Abstract: A system is presented for a plurality of computer nodes in mutual data communication to execute logic in a coordinated manner. The approach features aligning the definition of the time in the nodes so that each node has essentially the same definition of time; defining a schedule of communications for each computer node, with the schedule having future moments defined for initiating each communication; communicating each schedule to its respective node; and initiating each communication at the time defined in the schedule. The computer network has a message carrier supporting multiple communication paths; a plurality of computers coupled to the message carrier, a clock system for maintaining time synchronism among the computers; and a scheduler coupled to the message carrier for determining the sequence of communication between the computers. The message carrier establishes communication between selected computers based on the time-deterministic tasks being performed by the computers.
