Abstract
To reach the effective organization of distributed computational processes it is important to provide the functionality at the level appropriate for guaranteed and successful execution of computational processes of the task being solved. Solving the problem of distributed computer systems (DCS) functionality provision has become particularly acute in connection with following factors. DCS has become a popular instrument; distributed computation nowadays is becoming a widely used instrument to solve different classes of practical tasks. Multiplicity and variety designation of the tasks being solved have brought to the fact that both DCS functionality and information-computation processes fulfilled by DCS turned out to be diversiform, complex with multiple properties and characteristics.
