ABSTRACT:
A method and system for controlling access to a shared resource in a data processing system are described. According to the method, a number of requests for access to the resource are generated by a number of requestors that share the resource. Each of the requestors is dynamically associated with a priority weight in response to events in the data processing system. The priority weight indicates a probability that the associated requestor will be assigned a highest current priority. Each requester is then assigned a current priority that is determined substantially randomly with respect to previous priorities of the requestors. In response to the current priorities of the requestors, a request for access to the resource is granted.
