Abstract

Many applied problems of high dimensionality require performing of high-precision numerical calculations in
the matrix algebra basis over a field of large numbers. Modern multiprocessor computer systems typically have 32 - or 64-bit architecture, which makes it difficult to perform operations on large numbers, and reduces the efficiency of these systems. A new method was proposed for performing calculations based on using the number system with parallel architecture as a basis for implementation of numerical calculations - a system of residual classes. Tool system is developed based on this method.


Keywords: software complex, scalable parallel calculations, system of residual classes, large numbers, MPI, OpenMP, technology of parallel programming, parallel programs
