Past Present Parallel

Past, Present, Parallel is a survey of the current state of the parallel processing industry. In the early 1980s, parallel computers were generally regarded as academic curiosities whose natural environment was the research laboratory. Today, parallelism is being used by every major computer manufacturer, although in very different ways, to produce increasingly powerful and cost-effec- tive machines. The first chapter introduces the basic concepts of parallel computing; the subsequent chapters cover different forms of parallelism, including descriptions of vector supercomputers, SIMD computers, shared memory multiprocessors, hypercubes, and transputer-based machines. Each section concentrates on a different manufacturer, detailing its history and company profile, the machines it currently produces, the software environments it supports, the market segment it is targetting, and its future plans. Supplementary chapters describe some of the companies which have been unsuccessful, and discuss a number of the common software systems which have been developed to make parallel computers more usable. The appendices describe the technologies which underpin parallelism. Past, Present, Parallel is an invaluable reference work, providing up-to-date material for commercial computer users and manufacturers, and for researchers and postgraduate students with an interest in parallel computing.

In the politico-religious history of the Deuteronomists, past, present and future mingle in an often inextricable way. Long obsolete traditions, which had been unacceptable to the Davidic dynasty, were rediscovered and adapted to the aims of the Deuteronomists. Personages of the past were condemned and blackened in the light of the new ideology, whereas others were glorified and embellished as heroes of faith because their ideas suited the historians. This inevitably raises the question whether the Bible can be trusted as a source book for writing a history of Israel. Apparently not, say scholars like T.L. Thompson, P.R. Davies and N.P. Lemche. In this volume a number of authors take up this challenge, stating that the radical rejection of the biblical testimony in favour of a history based mainly on archaeology is ill-advised. Several contributions to this volume draw instructive parallels between the process of re-writing the history of South Africa and the work of the Deuteronomists.

What if you woke up to a new life every day? A collision of universes leaves Abby living two lives at once - and sharing them with her own double. Two worlds. Two guys. Two selves. How will she stay in control?

What makes our brain a brain? This is the central question posited in Unlocking the Brain. By providing a fascinating venture into different territories of neuroscience, psychiatry, and philosophy, the author takes a novel exploration of the brain's resting state in the context of the neural code, and its ability to yield consciousness.
