    摘要： A system and associated method for mutually exclusively executing a critical section by a process in a computer system. The critical section accessing a shared resource is controlled by a lock. The method measures a detection time when a lock contention is detected, a wait time representing a duration of wait for the lock at each failed attempt to acquire the lock, and a delay representing a total lapse of time from the detection time till the lock is acquired. The delay is logged and used to calculate an average delay, which is compared with a suspension overhead time of the computer system to determine whether to spin or to suspend the process while waiting for the lock to be released. The number of processes waiting for the lock and the number of processes suspended are respectively counted to optimize the method.

    摘要： Memory management of processing systems running in a virtual computer environment and of processes running in an operating system environment includes identifying a usage pattern of a page in memory. The usage pattern is identified by tracking operations conducted with respect to the page. The memory management also includes designating the page as a candidate for sharing when the usage pattern reflects that a number of updates made to the page does not exceed a predefined threshold value. The candidate page is allocated to a first process or virtual machine. The memory management also includes sharing access to the candidate page with a second process or virtual machine when content in the candidate page matches content of page allocated for the second process or virtual machine to an address space of the candidate page.
