    摘要： A system, apparatus and method of reducing cache thrashing in a multi-processor with a shared cache executing a disruptive process (i.e., a thread that has a poor cache affinity or a large cache footprint) are provided. When a thread is dispatched for execution, a table is consulted to determine whether the dispatched thread is a disruptive thread. If so, a system idle process is dispatched to the processor sharing a cache with the processor executing the disruptive thread. Since the system idle process may not use data intensively, cache thrashing may be avoided.

    摘要翻译： 提供了一种使用执行破坏性过程的共享高速缓存（即，具有差的缓存关联性或大的缓存占用空间的线程）的多处理器中的缓存颠簸的系统，装置和方法。 当一个线程被调度执行时，查询一个表以确定被调度的线程是否是一个中断线程。 如果是这样，系统空闲进程将被分配到与执行中断线程的处理器共享高速缓存的处理器。 由于系统空闲进程可能不会集中使用数据，因此可以避免缓存抖动。

    摘要： Methods, systems, and products are disclosed for user defined preferred DNS routing that include mapping for a user in a data communications application a domain name of a network host to a network address for a preferred DNS server, wherein the preferred DNS server has a network address for the domain name; receiving from the user a request for access to a resource accessible through the network host; and routing to the preferred DNS server a DNS request for the network address of the network host, the DNS request including the domain name of the network host. In typical embodiments, mapping a domain name to a network address for a preferred DNS server is carried out by storing, through the data communication application, the domain name in association with the network address for a preferred DNS server in a data structure in computer memory.

    摘要： A method, apparatus, processor, system, and signal-bearing medium that in an embodiment determine which page to replace in memory when the memory is full based on reference and re-reference indicators in page table entries. In an embodiment, a reference indicator in an entry is set when its associated page is accessed in memory and the reference indicator was previously clear. The re-reference indicator in an entry is set when its associated page is accessed and the reference indicator was previously set. Both the reference and re-reference indicators are cleared if their associated page is accessed and both were previously set. When a new page is accessed and the memory is full, a page in the memory is not available for replacement if both its reference and its re-reference indicators are set. Otherwise, the page is available for replacement.

    摘要： Management of a UNIX-style storage pools is enhanced by specially managing one or more memory management inodes associated with pinned and allocated pages of data storage by providing indirect access to the pinned and allocated pages by one or more user processes via a handle, while preventing direct access of the pinned and allocated pages by the user processes without use of the handles; scanning periodically hardware status bits in the inodes to determine which of the pinned and allocated pages have been recently accessed within a pre-determined period of time; requesting via a callback communication to each user process to determine which of the least-recently accessed pinned and allocated pages can be either deallocated or defragmented and compacted; and responsive to receiving one or more page indicators of pages unpinned by the user processes, compacting or deallocating one or more pages corresponding to the page indicators.

    摘要： Systems, methods and computer program products may provide managing utilization of one or more physical processors in a shared processor pool. A method of managing utilization of one or more physical processors in a shared processor pool may include determining a current amount of utilization of the one or more physical processors and generating an instruction message. The instruction message may be at least partially determined by the current amount of utilization. The method may further include sending the instruction message to a guest operating system, the guest operating system having a number of enabled virtual processors.

    摘要： An approach is provided that reserves a software lock for a waiting thread is presented. When a software lock is released by a first thread, a second thread that is waiting for the same resource controlled by the software lock is woken up. In addition, a reservation to the software lock is established for the second thread. After the reservation is established, if the lock is available and requested by a thread other than the second thread, the requesting thread is denied, added to the wait queue, and put to sleep. In addition, the reservation is cleared. After the reservation has been cleared, the lock will be granted to the next thread to request the lock.

    摘要： The present invention provides a computer implemented method and apparatus to assign software threads to a common virtual processor of a data processing system having multiple virtual processors. A data processing system detects cooperation between a first thread and a second thread with respect to a lock associated with a resource of the data processing system. Responsive to detecting cooperation, the data processing system assigns the first thread to the common virtual processor. The data processing system moves the second thread to the common virtual processor, whereby a sleep time associated with the lock experienced by the first thread and the second thread is reduced below a sleep time experienced prior to the detecting cooperation step.
