摘要： A method includes atomically reading a next field of a current element of the linked list to determine a first value that encodes a first pointer to the first element and a first indication of an owner of the first element. The first indication of the owner is stored in a first of a plurality of multi-field reservation data structures. The operation includes determining whether the next field of the current element still indicates the first value. The operation includes reading the first element of the linked list via the first pointer if the next field of the current element still indicates the first value. If the next field of the current element indicates a current value different than the first value, the first indication of the owner is removed from the first multi-field reservation data structure, and storing and determining with the second value is repeated.

摘要： Disclosed is a computer implemented method and apparatus for marking as critical a virtual memory page in a data processing system. An operating system indicates to a virtual memory manager a virtual memory page selected for paging-out to disk. The operating system determines that the data processing system is using a cooperative memory over-commitment. The operating system, responsive to a determination that the data processing system is using cooperative memory over-commitment, marks the virtual memory page as critical, such that the virtual memory page remains in physical memory. The operating system, responsive to marking the virtual memory page as critical, sets the virtual memory page to a page-out state.

摘要： Disclosed is a computer implemented method, apparatus and computer program product for communicating virtual memory page status to a virtual memory manager. An operating system may receive a request to free a virtual memory page from a first application. The operating system determines whether the virtual memory page is free due to an operating system page replacement. Responsive to a determination that the virtual memory page is free due to the operating system page replacement, the operating system inhibits marking the virtual memory page as unused. Finally, the operating system may insert the virtual memory page on an operating system free list.

摘要： In one embodiment a method for migrating a workload from one processing resource to a second processing resource of a computing platform is disclosed. The method can include a command to migrate a workload that is processing and the process can be interrupted and some memory processes can be frozen in response to the migration command. An index table can be created that identifies memory locations that determined where the process was when it is interrupted. Table data, pinned page data, and non-private process data can be sent to the second processing resource. Contained in this data can be restart type data. The second resource or target resource can utilize this data to restart the process without the requirement of bulk data transfers providing an efficient migration process. Other embodiments are also disclosed.

摘要： Controlled partition shut-down is provided within a shared memory partition data processing system including a shared memory partition, a paging service partition, a hypervisor and a shared memory pool within physical memory. The hypervisor manages access to logical pages within the pool and page-out of pages from the pool to external paging storage via the paging service partition. A respective paging service stream exists between the paging service partition and hypervisor for each shared memory partition, with each stream including a stream state. The control method includes: responsive to a shut-down initiating event, notifying the paging service partition to shut down, and determining whether a shared memory partition is currently active, and if so, signaling the hypervisor to complete paging activity for the active memory partition and waiting for its stream state to enter a suspended or a completed state before automatically shutting down the paging service partition.

摘要： Pretranslating input/output buffers in environments with multiple page sizes that include determining a pretranslation page size for an input/output buffer under an operating system that supports more than one memory page size, identifying pretranslation page frame numbers for the buffer in dependence upon the pretranslation page size, pretranslating the pretranslation page frame numbers to physical page numbers, and storing the physical page numbers in association with the pretranslation page size. Typical embodiments also include accessing the buffer, including translating a virtual memory address in the buffer to a physical memory address in dependence upon the physical page numbers and the pretranslation page size and accessing the physical memory of the buffer at the physical memory address.
