摘要:
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 requesters that share the resource. Each of the requesters is associated with a priority weight that indicates a probability that the associated requester 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 requesters. In response to the current priorities of the requesters, a request for access to the resource is granted. In one embodiment, a requester corresponding to a granted request is signaled that its request has been granted, and a requester corresponding to a rejected request is signaled that its request was not granted.
