The Parallel Substitution Algorithm (PSA) is a spatial dynamical system used to represent processes in cellular space. The PSA is applied to designing programs of self-replication in cellular space. The programs become more laconic (by the number of transition rules or substitutions) in comparison with the ones based on the...

Methods of Cellular Automata (CA) composition are systematically considered and analyzed. To formally define them some basic mathematical operations on cellular arrays are introduced. Trivial sequential and parallel composition types with no shared variables in cell transition functions are given in brief. The main concern is with two basic methods...

This paper describes the experience gained in the development of PABX monitoring system using the Internet-technologies. The basic attention is being given to the formal representation of data accounting, storage subsystems and access to data. Information about the system realization is given, and the user interface is described.

This paper presents the review of the network monitoring technologies that now are widely used. The main attention is given to MRTG, NETMON and NFC&NDA systems. The paper describes their advantages, configuring parameters and a necessary programming base. The experience of using these systems for monitoring the NSCnet network is...

With evolution of mathematical modeling, and with creation of high-performance computing systems, many scientific applications have appeared, demanding ever increasing computer costs, which are higher than any of available supercomputers can provide.

This paper is oriented to the cellular pipelined algorithm architecture for the 1D diffusion simulation. The finite difference representation of 1D diffusion is written in terms of the residue number system. The cellular pipelined algorithm architectures for the main operations with a minimum period are developed. The parallel Substitution Algorithm...

In this paper we describe in detail a new technique for updating tree paths on a model of associative parallel systems with vertical data processing (the STAR-machine). It includes a new associative parallel algorithm for finding an MST along with the matrix of tree paths and a new associative parallel...

This paper presents a Dynamically Configurable Modular System (DCMS), which is a library for the development of applications with an open architecture. The DCMS is oriented to a wide set of applications, such as mathematical simulation, Web technologies, and so on. By now, the library has been used in the...

An algorithm for the real-time image rotation on the array microprocessor NM6403 is proposed. For implementation of this image transformation on the microprocessor NM6403, decomposition of a rotation matrix is used. This decomposition reduces any pixel rotation to a sequence of unidimensional translations which can be effectively vectorized.
