Computer program product for scheduling ready threads in a multiprocessor computer based on an interrupt mask flag value associated with a thread and a current processor priority register value

摘要

A computer program product for scheduling threads in a multiprocessor computer comprises computer program instructions configured to select a thread in a ready queue to be dispatched to a processor and determine whether an interrupt mask flag is set in a thread control block associated with the thread. If the interrupt mask flag is set in the thread control block associated with the thread, the computer program instructions are configured to select a processor, set a current processor priority register of the selected processor to least favored, and dispatch the thread from the ready queue to the selected processor.
