A lock / unlock mechanism to control concurrent access to objects in a multi-threaded computer processing system comprises two parts: a thread pointer (or thread identifier), and a one-bit flag called a "Bacon bit". Preferably, when an object is not locked (i.e., no thread has been granted access to the object), the thread identifier and Bacon bit are set to 0. When an object is locked by a particular thread (i.e., the thread has been granted access to the object), the thread identifier is set to a value that identifies the particular thread; if no other threads are waiting to lock the object, the Bacon bit is set to 0; however, if other threads are waiting to lock the object, the Bacon bit is set to "1', which indicates the there is a queue of waiting threads associated with the object. To lock an object, a single CompareAndSwap operation is preferably used, much like with spin-locks; if the lock is already held by another thread, enqueueing is handled in out-of-line code. To unlock an object, in the normal case, a single CompareAndSwap operation may be used. This single operation atomically tests that the current thread owns the lock, and that no other threads are waiting for the object (i.e., the Bacon bit is "0'). A global lock is preferably used to change the Bacon bit of the lock. This provides an lock / unlock mechanism which combines many of the desirable features of both spin locking and queued locking, and can be used as the basis for a very fast implementation of the synchronization facilities of the Java language.

Systems and methods for user interface (UI) flagging. The methods involve setting a first visual indicator on or adjacent to a first UI element of a UI when code that generates the first UI element has been added to an application or modified so as to change at least one functional characteristic of the first UI element. The methods also involve setting a second visual indicator on a first UI object of the application when code that generates the first UI object has been modified so as to remove a second UI element therefrom. The visual indicators are set by adding UI flagging code to the code that generates the first UI element and / or first UI object. Also, third visual indicators can be set on or adjacent to second UI objects that have “trails” to the first UI element and / or the first UI object.

A user interface (132)—be it graphical (GUI) or telephony (TUI) to an application (120) is defined by stored interface and feature description documents (122,124) written in XML and JavaScript, so that the user interface and changes thereto can be effected without access to source code. Interface description documents define the appearance and the behavior of the user interface toward the user, while feature description documents define the interaction of the user interface with the interfaced-to application, both in conformity with a user-interface object model (310). Stored connector object plug-ins (126) define connector objects for rendering elements of feature description documents, and stored layout object plug-ins (128) define layout objects for rendering elements of interface description documents of one or more interfaces.

A novel method for streaming multi-media content is disclosed. Multiple versions of model data tailored for different operating environments differentiated in accordance with value(s) of at least one operating characteristic of remote requesting client computer systems are stored in a multi-media content providing server.

The multi-media content player adaptively requests appropriate versions of selected ones of the model data, based at least in part on the determined operating characteristic value(s) of the at least one operating characteristic of the client computer system. In response, the providing server streams the requested versions of the requested model data to the multi-media content player for rendering. As a result, user experience at the client computer system is enhanced.

A real-time approach to detecting aberrant modes of system behavior induced by abnormal and unauthorized system activities indicative of abnormal activity of a software system is based on behavioral information obtained from a suitably instrumented computer program as it is executing. The theoretical foundation is founded on a study of the internal behavior of the software system. As a software system is executing, it expresses a set of its many functionalities as sequential events. Each of these functionalities has a characteristic set of modules that is executed to implement the functionality. These module sets execute with defined and measurable execution profiles among the program modules and within the execution paths of the individual modules, which change as the executed functionalities change. Over time, the normal behavior of the system will be defined by the boundary of the profiles. Abnormal activity of the system will result in behavior that is outside the normal activity of the system and thus result in a perturbation of the system in a manner outside the scope of the normal profiles. Such anomalies are detected by analysis and comparison of the profiles generated from an instrumented software system against a set of nominal execution profiles. Moreover, a method for reducing the amount of information necessary to understand the functional characteristics of an executing software system identifies the common sources of variation among the program instrumentation point frequencies and builds execution profiles based on a reduced set of virtual execution domains.

In the method for implementing the event transfer system of a real time operating system kernel, the task with the highest priority first obtains the event under the multi-tasking environment which requires real time characteristics. In the case of the multi-tasking environment in which the priority-based preemptive scheduling is adapted, if a plurality of tasks with respect to one event, call a kernel system function of receiving the event, the real time operating system kernel queues the tasks into the waiting-list of the event in the priority order. In this state, when the event is sent, the task having the highest priority in the waiting-list immediately obtains the event, is woken up and is resumed in its execution.

An apparatus for and method of enhancing reliability within a cluster lock processing system having a relatively large number of commodity cluster instruction processors which are managed by a cluster lock manager. Because the commodity processors have virtually no system viability features such as memory protection, failure recovery, etc., the cluster / lock processors assume the responsibility for providing these functions. The low cost of the commodity cluster instruction processors makes the system almost linearly scalable. The cluster / locking, caching, and mass storage accessing functions are fully integrated into a single hardware platform which performs the role of the master. Upon failure of this hardware platform, a second redundant hardware platform converts from slave to master role. The logic for the failure detection and role swapping is placed within software, which can run as an application under a commonly available operating system. Furthermore, the recovery is completely accomplished without assistance of the Host computer(s) or ultimate user(s) coupled via the Host computer(s).
