Abstract

A system for supervising operation of at least one machine of an industrial installation comprises a network having a server and a plurality of devices forming a computing cluster. The devices are connectable to a machine. Each device has a first processor configured to compute in real-time, with data acquirable from a machine to which the device is connected, a first processing task for solving a first query; and a second processor sharing its processing power with the network, and when assigned by the server, computing at least one thread of a second processing task for solving a second query. The server controls the computing cluster; partitions the second processing task into a plurality of threads, and assigns one or more threads of the plurality of threads to the second processor of the plurality of devices.
