance on Roadrunner: modeling laser plasma interaction in upcoming inertial confinement fusion experiments at the National Ignition Facility, modeling short-pulse laser GeV ion acceleration and modeling reconnection in space and laboratory plasmas.
TL;DR: Neale and Krutnik as mentioned in this paper argue that all forms and modes of the comic involve deviations from aesthetic and cultural conventions and norms, and, to demonstrate this, they discuss a wide range of programmes and films.
Abstract: Steve Neale and Frank Krutnik take as their starting point the remarkable diversity of comedy's forms and modes - feature-length narratives, sketches and shorts, sit-com and variety, slapstick and romance. Relating this diversity to the variety of comedy's basic conventions - from happy endings to the presence of gags and the involvement of humour and laughter - they seek both to explain the nature of these forms and conventions and to relate them to their institutional contexts. They propose that all forms and modes of the comic involve deviations from aesthetic and cultural conventions and norms, and, to demonstrate this, they discuss a wide range of programmes and films, from Blackadder to Bringing up Baby, from City Limits to Blind Date, from the Roadrunner cartoons to Bless this House and The Two Ronnies. Comedies looked at in particular detail include: the classic slapstick films of Keaton, Lloyd, and Chaplin; Hollywood's 'screwball' comedies of the 1930s and 1940s; Monty Python, Hancock, and Steptoe and Son. The authors also relate their discussion to radio comedy.
TL;DR: Turchi as mentioned in this paper traces the history of maps, from their initial decorative and religious purposes to their later instructional applications, and explores how writers and cartographers use many of the same devices for plotting and executing their work, making crucial decisions about what to include and what to leave out, in order to get us from here to there, without excess baggage or a confusing surplus of information.
Abstract: This book tells us how maps help us to understand where we are in the world in the same way that literature, whether realistic or experimental, attempts to explain our realities. "Maps of the Imagination" explores how writers and cartographers use many of the same devices for plotting and executing their work, making crucial decisions about what to include and what to leave out, in order to get us from here to there, without excess baggage or a confusing surplus of information.Turchi traces the history of maps, from their initial decorative and religious purposes to their later instructional applications. He describes how maps rely on projections in order to portray a three-dimensional world on the two-dimensional flat surface of paper, which he goes on to relate to what writers do in projecting a literary work from the imagination onto the page.Drawing from texts as varied as poetry by Louise Gluck, stories by Kate Chopin and Robert Coover, novels by Robert Louis Stevenson and Italo Calvino, the film "Memento", and Chuck Jones' "Roadrunner" cartoons, Turchi ranges across a wide literary geography, illustrating his argument with an array of maps and illustrations, which will be scattered throughout the text.
