A multiprocessor computer system includes an exception domain having multiple thread contexts (TCs) each having a restart address register, and a timer that generates a periodic interrupt request to the exception domain. The exception domain selects an eligible TC to service the interrupt request, which is non-specific regarding which TC to select. A first interrupt handler executes on the selected TC to service the interrupt request to schedule a set of processes assigned by the SMP OS for execution on the selected TC, and write an address of a second interrupt handler to the restart address register of each TC other than the selected TC. The second interrupt handler schedules a plurality of sets of processes assigned by the SMP OS for execution on respective ones of the TCs other than the selected TC. |
