| 20100008515 | MULTIPLE ACOUSTIC THREAT ASSESSMENT SYSTEM - A system is provided for locating and identifying an acoustic event. An acoustic sensor having a pair of concentric opposing microphones at a fixed distance on a microphone axis is used to measure an acoustic intensity, from which a vector incorporating the acoustic event is identified. A second acoustic sensor or movement of the first acoustic sensor is used to provide a second vector incorporating the acoustic event. Combination of the first and the second vector locates the acoustic event in space. A command unit in communication with the acoustic sensors can be used for combining the vectors as well as comparing a signal spectra of the acoustic event to stored identified spectra to provide an identification of acoustic event. | 01-14-2010 |

| 20110239219 | PROTECTING SHARED RESOURCES USING SHARED MEMORY AND SOCKETS - Shared memory and sockets are used to protect shared resources in an environment where multiple operating systems execute concurrently on the same hardware. Rather than using spinlocks for serializing access to the shared resources, when a thread is unable to acquire a shared resource because that resource is already held by another thread, the thread that was unable to acquire the resource creates a socket with which it will wait to be notified that the shared resource has been released. The sockets may be network sockets or in-memory sockets that are accessible across the multiple operating systems; if sockets are not available in a particular implementation, communication technology that provides analogous services between operating systems may be used instead. In an optional aspect, fault tolerance is provided to address socket failures, in which case one or more threads may fall back (at least temporarily) to using spinlocks. As another option, a locking service may execute on each operating system to provide a programming interface through which threads can invoke operations for holding and releasing the lock. | 09-29-2011 |

| 20090063594 | COMPUTER SYSTEM MEMORY MANAGEMENT - The number of CPU cycles required to reclaim object memory space in a memory management process is reduced by using a two phase approach. A data structure exists for each object that is to be loaded into object memory space. One part of the data structure is the object definition. The other part is a MM (Memory Management) immunity annotation or value that controls the frequency with which the object must actually be examined to determine if it is suitable for reclamation. On each iteration of the memory management process, the object's MM immunity value is tested to determine whether it is greater than a predetermined threshold. If greater than the threshold, the value is decremented, but the object is not actually examined for its suitability for removal. If the value equals the threshold, the object itself is examined. If it is found to be suitable, it is removed to reclaim the object memory space it previously occupied, If it is actually examined but is found not to be suitable for removal, the MM immunity value is reset to its original value or is otherwise adjusted to prevent examination of the object for a certain number of future iterations of the memory management process. | 03-05-2009 |

| 20090119668 | DYNAMIC FEASIBILITY ANALYSIS FOR EVENT BASED PROGRAMMING - Embodiments of the present invention provide a method, system and computer program product for dynamic feasibility analysis of event-driven program code. In an embodiment of the invention, a method for a dynamic feasibility analysis of event-driven program code can be provided. The method can include loading multiple different tasks associated with different registered events in event-driven program code of an event-driven application, reducing overlapping ones of the registered events for different ones of the tasks to a single task of the overlapping events to produce a reduced set of tasks and corresponding events, ordering the corresponding events of the reduced set of tasks and grouping the corresponding events by time slice for the event-driven application, and reporting whether or not adding a new event to a particular time slice for the event-driven application results in a depth of events in the particular time slice exceeding a capacity of the particular time slice rendering the event-driven application infeasible. | 05-07-2009 |

| 20090031292 | COPY-ON-WRITE OPTIMIZATION OF IMMUTABLE OBJECTS FOR OBJECT ORIENTED LANGUAGES - A computer implemented method, apparatus, and computer program product for copy-on-write optimization of immutable objects. An immutable object is marked as read-only to form a read-only object. The read-only object is formed to delay copying of the immutable object until a runtime determination is made that a write to the immutable object will be made. In response to an attempt to write to the read-only object, an internal value of the read-only object is copied to read-and-write storage using runtime information to form a writable copy of the read-only object. A set of references for the read-only object is updated to point to the writable copy of the read-only object. Delaying copying of the immutable object optimizes a copy-on-write of the immutable object. | 01-29-2009 |
| 20090077355 | INSTRUCTION EXPLOITATION THROUGH LOADER LATE FIX UP - A method, computer program product, and data processing system for substituting a candidate instruction in application code being loaded during load time. Responsive to identifying the candidate instruction, a determination is made whether a hardware facility of the data processing system is present to execute the candidate instruction. If the hardware facility is absent from the data processing system, the candidate instruction is substituted with a second set of instructions. | 03-19-2009 |
| 20090077356 | LOAD TIME INSTRUCTION SUBSTITUTION - A method, computer program product, and data processing system for substituting a candidate instruction in application code being loaded during load time. Responsive to identifying the candidate instruction, a determination is made whether a hardware facility of the data processing system is present to execute the candidate instruction. If the hardware facility is absent from the data processing system, the candidate instruction is substituted with a second set of instructions. | 03-19-2009 |
| 20090158288 | METHOD AND APPARATUS FOR MANAGING SYSTEM RESOURCES - A computer implemented method, apparatus, and computer usable program product for system management. The process schedules a set of application tasks to form a schedule of tasks in response to receiving the set of application tasks from a registration module. The process then performs a feasibility analysis on the schedule of tasks to identify periods of decreased system activity. Thereafter, the process schedules a set of system management tasks during the periods of decreased system activity to form a prioritized schedule of tasks. | 06-18-2009 |

| 20110154304 | DETERMINING COMPILER EFFICIENCY - There is provided a computer implemented method for determining the efficiency of a runtime compiler. A set of execution times representing the time taken for program code to perform a set task after two or more runtime compilations is recorded. A first metric as the difference between the first execution time and the last execution time of the set of execution times, a second metric as the average throughput improvement from the set of execution times, and a third metric as the time taken for the compiler to achieve the maximum throughput from the set of execution times is calculated. Finally, an efficiency metric is calculated using the first, second and third metrics to determine the efficiency of the compiler. | 06-23-2011 |
