Tools for High Performance Computing 2014

www.ebooks.com/cj.asp?IID=2094472&cjsku=2094472...
Numerical simulation and modelling using High Performance Computing has evolved into an established technique in academic and industrial research. At the same time, the High Performance Computing infrastructure is becoming ever more complex. For instance, most of the current top systems around the world use thousands of nodes in which classical CPUs are combined with accelerator cards in order to enhance their compute power and energy efficiency. This complexity can only be mastered with adequate development and optimization tools. Key topics addressed by these tools include parallelization on heterogeneous systems, performance optimization for CPUs and accelerators, debugging of increasingly complex scientific applications and optimization of energy usage in the spirit of green IT. This book represents the proceedings of the 8 th International Parallel Tools Workshop, held October 1-2, 2014 in Stuttgart, Germany which is a forum to discuss the latest advancements in the parallel tools.

Cellular Computing

www.ebooks.com/cj.asp?IID=279831&cjsku=279831...
The completion of the first draft of the human genome has led to an explosion of interest in genetics and molecular biology. The view of the genome as a network of interacting computational components is well-established, but researchers are now trying to reverse the analogy, by using living organisms to construct logic circuits. The potential applications for such technologies is huge, ranging from bio-sensors, through industrial applications to drug delivery and diagnostics. This book would be the first to deal with the implementation of this technology, describing several working experimental demonstrations using cells as components of logic circuits, building toward computers incorporating biological components in their functioning.

Computing Action

www.ebooks.com/cj.asp?IID=325665&cjsku=325665...
Computing Action takes a new approach to the phenomenon of narrated action in literary texts. It begins with a survey of philosophical approaches to the concept of action, ranging from analytical to transcendental and finally constructivist definitions. This leads to the formulation of a new model of action, in which the core definitions developed in traditional structuralist narratology and Greimassian semiotics are reconceptualised in the light of constructivist theories. In the second part of the study, the combinatory model of action proposed is put into practice in the context of a computer-aided investigation of the action constructs logically implied by narrative texts. Two specialised literary computing tools were developed for the purposes of this investigation of textual data: EVENTPARSER, an interactive tool for parsing events in literary texts, and EPITEST, a tool for subjecting the mark-up files thus produced to a combinatory analysis of the episode and action constructs they contain. The third part of the book presents a case study of Goethe's Unterhaltungen deutscher Ausgewanderten. Here, the practical application of theory and methodology eventually leads to a new interpretation of Goethe's famous Novellenzyklus as a systematic experiment in the narrative construction of action - an experiment intended to demonstrate not only Goethe's aesthetic principles, but also, and more fundamentally, his epistemological convictions.
