“…With regard to parallel CS, this problem is called the prediction of the execution time of complex software systems; the latter are usually defined by graph models and are considered as complexes of interrelated jobs (CIJ)tasks and / or their parallel-sequential fragments (subtasks, processes, program modules) [4][5][6][7][8].…”

To study the effective functioning and behavior of parallel computing systems (which may be an integral part of the Cyber-Physical System), a high-performance software package based on mathematical models, methods and algorithms for stochastic modeling has been developed at the design stage. This software package completely solves the design problem -the parameters of a computing system have been calculated: its computational power, the average value of task execution time or various tasks on homogeneous resources of a parallel computing system, the distribution function of the task execution time. Based on the analysis of the parameters obtained, as well as indicators of the reliability of the system, the configuration of a parallel computing system has been selected or the possibility of using a previously selected computing system to perform the task has been considered.

“…In [9,10] matrix expressions for evaluation of time intervals were obtained, but they are cumbersome enough for practice use. So, the known approach needs high computational resources, commensurable with compilation of program and experimental evaluation of time intervals under consideration [11,12].…”

Abstract. An ergodic semi-Markov process with the structure represented by the full graph with loops, which simulates a digital control algorithm that generated transactions onto an object, is investigated. Elementary simplifications for reduction of semi-Markov processes are defined. Recursive procedure for reduction of initial semi-Markov process structure till the model, which includes selected states with its links only, is proposed. Formulae for recalculation of probabilities, weighted densities and expectations of time of switching to linked states are obtained. It is shown that recursive procedure may be used also for calculation of time expectation of return the process to one of selected states that simplified the task of evaluation of time intervals between transactions in polling procedure.

“…As a result, it is possible to state that, to a certain degree, the result is an intellectual optimized system of choice-making [13,16,17]. The paper describes multi-criterion fuzzy management of computing resources with the help of linguistic variables, based on cluster analysis proposed by the authors [11][12][13]. The authors suggest using the settheoretic approach [8,9] that allows partitioning the input processing program into non-overlapping sets of equivalence classes, meeting such requirements as reflexivity, symmetry and transitivity, and further to implement cluster management of computing resources.…”

Abstract. The study suggests management of computing resources through set-theoretic clustering. The research proposes production modelling of knowledge -rules of managing explicit and fuzzy structures, according to their technical specifications: system productivity, number of computing modules, capacity of microprocessor memory, etc. The paper describes an algorithm of "evaluation of management criterion value", according to the additive utility function.
