Алгоритмы для разреженных систем линейных уравнений в GF (2) >Algorithms for Large Sparse Linear Systems over the Field GF(2): Manual

‘Workhorses’ of all computational mathematics are systems of linear equations and programs that can provide a quick solution to systems of linear equations. The manual considers algorithms for solving large sparse systems of linear equations over the field GF (2) obtained by sieve methods when solving the problem of decomposing a large natural number into a product of two simple ones. The total number of operations for the systems and algorithms under consideration is so great that the only way to solve such problems is to use parallel technologies. The book analyzes parallel properties of the two most widely used algorithms: the Montgomery multiplication algorithm and the Wiedemann-Coppersmith method. Parallel implementations of algorithms are obtained by applying simple general principles for creating parallel programs.

The book gives examples of real calculations that confirm the correctness of analytical conclusions.

It also provides an overview of the methods used to assimilate meteorological data and justifies the choice of the algorithms that are most suitable for implementation on a massively parallel architecture.

Новые алгоритмы вычислительной гидродинамики для многопроцессорных вычислительных комплексов >New Algorithms of Computational Hydrodynamics for Multiprocessor Computing Systems

This monograph, which is intended for undergraduate and postgraduate students and researchers, has gathered and systematized the material of long-term work by a large group of specialists in the field of mathematical modeling and computational mathematics. Of many directions and approaches that compete with one another in the modern world, the authors have chosen a relatively new direction called the ‘CABARE’ method, which they have been involved in developing in this or other extent. This approach, which is being developed at Lomonosov Moscow State University, Nuclear Safety Institute, Russian Academy of Sciences (IBRAE), Central Institute of Aerohydrodynamics (TsAGI) and a number of other Russian and foreign institutions (Cambridge University, Queen Mary University of London), has good competitive positions and is actively developing. The present monograph describes in detail the key idea of the ‘CABARE’ method in its development from the simplest linear one-dimensional equations of the hyperbolic type to the methods for solving multidimensional problems of hydrodynamics and gas dynamics on unstructured grids in complex spatial domains characteristic of industrial mathematical applications.

The book can be considered as a study guide and serve as the basis for developing a computational workshop on methods for solving equations of mathematical physics with the dominant processes of grid transfer.
