Abstract
A method and apparatus for reserving and releasing routing paths in a parallel processing computer system. The present invention eliminates the need to restart the computer system to recover from a system seizure or an application stall. A plurality of signals are provided which convey various message transmission information to source, intermediate and destination nodes and routing elements. A first signal is used by a source node to reserve a route to a destination node. A second signal is used by the destination node to indicate that the message has reached the destination node and later that the entire message has been transmitted. A third signal is used by the destination node to signal that an error in transmission has been detected. Through various combinations of the signals transmission information is obtained and nodes in the route may be reserved and released.
