In some embodiments, an apparatus includes processor selection logic to receive logical destination identification numbers that are associated with interrupts each having a processor cluster identification number to identify a cluster of processors to which the interrupts are directed. The logical destination identification numbers are each to identify which processors within the identified cluster of processors are available to receive the corresponding one of interrupts. The processor selection logic is to select one of the available processors to receive the interrupt, and the selected oneof the available processors is identified through a relative position of a corresponding bit in the logical destination identification numbers. Other embodiments are described.
