Abstract
Mechanisms for performing dynamic request routing based on broadcast depth queue information are provided. Each processor chip in the system may use a synchronized heartbeat signal it generates to provide queue depth information to each of the other processor chips in the system. The queue depth information identifies a number of requests or amount of data in each of the queues of a processor chip that originated the heartbeat signal. The queue depth information from each of the processor chips in the system may be used by the processor chips in determining optimal routing paths for data from a source processor chip to a destination processor chip. As a result, the congestion of data for processing at each of the processor chips along each possible routing path may be taken into account when selecting to which processor chip to forward data.
