Abstract

Data processing apparatus comprises one or more interconnected processing elements each configured to execute processing instructions of a program task; coherent memory circuitry storing one or more copies of data accessible by each of the processing elements, so that data written to a memory address in the coherent memory circuitry by one processing element is consistent with data read from that memory address in the coherent memory circuitry by another of the processing elements; the coherent memory circuitry comprising a memory region to store data, accessible by the processing elements, defining one or more attributes of a program task and context data associated with a most recent instance of execution of that program task; the apparatus comprising scheduling circuitry to schedule execution of a task by a processing element in response to the one or more attributes defined by data stored in the memory region corresponding to that task; and each processing element which executes a program task is configured to modify one or more of the attributes corresponding to that program task in response to execution of that program task.
