Computer system for calculating and computing method implemented by means of such a system

This computer calculation system comprises a plurality of computers (12, ..., 22) mounted in each network which is stored at least one calculation application, and a machine (10) data storage computing connected to the network and in communication with the computers, at least one (12) of computers operating in master computer and at least one of the other computers (14, ..., 22) operating in slave computer. At least one of the computers comprises, stored in memory, a configuration algorithm of the other computers of the slave computer in the network and a master executable application for managing tasks of each slave computer (14, ..., 22) based their availability for assignment to each of these computational tasks and corresponding calculation data stored in the machine (10) storage.
