DYNAMIC ROUTING BASED ON INFORMATION OF NOT RESPONDED ACTIVE SOURCE REQUESTS QUANTITY RECEIVED IN BROADCAST HEARTBEAT SIGNAL AND STORED IN LOCAL DATA STRUCTURE FOR OTHER PROCESSOR CHIPS

A mechanism for performing dynamic request routing based on broadcast source request information is provided. Each processor chip in the system may use a synchronized heartbeat signal it generates to provide source request information to each of the other processor chips in the system. The source request information identifies the number of active source requests sent by the processor chip that originated the heartbeat signal. The source request 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.
