A number of counters are assigned for the event to each of a plurality of threads running for a plurality of applications on a plurality of processor cores, wherein each of the counters includes a thread identifier in the interrupt thread identification field and a processor identifier in the processor identification field. The number of counters is configured to have a number of interrupt thread identification fields and a number of processor identification fields to identify a thread that will receive a number of interrupts.
