摘要： A service module that provides for discovery of one or more network interfaces connecting a prospective remote procedure call (RPC) client, facilitates the provision of RPC programs in a network including multi-horned systems. When a request for a network address to an RPC application providing an RPC program is received from the RPC client, the RPC bind daemon discovers from the module, using the client response address, over which interface(s) the client is accessible. The daemon then selects an address of a network path to the RPC application that the prospective client can access and returns the corresponding network address. The service module monitors the network stack for RPC get address requests and builds tables of client address entries with corresponding network interface identifiers. The entries are retired according to an aging policy. When multiple network paths to the RPC application are available, the service can be selected using a heuristic such as preferred interface, non-firewalled interface, least number of return path links or other criteria.

摘要： Functionality can be implemented in a virtual memory manager (VMM) to allow small pages (e.g., 4 KB) to be coalesced into large pages (e.g., 64 KB), so that a single free list can be maintained for the large pages (“maintained pages”). When a process requests a small page, the VMM can associate a maintained page with a memory segment accessible by the process. Then, the maintained page can be divided to form a set of small pages (“fragments”). The fragments can become available pages in a broken page list. The VMM can satisfy the request by allocating one of the fragments in the broken page list. If the process requests additional small pages, the additional requests can be satisfied from the broken page list. When the process terminates, the fragments in the broken page list become a maintained page and can be returned to the free list.

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 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： A computer implemented method, apparatus, and computer usable code for managing cache data. A partition identifier is associated with a cache entry in a cache, wherein the partition identifier identifies a last partition accessing the cache entry. The partition identifier associated with the cache entry is compared with a previous partition identifier located in a processor register in response to the cache entry being moved into a lower level cache relative to the cache. The cache entry is marked if the partition identifier associated with the cache entry matches the previous partition identifier located in the processor register to form a marked cache entry, wherein the marked cache entry is aged at a slower rate relative to an unmarked cache entry.

摘要： A method, system, device, and article of manufacture for use in a computer memory system utilizing multiple page types, for handling a memory resource request. In a accordance with the method of the invention, a request is received for allocation of pages having a first page type. The first page type has a specified allocation limit. A determination is made in response to the page allocation request of whether the number of allocated pages of the first page type exceeds or is below the allocation limit. In response to determining that the number of allocated pages of said first page type is below the allocation limit, the virtual memory manager enables allocation of pages for the request to exceed the allocation limit.

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 method, computer program product, and a data processing system for processing transactions of a client-server application is provided. A first data set is transmitted from a client to a server. A second data set to be transmitted to the server is received by the client. An evaluation is made to determine whether transmission of the second data set is blocked until receipt of an acknowledgment of the first data set. A number of allowable outstanding acknowledgements is increased responsive to determining that the second data set is blocked from transmission.

摘要： A system and method for identifying compatible threads in a Simultaneous Multithreading (SMT) processor environment is provided by calculating a performance metric, such as 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.

摘要翻译： 通过计算在SMT处理器上运行两个线程时发生的性能度量（如CPI），可以提供用于识别同时多线程（SMT）处理器环境中的兼容线程的系统和方法。 确定在两个线程在SMT处理器上执行时实现的CPI。 如果实现的CPI优于兼容性阈值，则记录指示兼容性的信息。 当线程即将完成时，调度程序将查看完成线程所属的运行队列，以调度另一个线程。 调度程序标识（1）与SMT处理器上仍然运行的线程（即，即将完成的线程）兼容的线程，以及（2）准备执行。 持续更新CPI数据，以便不断地识别彼此兼容的线程。
