ABSTRACT OF THE DISCLOSURE An operations controller (12) for a multiple node fault tolerant processing system having a transmitter (30) for transmitting inter-node messages, a plurality of receivers (32a...32n), each receiving inter-node messages from only one of the nodes and a message checker (34) for checking each received message for physical and logical errors. A fault tolerator (36) assembles all of the errors detected and decides which nodes are faulty based on the number and severity of the detected errors. A voter (38) generates a voted value for each value which is received from the other nodes which is stored in a data memory (42) by a task communicator (44). A scheduler (40) selects the tasks to be executed by an applications processor (14) which is passed to the task communicator (44). The task communicator (44) passes the selected task and the data required for the execution of that task to the applications procesor (14) and transmits the data resulting from that task to all of the nodes in the system. A synchronizer (46) synchronizes the operation of its own node with all of the other nodes in the system.
