Abstract:

This article deals with the problem of computer simulation of large oil and gas deposits. The authors consider iterative conjugation of sector models by Schwartz’s method one of the existing methods of solution in domain decomposition. Previously implemented method, focused on multi-core workstation algorithm of conjugation, has been modifi ed because of the need to design and develop a new software system based on the distributed computing. The paradigm of object-oriented programming is taken as a basis for the new software package. Issues of system architecture defi ned structural components containing a basic functionality for the computations according to the algorithm. The authors consider tools for interaction between objects of the system required for distributed computing, the advantages and disadvantages of common approaches. Also, to increase the stability and improve the temporal characteristics of the work, the authors consider ways of solving the problem of fault tolerance in the distributed system and the approach to load balancing.
