Mechanism to control and use window events among applications in concurrent computing

Abstract: A new application sharing technology that enables sharing of many single-user non-modified applications between two or more workstations. It provides concurrent sharing of existing multiple applications with no change in a distributed environment. It permits real-time sharing of distributed applications based on a fundamental window hierarchical mapping and user interactions. Control is centralized but the data and program are replicated. It is event driven with agent assistance. The new event capturing capability is automatically triggered by user interactions on entering/leaving the shared window. The event capturing capability starts when the user moves the pointer into the shared windows. The event capturing ends when the user moves the pointer out of the shared windows. The new multicasting scope is defined in a shared window hierarchy data array. This global data array is dynamically created at run time on an as-needed basis. Because this mechanism only processes user input events such as mouse, keyboard or cursor movement (commands), no output graphic data transmission across the network is required. Therefore, this approach is extremely light-weight and provides secure transmission without requiring intensive encryption. Because it is not using pseudo server interception, this approach can support DHA 3-D rendering. Also, the agent can dynamically mediate resources and normalize environment differences. This permits real-time sharing of 3-D, graphic and DHA (direct hardware access) applications. DHA permits the application to bypass the windowing server to render graphics on display. Moreover, because it is extremely light-weight, high network bandwidth is not required.

Accelerating multimedia with enhanced microprocessors

Abstract: A minimalistic set of multimedia introductions introduced into PA-RISC microprocessors implements SUID-MIMD parallelism with insignificant changes to the underlying microprocessor. Thus, a software video decoder attains MPEG video and audio decompression and playback at real-time rates of 30 frames per second, on an entry-level workstation. Our general-purpose parallel subword instructions can accelerate a variety of multimedia programs. >

Computer windows management system and method for simulating off-screen document storage and retrieval

Abstract: A novel computer display interface which simulates familiar document handling activities based upon a unique display metaphor representative of a standard office filing system and work area of a desk. The display system includes multi-windows which are displayed in a central screen area designated for just active computer windows. The interface further includes designating the edge areas of the screen for displaying window tabs of inactive windows. The window tabs are arranged in a way to simulate an integrated filing system, and to provide a convenient method of organizing and viewing computer files.

Weak nonlinearities: a new route to optical quantum computation

Abstract: Quantum information processing (QIP) offers the promise of being able to do things that we cannot do with conventional technology. Here we present a new route for distributed optical QIP, based on generalized quantum non-demolition measurements, providing a unified approach for quantum communication and computing. Interactions between photons are generated using weak nonlinearities and intense laser fields—the use of such fields provides for robust distribution of quantum information. Our approach only requires a practical set of resources, and it uses these very efficiently. Thus it promises to be extremely useful for the first quantum technologies, based on scarce resources. Furthermore, in the longer term this approach provides both options and scalability for efficient many-qubit QIP.
