The articles explore a problem of the synthesis and analyze models of subsystem "processor-memory" multiprocessor systems. The prime object is to study the architecture of the subsystem "processor-memory" of modern high-performance computing systems, calculation and comparison of the performance, as well as a conclusion on the effect of conflict over access to shared resources on the overall performance of the whole system. The objects of study of this work are the subsystem "processor-memory" multiprocessor computer systems, existing varieties of architectural construction of this subsystem. During researches the comparative analysis of systems with architecture UMA, NUMA and SUMA was carried out. Their merits and demerits were revealed. In the inference the appropriate conclusions on operation are drawn. The considered models allow making an assessment of characteristics of the multiprocessor systems without creation of a real prototype. At the expense of it economic effect as the assessment of characteristics of the designed systems and a choice of the most optimal variants can be carried out without creation of real system is reached. © 2006-2016 Asian Research Publishing Network (ARPN).

Different methods for the numerical description of the behavior of a fluid–fluid interface in an electric field are proposed. A variation in the base system of equations for dielectrics and weakly conducting fluids is demonstrated. A deterministic approach to the description of two-phase flows traveling under the effect of an electric field is used. The system of equations proposed by G. A. Ostroumnov is adopted as a basis for a quantitative description of electrohydrodynamic phenomena. The proposed approach is used in numerical simulation of processes that occur in the intra-electrode space of electrodispersers and electrocoalescers in order to optimize their design and attain the maximal effect of separation with minimum energy costs. © 2017 Springer Science+Business Media New York

Systems analysis methods were used to find ways to improve chemical-technological processes for creation and destruction of water-oil emulsions in an electric field. The chemical-technological system of an electric desalting unit (HTS-CDU) was divided into seven detailed subsystems. It is shown that the proposed approach allows consideration of various parameters affecting the system and provides a basis for the engineering design of processing equipment for the creation and destruction of an emulsion in an electric field. © 2017 Springer Science+Business Media New York

The article deals with mathematical modeling for analyzing the capacity of a multiprocessor system with Tasks Managers with the strategy of separation in space. Research methods are based on concepts of the analytical modeling theory, systems theory and queuing networks, probability theory and stochastic processes. The article presents analytical equations for the research of tasks managers with the strategy of separation in space for multiprocessor systems based on open queuing networks. The analytical part has been checked by simulation modeling. The dependence under study has been illustrated by diagrams. Finally, conclusions have been made. © 2006-2016 Asian Research Publishing Network (ARPN).

A simple scheme of the noise voltage generator with a Gaussian instantaneous-value distribution and specified energy spectrum bounds is presented. The scheme is based on emitter-coupled logic (ECL) microcircuits. As reference noise, the “digital” noise of the pseudorandom number generator, which is expressed via the contents sum of the set of its adjacent bits, is used. The “digital” noise is converted into an analog voltage by adding current quanta produced by the ϰ500ЛП115 differential receivers. The main characteristics of the device are as follows: the peak-to-peak amplitude of the differential noise voltage is 600 mV and the distribution law is normal. The noise energy spectrum is bounded from above by the clock rate and from below by the number of bits of the pseudorandom number generator. In the tested prototype with a clock rate of 10 MHz, it varies from 78 kHz to 6 MHz. © 2015, Pleiades Publishing, Inc.
