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 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： A computer program product for scheduling threads in a multiprocessor computer comprises computer program instructions configured to select a thread in a ready queue to be dispatched to a processor and determine 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, the computer program instructions are configured to select a processor, set a current processor priority register of the selected processor to least favored, and dispatch the thread from the ready queue to the selected processor.

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： 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.
