The computational complexity for parallel implementation of multidomain spectral methods is studied to derive the optimal number of subdomains, q, and spectral order, n, for numerical solution of hyperbolic problems. The complexity analysis is based upon theoretical results which predict error as a function of (q, n) for problems having wave-like solutions. These are combined with a linear communication cost model to study the impact of communication over-head and imposed granularity on the optimal choice of (q, n) as a function of the number of processors. It is shown that, for present day multicomputers, the impact of communication overhead does not significantly shift (q, n) from the optimal uni-processor values, and that the effects of granularity are more important.

Caroline Auguste Fischer geb. Venturini war eine deutsche Schriftstellerin und Frauenrechtlerin. Sie schreibt mit viel Witz und Ironie. In ihren Märchen karikiert sie die Marotten ihren Mitmenschen und nimmt die Affektiertheit des Hoflebens aufs Korn. (Summary by Wikipedia und Hokuspokus)

2Beethoven, A Character Study

A book of the life of the German Composer, Beethoven. - Summary by Jessie Yun

3Piano Tuning: A Simple and Accurate Method for Amateurs

By Jerry Cree Fischer

This is a primer for anyone wishing to learn how to tune and maintain their own piano or to become a piano tuner. Written in 1907, it was targeted at a definite need for additional piano maintenance professionals in those days when pianos were almost ubiquitous. In addition, there are several chapters dealing with the theory and application of temperaments which will be of interest to any serious student of music. Please note that Concert Pitch as used in the book equates to A-454, considerably higher than today's standard of A-440.- Summary by JHedrick

This work brings new understanding of the life and work of Samuel Clemens (Mark Twain) while living and traveling abroad. Twain and fellow humorist Eugene Field experienced a wide variety of people, places and things together and author Henry Fischer brings them together here, for the first time. - Summary by John Greenman
