Abstract: A computing system performs an environment-aware cache flushing method. When a processor in the system receives a signal to flush at least a portion of the caches to the system memory, the processor determines a flushing mechanism among multiple candidate flushing mechanisms. The processor also determines one or more of the active processors in the system for performing the flushing mechanism. The determinations are based on the extent of flushing indicated in the signal and a runtime environment that includes the number of active processors. The system then flushes the caches to the system memory according to the flushing mechanism.

Abstract: Systems, methods, and computer readable medium are provided that improve the management of interrupt requests in multiple processor computer systems. Interrupt requests can be classified into three categories and the structure of the categories provide for specifying a list that needs to be migrated. The list can contain only those interrupt requests that can be handled by some of the processors that will never unplug or based on affinity. When a processor is about to unplug, the computer system can migrate that list. The system can also manage the other interrupt requests.
