摘要： Methods, systems, and computer program products are provided for scheduling threads in a multiprocessor computer. Embodiments include selecting a thread in a ready queue to be dispatched to a processor and determining 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, embodiments typically include selecting a processor, setting a current processor priority register of the selected processor to least favored, and dispatching the thread from the ready queue to the selected processor. In some embodiments, setting the current processor priority register of the selected processor to least favored is carried out by storing a value associated with the highest interrupt priority in the current processor priority register.

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.
摘要翻译：一种用于在多处理器计算机中调度线程的计算机程序产品包括计算机程序指令，其被配置为选择准备队列中的线程以分派到处理器，并且确定是否在与线程相关联的线程控制块中设置了中断屏蔽标志。如果在与线程相关联的线程控制块中设置了中断屏蔽标志，则将计算机程序指令配置为选择处理器，将所选处理器的当前处理器优先级寄存器设置为最不利，并将线程从就绪队列到所选择的处理器。
