PROCESSING SYSTEM AND METHOD OF DETECTING CONGESTION IN PROCESSING SYSTEM

A method of detecting congestion in a computer system. The computer system has a task source for generating a stream of computer-implemented tasks and a plurality of processing nodes arranged in a sequence and forming a processing pipeline for processing the stream of computer-implemented tasks, each one of the plurality of processing nodes having a respective system-unique identifier (SUID). The method is executable by the computer system. The method includes receiving a task packet by a given processing node, the task packet having a task body indicative of a respective computer-implemented task, and a writable congestion-indicating field; processing the task body of the task packet; determining a presence of an input queue of more than one task packet at the given processing node; and in response to the determining the presence of the input queue, updating the writable congestion-indicating field with the SUID of the given processing node.
