The invention relates to task management in a data processing system, having a plurality of processing elements (CPU, ProcA, ProcB, ProcC). Therefore a data processing system is provided, comprising at least a first processing element (CPU, ProcA, ProcB, ProcC) and a second processing element (CPU, ProcA, ProcB, ProcC) for processing a stream of data objects (DS_Q, DS R, DS S, DST), the first processing element being arranged to pass data objects from the stream of data objects to the second processing element The first and the second processing element are arranged for parallel execution of an application comprising a set of tasks (TP, TA, TB1, TB2, TC), and the first and the second processing element are arranged to be responsive to the receipt of a unique identifier. In order to ensure integrity of data during reconfiguration of the application, the unique identifier is inserted into data stream and passed from one processing element to the other. Application reconfiguration is performed when the corresponding processing element receives the unique identifier, and as a result global application control is allowed at a unique location in the data space.
