摘要： A mechanism is provided to determine an average rate of duplicate packets per connection for packets received by a node over an interface. The mechanism selects a connection from the connections established over the interface, determines that a rate of duplicate packets for the selected connection exceeds the average rate of duplicate packets by a threshold percentage, and sends a message to a transmitter of the duplicate packets over the connection to increase a timeout interval to retransmit packets.

摘要： Methods and arrangements of network communications are discussed. Embodiments include transformations, code, state machines or other logic to determine an average rate of duplicate packets per connection for packets received by a node over an interface. The embodiment may involve selecting a connection from the connections established over the interface, determining that a rate of duplicate packets for the selected connection exceeds the average rate of duplicate packets by a threshold percentage, and sending a message to a transmitter of the duplicate packets over the connection to increase a timeout interval to retransmit packets. Another embodiment may provide an apparatus for increasing a timeout interval to retransmit packets. Still another embodiment may provide a computer program produce for increasing a timeout interval to retransmit packets.

摘要： Input/output (I/O) requests generated by processes are typically stored in I/O queues. Because the queued I/O requests may not be associated with the processes that generated them, changing a process' priority may not affect the priority of the I/O requests generated by the process. Therefore, after the process' priority has been increased, it may be forced to wait for an I/O handler to service its I/O request, which may be stuck behind an I/O request generated by a lower priority process. Functionality can be implemented to associate the processes' priorities with the I/O requests generated by the processes. Also, reordering the queued I/O requests to reflect changes in the processes' priorities can ensure that the I/O requests from high priority processes are serviced before the I/O requests from low priority processes. This can ensure efficient processing and lower wait times for high priority processes.
摘要翻译：由进程生成的输入/输出（I / O）请求通常存储在I / O队列中。因为排队的I / O请求可能不与生成它们的进程相关联，所以更改进程的优先级可能不会影响进程生成的I / O请求的优先级。因此，在进程优先级增加之后，可能迫使其等待I / O处理程序来服务其I / O请求，这可能会被较低优先级进程生成的I / O请求所困扰。可以实现功能，将进程的优先级与进程生成的I / O请求相关联。此外，重新排序排队的I / O请求以反映进程优先级的更改可以确保在优先级较低的进程的I / O请求之前对来自高优先级进程的I / O请求进行服务。这可以确保高优先级进程的有效处理和较短的等待时间。

摘要： A computer-implemented system, method, and program product is disclosed for managing memory pages in a memory that includes a page replacement function. The method includes detecting that a sequence of pages is read by an application into the memory. The method continues by initiating a read-ahead to access a plurality of pages including the sequence of pages and a next page that has not yet been read, and storing the plurality in a page frame table of the memory. During the read-ahead, the method sets a soft-pin bit in the page frame table corresponding to each of the pages of the plurality of pages in the read-ahead. Each the soft-pin bit temporarily reserves its respective page from replacement by the page replacement function.

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.

摘要： A system and method for implementing a fast file synchronization in a data processing system. A memory management unit divides a file stored in system memory into a collection of data block groups. In response to a master (e.g., processing unit, peripheral, etc.) modifying a first data block group among the collection of data block groups, the memory management unit writes a first block group number associated with the first data block group to system memory. In response to a master modifying a second data block group, the memory management unit writes the first data block group to a hard disk drive and writes a second data block group number associated with the second data block group to system memory. In response to a request to update modified data block groups of the file stored in the system memory to the hard disk drive, the memory management unit writes the second data block to the hard disk drive.

摘要： A method, system, and program for facilitating presentation and monitoring of electronic mail messages with reply by constraints are provided. Within a network environment, a server receives electronic mail messages with separate selected reply by dates, wherein each electronic mail message is addressed for delivery by the server to at least one particular recipient. The server enables, for display within a user interface accessible to the particular recipient, a separate record for each electronic mail message within an inbox. The inbox include at least one selectable sublevel, wherein upon selection of the particular selectable sublevel of the inbox, only a selection of records for electronic mail messages with a same reply by date as the selectable sublevel are displayed within the user interface.
