摘要： According to a system and method for composing a virtual disk for a virtual desktop, the virtual desktop is booted from a virtual disk comprised of a base disk image and a user delta disk image that receives all disk writes to the virtual disk. Disk space is allocated on the virtual disk for a file associated with a selected application to be provided to a user of the virtual desktop. Then the virtual desktop is recomposed offline by linking the base disk image, an application delta disk image including the file associated with the selected application, and the user delta disk image. The recomposing includes modifying meta data of the application delta disk and the user delta disk so that the file associated with the selected application is mapped to the disk space previously allocated.

摘要： A plurality of Guest cells of Guest instructions are provided with corresponding Host cells for emulating Guest instructions, each Guest instruction having a Guest cell corresponding to a Host cell. Each of the Host cells are initialized with an initialization routine for discovering a corresponding semantic routine for emulating the Guest instruction. When an instruction is to be emulated for the first time, the initialization routine patches itself with the discovered semantic routine such that subsequent emulation of the Guest instruction can be directly performed.

摘要： A method and apparatus for offloading processing tasks from a first computing environment to a second computing environment, such as from a first interpreter emulation environment to a second native operating system within which the interpreter is running. The offloading method uses memory queues in the first computing environment that are accessible by the first computing environment and one or more offload engines residing in the second computing environment. Using the queues, the first computing environment can allocate and queue a control block for access by a corresponding offload engine. Once the offload engine dequeues the control block and performs the processing task in the control block, the control block is returned for interrogation into the success or failure of the requested processing task. The offload engine is a separate process in a separate computing environment, and does not execute as part of any portion of the first computing environment.

摘要： Executing programs coded in an instruction set of a first computer on a computer of a second, different architecture. An operating system maintains an association between each one of a set of concurrent threads and a set of computer resources of the thread's context. Without modifying a pre-existing operating system of the computer, an entry exception is establishing to be raised on each entry to the operating system at a specified entry point or on a specified condition. The entry exception has an associated entry handler programmed to save a context of an interrupted thread and modify the thread context before delivering the modified context to the operating system. A resumption exception is established to be raised on each resumption from the operating system complementary to one of the specified entries. The resumption exception has an associated exit handler programmed to restore the context saved by a corresponding execution of the entry handler. The entry exception, exit exception, entry handler, and exit handler are cooperatively designed to maintain an association between a one of the threads and an extended context of the thread through a context change induced by the operating system, the extended context including resources of the computer associated with the thread beyond those resources whose association with the thread is maintained by the operating system.

摘要： Approaches for emulating an operating system. A method includes executing a first operating system (OS) on an instruction processor. The first OS includes instructions of a first instruction set that are native to the instruction processor. A second OS is emulated on the first OS and includes instructions of a second instruction set that are not native to the instruction processor. An emulated transfer-of-control instruction is determined during emulation of the second OS to target either instructions of the first set or the second set. In response to determining that instructions of the first set are targeted, control is transferred to the targeted instructions of the first set on the instruction processor. In response to determining that instructions of the second set are targeted, the targeted instructions of the second set are retrieved and emulated.
