Abstract
In a virtual time system employing parallel processing nodes, processor nodes communicate with each other by sending messages. Each message between any pair of processing nodes is labeled with a sequence number, which allows the system to determine which messages are 'in-transit' at any point in time. In the invention, sequence numbers are drawn in a sending processing node from a finite range according to a method that permits them to be reused through time while providing unique sequence numbers with respect to other messages sent since a last received sequence number provided by a receiving processing node. The last received sequence number is the message sequence number in a last message sent by the sending processing node to the receiving processing node.
