Resolution of dynamic priority conflict in a multi-processor computer system having shared resources

摘要

In a multi-processor computer system having shared resources and to provide a system and method for fair dynamic priority conflict resolution in the case of the multi-processor requiring access to the supply resource has a priority level of the share. If the priority of the isotopes, or, in the case where only a single port is active, dynamic conflict resolution general scheme to ensure a fair resolution of the isotopic state or conflict it has been changed. If it is determined that the pair state of the priority conflict, one of the plurality of processor elements are selected based on the priority level given. Identification information of the processor element is selected, the configuration of the pair state of the priority conflict is stored. If the pair state of priority conflict has the same configuration as the pair state of priority to conflict before occurs next, the processor element that is selected in Thailand state of before, in the configuration of the pair state of the priority of specific are not selected in the pair state at the time of priority conflicts that processor elements until all selected, the next occurrence. In a situation with only one active port, modify the dynamic conflict resolution scheme is traditional, will also give a fair access, to reduce the conflicts in pair state priority.
