Abstract: 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.

Abstract translation: 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。

Abstract: Disclosed is a computer implemented method and apparatus to secure a routing path. A local node receives a request for secure route identification from an upstream node. Responsive to receiving a request for secure route identification, the local node transmits a local node security level and an authentication key to the upstream node. The local node determines whether at least one downstream node is authentic and has sufficient security level from a second-level downstream node. The local node may then establish a socket to the upstream node.

Abstract: 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.

Abstract: 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.

Abstract: A mechanism is provided for automatically closing a file or a device. A service routine monitor monitors a request received from either an application that opened the file or a device driver that readied the device. The service routine monitor determines whether the file or the device has been accessed within a predetermined time interval. Responsive to the file or the device failing to be accessed within the predetermined time interval, the service routine monitor sends a call to the application that opened the file or the application or a higher level device driver that requested that the device driver ready the device. Responsive to a response from the application or the higher level device driver indicating that the use of the file or the device is no longer needed, the service routine monitor closes the file or quiesces the device.

Abstract: 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.
