摘要： Management of a UNIX-style storage pools is enhanced by specially managing one or more memory management inodes associated with pinned and allocated pages of data storage by providing indirect access to the pinned and allocated pages by one or more user processes via a handle. Direct access of the pinned and allocated pages by the user processes without use of the handles is prevented. Hardware status bits in the inodes are scanned to determine which pinned and allocated pages have been recently accessed and callback communication to each user process is used to determine which of the least-recently accessed pages can be deallocated, defragmented and compacted.

摘要： Systems, methods and computer program products may provide managing utilization of one or more physical processors in a shared processor pool. A method of managing utilization of one or more physical processors in a shared processor pool may include determining a current amount of utilization of the one or more physical processors and generating an instruction message. The instruction message may be at least partially determined by the current amount of utilization. The method may further include sending the instruction message to a guest operating system, the guest operating system having a number of enabled virtual processors.

摘要： A method manages memory paging operations. Responsive to a request to page out a memory page from a shared memory pool, the method identifies whether a physical space within one of a number of paging space devices has been allocated for the memory page. If physical space within the paging space device has not been allocated for the memory page, a page priority indicator for the memory page is identified. The memory page is then allocated to one of a number of memory pools within one of the number of paging space devices. The memory page is allocated one of the memory pools according to the page priority indicator of the memory page. The memory page is then written to the allocated memory pools.

摘要： A method, system, and computer usable program product for selective memory compression for multi-threaded applications are provided in the illustrative embodiments. An identification of a memory region that is shared by a plurality of threads in an application is received at a first entity in a data processing system. A request for a second entity in the data processing system to keep the memory region uncompressed when compressing at least one of a plurality of memory regions that comprise the memory region is provided from the first entity to the second entity.

摘要： An information handling system (IHS) loads an application that may include startup code and steady state operation code. The IHS allocates one region of system memory to the startup code and another region of system memory to the steady state operation code. A programmer inserts a memory release call command at a location that marks the end of execution of the startup code. After executing the startup code, the operation system receives the memory release call command. In response to the memory release call command, the operating system releases or de-allocates the region of memory to which the IHS previously assigned to the startup code. This enables the released memory for use by code other than the startup code, such as other code pages, library pages and other code.

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.
