摘要： An apparatus and method is described herein for adaptive thread scheduling in a transactional memory environment. A number of conflicts in a thread over time are tracked. And if the conflicts exceed a threshold, the thread may be delayed (adaptively scheduled) to avoid conflicts between competing threads. Moreover, a more complex version may track a number of transaction aborts within a first thread that are caused by a second thread over a period, as well as a total number of transactions executed by the first thread over the period. From the tracking, a conflict ratio is determined for the first thread with regard to the second thread. And when the first thread is to be scheduled, it may be delayed if the second thread is running and the conflict ratio is over a conflict ratio threshold.

摘要： Disclosed are a method, apparatus and system for managing a shared heap and compiled code cache in a managed runtime environment. Based on feedback generated during runtime, a runtime storage manager dynamically allocates storage space, from a shared storage region, between a compiled code cache and a heap. For at least one embodiment, the size of the shared storage region may be increased if a growth need is identified for both the compiled code cache and the heap during a single iteration of runtime storage manager processing.

摘要： A multi-user collaborative system in which the contents as well as the current status of other user activity of a shared structured data object representing one or more related structured data objects in the form of data entries can be concurrently accessed by different users respectively at different workstations connected to a common link. The WYSIWIS user interface representation of the shared structured data object includes an ordered listing of such entries that are maintained by the structured data object and various attributes of each listed entry, inter alia, the type and class of entry; the revision number of the shared structured data object; the number of pages and revision number of each structured data object entry; the date of creation and last revision of each such entry; whether an entry can be accessed by a user and, if not, who has prevented such access to prevent concurrent editing; whether a local instance of an entry is present on a user's system; and a provision for miscellaneous notes or comments relative to each entry for view by other users. Means is provided for maintaining current information relative to the shared structured object and its entries on a user initiated demand updated basis invoked by a user operation, which operation requires updated information to properly implement the operation.

摘要： One embodiment of the present invention provides a system for allocating storage space for objects within a persistent object system. The persistent object system includes an object heap that is organized into a young generation region and an old generation region. The system uses the young generation region for newly created objects and uses the old generation region for objects that have not been removed by several garbage collection cycles. The system allocates storage space for new (transient) objects in the young generation region of the object heap. Periodically, the system copies the transient objects from the object heap to a stable store to form a checkpoint of the system state. Transient objects become persistent objects when they are copied to the stable store. Persistent objects are removed from the object heap when the system is stopped and when room is needed in the object heap for additional objects. When a persistent object that has been removed is referenced during execution of a computer program, the system faults the persistent object directly into the old generation region of the object heap from the stable store.

摘要： A method and apparatus for generating a platform-standard object file containing machine-independent abstract code. Source code which defines a procedure is convened into abstract code which makes no assumptions about the platform on which the procedure will be executed. An abstract code platform-standard object file is generated based on the abstract code. The abstract code platform-standard object file includes a list of definitions of any global variables defined in the abstract code, a list of symbol references indicative of any external variables or external procedures referenced in the abstract code, a sequence of machine instructions for calling an execution routine when a client calls the procedure, and the abstract code which defines the procedure. The abstract code is preferably compressed before it is stored in the abstract code platform-standard object file. When a program including the abstract code platform-standard object file is executed, it is dynamically linked to the execution routine. When the procedure is called, the execution routine is invoked. The execution routine executes the procedure by interpreting the abstract code or generating machine-code responsive to the abstract code. The execution routine may be an execution control unit which selects between various execution techniques based on runtime factors, such as the frequency with which the procedure is called.

摘要： The present invention uses feedback to determine the size of an object cache. The size of the cache, (i.e., its budget), varies and is determined based on feedback from the persistent object system. Persistent objects are evicted from the cache if the storage for persistent objects exceeds the budget. If the storage is less than the budget then persistent objects in the heap are retained while new persistent objects are added to the cache.

摘要： A system for providing a user or agent control over functions defined by an object in a target application. The object is a new type of object called a controllable object, which publishes its functions and for use by a control application. When the target application execution is commenced, it generates predefined controllable objects, and then execution of the control application is commenced. The control application obtains a handle on the controllable object, and then is able to set any of a number of predefined values in the controllable object, such as individual variables or parameters, ranges of values, a list of choices from which the user can select, and others. In this way, the user can manipulate, test and optimize the target application even during its execution, by virtue of the pre-programmed controllable object functions. With a standard data structure for the data items involved and a standard controllable object set of functions, a generic control program can be used to interact with any new target application utilizing the standards, and the target application and control program do not need any other information about one another in advance, providing portable test interaction with any target application using a single control application.
