S.S. Tolstyh, V.E. Podolsky.


In article questions of an evaluation of complexity of large-block cloud computing with enhanced accuracy are considered. This development is directed on the decision in a cloud of tasks of mathematical simulation with special requirements of accuracy. In particular it is about obtaining the precision and confidential solution of tasks with complex couplings between subtasks in the form of large blocks and the score time considerably exceeding transmission time of information in between. The methodology of an evaluation of complexity of tasks of this sort used for creation of the computing systems, optimum on productivity functioning in the cloudy environment is offered.
