 Inparcom_pg is a product of researches in Institute of Cybernetics with the ResearchandProduction Enterprises “Electronmash”
 Provides highperformance computing (3 intelligent computers produce knowledge of properties of a task computer model and generate algorithm and a parallel program on the base of the knowledge
What are the advances of Inparcom over other parallel computers?
 it guarantees the computer solution reliability for the tasks of engineering and science with uncertainty input data
 it includes a programmable computation scheme for the efficient solution of a concrete problem
 it frees user from the mathematical properties investigation, algorithm and parallel program development for the problems of engineering and science
 it saves user’s work approach habitual from personal computer.
You can work on Inparcom: locally using one of the hostcomputers, remotely via the Internet.
II. Personal intelligent supercomputer hybrid architecture

Hardware and software complex Inparcom_pg based on intelligent hybrid architecture personal supercomputer Manufactured jointly with SSPE «Electronmash» for mathematical modeling in defense industry, machinebuilding and civil building etc. Ensures highperformance computations (up to 3 ТFlops) in the format of personal computer at the expense of compression of computations within one node. Implements innovative function of automatic adaptive adjustment both of algorithm, program and computer’s architecture according to characteristics of the problem. In so doing an approximate nature of input data is taken into account and reliability of the obtained computer results is guaranteed. 
Intelligent numerical software has been created based on the processing of sparse structures by means of structural regularization, on the intellectualization of process of investigation and solving of problems of the computational mathematics as well as on the visualization of the applications software.
Components of program complexes LIRA, Nadra and WeldPredictions have been created on the basis of hybrid computations for the mathematical modeling of processes in the field of building, mass transfer and electric welding.
