摘要： Techniques are described for optimizing memory management in a processor system. The techniques may be implemented on processors that include on-chip performance monitoring and on systems where an external performance monitor is coupled to a processor. Processors that include a Performance Monitoring Unit (PMU) are examples. The PMU may store data on read and write cache misses, as well as data on translation lookaside buffer (TLB) misses. The data from the PMU is used to determine if any memory regions within a memory heap are delinquent memory regions, i.e., regions exhibiting high numbers of memory problems or stalls. If delinquent memory regions are found, the memory manager, such as a garbage collection routine, can efficiently optimize memory performance as well as the mutators performance by improving the layout of objects in the heap. In this way, memory management routines may be focused based on dynamic and real-time memory performance data.

摘要： Provided is a method, system, and program for coordinating access to memory locations for hardware transactional memory transactions and software transactional memory transactions. A hardware transaction executing in hardware transactional memory initiates a request to access a memory location. A fault is returned to the hardware transaction request in response to an operation by one software transaction executing in a software transactional memory.

摘要： A method is disclosed for searching for text passages in text documents. The method uses computerized prediction-based and ontology-based semantic language processing. Both the text passages that are to be located, as well as the text of the documents that are searched, are transformed on the basis of surface-syntactic and deep-syntactic information to generate a semantic network structure. The semantic network structure is linguistically processed based on information about other parts of the semantic network structure in order to improve the accuracy of the semantic network structure. Nodes in the semantic network structure are classified by linking the nodes in the semantic network structure to nodes in a pre-existing ontological network structure representing concepts in a language.

摘要： Methods and apparatus to insert prefetch instructions based on garbage collector analysis and compiler analysis are disclosed. In an example method, one or more batches of samples associated with cache misses from a performance monitoring unit in a processor system are received. One or more samples from the one or more batches of samples based on delinquent information are selected. A performance impact indicator associated with the one or more samples is generated. Based on the performance indicator, at least one of a garbage collector analysis and a compiler analysis is initiated to identify one or more delinquent paths. Based on the at least one of the garbage collector analysis and the compiler analysis, one or more prefetch points to insert prefetch instructions are identified.

摘要： A system for treating an aneurysm in a vessel includes a delivery device having a delivery portion suitable for delivery of embolic material. The delivery device is placed in a neck of the aneurysm and an expandable member is placed proximate the neck. The expandable member is expanded to overlie substantially the entire neck. Embolic material is delivered to the aneurysm with a delivery device. The expandable member is held over the neck to inhibit movement of the embolic material out of the aneurysm. Blood is allowed to flow out of the aneurysm, past the neck of the aneurysm, and through the vessel while the expandable member is held over the neck of the aneurysm.

摘要： A method of preventing vibration loosening of a clamping screw 26 of a circuit protection apparatus 10 is provided. The circuit protection apparatus 10 has a conductor receiving member 28 including a conductor receiving opening 40 for receiving an electrical conductor 46 therein. The conductor receiving member 28 has an aperture 42 extending from a surface 50 thereof into communication with the conductor receiving opening 40. An overall extent of the aperture 42 includes threads. The method provides a clamping screw 26 having a threaded shaft 50. The threaded shaft 50 has a surface feature 52 in the threads thereof near an end 54 of the shaft. The clamping screw 26 is inserted into the threaded aperture 42 until the surface feature 52 is in interference engagement with threads of the threaded aperture to hold the clamping screw in the threaded aperture, with the end 54 of the shaft being disposed to permit access to the conductor receiving opening 40 such that the clamping screw need not be backed-out from the threaded aperture to provide access to the conductor receiving opening 40.
