    摘要： Embodiments of the present invention relate to a system and method for providing processing capacity on demand. According to the embodiments, a processor package has a plurality of processing elements. One or more of the processing elements may be made active in response to increased demand for processing capacity based on modifiable authorization information.

    摘要： In one aspect of the invention is a method to synchronize accesses by multiple threads to shared resources. The method entails a first thread entering a processing queue to contend for a lock on a shared resource. If a second thread exists, where the second thread is currently executing code, then the first thread may execute the critical section of code if the second thread is not currently executing the critical section; or if the second thread is currently executing the critical section of code, then the first thread may continue to contend for ownership of the shared resource until the second thread relinquishes ownership of the shared resource, or until a yield count expires.

    摘要： A method and apparatus for power management is disclosed. The invention reduces power consumption in multiprocessing systems by dynamically adjusting processor power based on system workload. Particularly, the method and apparatus determines the number of required processors based on the number or active threads and sets a processor affinity to run the active threads on the determined number of required processors, thereby allowing the free processors to enter a low-power state.

    摘要： Mechanisms for handling multiple data errors that occur simultaneously are provided. A processing device may determine whether multiple data errors occur in memory locations that are within a range of memory locations. If the multiple memory locations are within the range of memory locations, the processing device may continue with a recovery process. If one of the multiple memory locations is outside of the range of memory locations, the processing device may halt the recovery process.

    摘要翻译： 本发明的一个方面是将多个线程的访问同步到共享资源的方法。 该方法需要第一个线程进入处理队列以争取共享资源上的锁定。 如果第二个线程存在第二个线程正在执行代码的第二个线程，那么如果第二个线程当前没有执行临界部分，则第一个线程可以执行代码的关键部分; 或者如果第二个线程当前正在执行代码的关键部分，那么第一个线程可能会继续争夺共享资源的所有权，直到第二个线程放弃共享资源的所有权，或直到产生计数到期。
