摘要： A method is provided for a data processing system configured to include multiple logical partitions, wherein resources of the system are selectively allocated among respective partitions. In the method, an entity such as a Partition Load Manager or a separate background process is used to manage resources based on locality levels. The method includes the step of evaluating the allocation of resources to each of the partitions at a particular time, in order to select a partition having at least one resource considered to be of low desirability due to its level of locality with respect to the selected partition. The method further comprises identifying each of the other partitions that has a resource matching the resource of low desirability, and determining the overall benefit to the system that would result from trading the resource of low desirability for the matching resource of each of the identified partitions. Resources are reallocated to trade the resource of low desirability for the matching resource of the identified partition that is determined to provide the greatest overall benefit for the system, provided that at least some overall system benefit will result from the reallocation.

摘要： A method, system, and program for managing memory page requests in a multi-processor data processing system determines a threshold value of available memory, and dynamically adjusts an allocation time to fulfill a page request if the available memory is below a threshold value. The allocation time to fulfill the page request is based upon a percentage of available memory pages once a page stealer commences a scan for pages. An allocation wait time is inversely proportionally adjusted depending upon the percentage of available memory. The allocation wait time has a duration that increases in time as the percentage of available memory decreases and decreases in time as the percentage of available memory increases. More specifically, an average time per page to allocate a page including a scan time for the scan in computing the average time is determined. Then a tunable value is applied to the average time to determine a wait time. In a preferred embodiment, user defined values are received that would control the allocation wait time before fulfilling a page request.

摘要： A computer implemented method, apparatus, and computer usable program product for utilizing instruction trace registers. In one embodiment, a value in a target processor register in a plurality of processor registers is updated in response to executing an instruction associated with program code. In response to updating the value in the target processor register, an address for the instruction is copied from an instruction address register into an instruction trace register associated with the target processor register. The instruction trace register holds the address of the instruction that updated the value stored in the target processor register.

摘要： Identifying compatible threads in a Simultaneous Multithreading (SMT) processor environment is provided by calculating a performance metric, such as cycles per instruction (CPI), that occurs when two threads are running on the SMT processor. The CPI that is achieved when both threads were executing on the SMT processor is determined. If the CPI that was achieved is better than the compatibility threshold, then information indicating the compatibility is recorded. When a thread is about to complete, the scheduler looks at the run queue from which the completing thread belongs to dispatch another thread. The scheduler identifies a thread that is (1) compatible with the thread that is still running on the SMT processor (i.e., the thread that is not about to complete), and (2) ready to execute. The CPI data is continually updated so that threads that are compatible with one another are continually identified.

摘要： A system and method is altering the priority of a process, or thread of execution, when the process acquires a software lock. The priority is altered when the lock is acquired and restored when the process releases the lock. Thread priorities can be altered for every lock being managed by the operating system or can selectively be altered. In addition, the amount of alteration can be individually adjusted so that a process that acquires one lock receive a different priority boost than a process that acquires a different lock. Furthermore, a method of tuning a computer system by adjusting lock priority values is provided.

摘要： A computer implemented methods data processing system, and computer program product for configuring a partition with needed system resources to enable an application to run and process in a secure environment. Upon receiving a command to create a short lived secure partition for a secure application, a short lived secure partition is created in the data processing system. This short lived secure partition is inaccessible by superusers or other applications. System resources comprising physical resources and virtual allocations of the physical resources are allocated to the short lived secure partition. Hardware and software components needed to run the secure application are loaded into the short lived secure partition.

摘要： A method facilitates instant message (IM) session transfer of messages intended for an IM user to a new IM session being established by the user. Existing IM sessions may be queried for active IM sessions when the user is connecting to an instant message service. If there is an active session for the user, the IM server will request the content and sender of active messages waiting for the user, and transfer this information to the new IM session being established for the user. In this way, the user does not “miss” IM message(s) intended for him or her while going between existing, active IM sessions and new IM sessions. As used herein, session or sessions refer to IM session or IM sessions.

摘要翻译： 一种方法有助于即将消息（IM）会话传送IM用户的消息到由用户建立的新IM会话。 当用户正在连接到即时消息服务时，可以查询现有IM会话用于活动IM会话。 如果用户有活动会话，则IM服务器将请求等待用户的活动消息的内容和发送方，并将该信息传送到为用户建立的新IM会话。 以这种方式，当在现有的，活动的IM会话和新的IM会话之间进行时，用户不会“错过”针对他或她的IM消息。 如本文所使用的，会话或会话是指IM会话或IM会话。

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.
