摘要： A system, method and computer program product for atomically moving a shared list element from a first list location to a second list location includes inserting a placeholder element at the second list location to signify to readers that a move operation is underway, removing the shared list element from the first list location, re-identifying the list element to reflect its move from the first list location to the second list location, inserting it at the second list location and unlinking the placeholder element. A deferred removal of the placeholder element is performed following a period in which readers can no longer maintain references thereto. A method, system and computer program product are additionally provided for performing a lookup of a target list element that is subject to being atomically moved from a first list to a second list.

摘要： A method and apparatus for restricting access of an application to computer hardware. The apparatus includes both an authentication module and a validation module. The authentication module is within the trusted firmware layer. The purpose of the authentication module is to verify a cryptographic key presented by an application. The validation module is responsive to the authentication module and limits access of the application to the computer hardware. The authentication modules may be implemented in software through a firmware call, or through a hardware register of the computer.

摘要： A virtualized system including a processing sub-system including a plurality of partitions and operating systems and a virtualization layer, each partition running its own operating system and having assigned its own partition ID, and an I/O emulation entity connected to the processing sub-system through a bus and connected to a network to which is connected at least one computer that hosts at least one remote I/O peripheral, the I/O emulation entity being adapted to execute an I/O-emulation transaction for any of the operating systems in accordance with that operating system's partition-ID.
