Abstract
A computer-processor-implemented data processing method comprises: a computer processor executing instances of one or more processing functions, each instance of a processing function having an associated function-call identifier; and in response to initiation of execution by the computer processor of a given processing function instance configured to modify one or more pointers of a partitioned acyclic data structure: the computer processor storing the function-call identifier for that processing function instance in a memory at a storage location associated with the partitioned acyclic data structure; for a memory location which stores data representing a given pointer of the partitioned acyclic data structure, the computer processor defining a period of exclusive access to at least that memory location by applying and subsequently releasing an exclusive tag for at least that memory location; and the computer processor selectively processing the given pointer during the period of exclusive access in dependence upon whether the function-call identifier of the prevailing processing function instance is identical to the function-call identifier stored in association with the partitioned acyclic data structure.
