Abstract: A system for preparing a first multimedia stream, for use with an environment comprising a repository for storing a plurality of tracks, wherein each track is associated with at least one second multimedia stream. A track comprises a single type of data (e.g. audio, video etc.). The system comprises means for receiving a request comprising an associated parameter (e.g. position parameter); means for determining at least two of the plurality of tracks associated with the parameter (e.g. wherein the at least two tracks have associated information that matches the position parameter); and means, responsive to the determining means, for collating the determined at least two tracks in order to generate the first multimedia stream.

Abstract: An optimizer mechanism to increase battery length for mobile devices is provided. An operational state of a data processing system, e.g., a mobile device, is adjusted so as to achieve a target time period of operation when the data processing system is using a depleting power supply. A predicted power consumption of individual processes executing on the data processing system is determined and a remaining amount of power that the depleting power supply can provide is also determined. A subset of processes whose execution can be suspended is determined so that the data processing system can operate for the target period of time based on the predicted power consumption of the individual processes and the amount of power that the depleting power supply can provide. The identified subset of processes are placed in a suspended execution state.

Abstract: A mechanism for broadcasting instructions/data to a plurality of processors in a multiprocessor device via aliasing is provided. In order to broadcast data to a plurality of processors, a control processor writes to the registers that store the identifiers of the processors and sets two or more of these registers to a same value. The control processor may write the desired data/instructions to be broadcast to a portion of memory corresponding to the starting address associated with the processor identifier of the two or more processors. When the two or more processors look for a starting address of their local store from which to read, the two or more processors will identify the same starting address, essentially aliasing the memory region. The two or more processors will read the instructions/data from the same aliased memory region starting at the identified starting address and process the same instructions/data.

Abstract: Scheduling of parallel processing for regionally-constrained object placement selects between different balancing schemes. For a small number of movebounds, computations are assigned by balancing the placeable objects. For a small number of objects per movebound, computations are assigned by balancing the movebounds. If there are large numbers of movebounds and objects per movebound, both objects and movebounds are balanced amongst the processors. For object balancing, movebounds are assigned to a processor until an amortized number of objects for the processor exceeds a first limit above an ideal number, or the next movebound would raise the amortized number of objects above a second, greater limit. For object and movebound balancing, movebounds are sorted into descending order, then assigned in the descending order to host processors in successive rounds while reversing the processor order after each round. The invention provides a schedule in polynomial-time while retaining high quality of results.

Abstract: Mechanisms for distributing workload items to a plurality of dispatchers are provided. Each dispatcher is associated with a different computing system of a plurality of computing systems and workload items comprise workload items of a plurality of different workload types. A capacity value for each combination of workload type and computing system is obtained. For each combination of workload type and computing system, a queue length of a dispatcher associated with the corresponding computing system is obtained. For each combination of workload type and computing system, a dispatcher's relative share of incoming workloads is computed based on the queue length for the dispatcher associated with the computing system. In addition, incoming workload items are routed to a dispatcher, in the plurality of dispatchers, based on the calculated dispatcher's relative share for the dispatcher.

Abstract: Mechanisms are provided for refining an abstraction of a netlist for verification or synthesis of an integrated circuit design. The mechanisms receive an abstracted netlist corresponding to an original netlist of the integrated circuit design. The mechanisms determine elements already present in the abstracted netlist and refine the abstracted netlist by expanding the abstracted netlist to include additional elements that are correlated with the elements already present in the abstracted netlist to thereby generate a refined abstracted netlist. In addition, the mechanisms utilize the refined abstracted netlist to perform at least one of verification or synthesis of the integrated circuit design.

Abstract: Mechanisms for providing a memory region/memory window (MR/MW) access notification on a system area network are provided. Whenever a previously allocated MR/MW is accessed, such as via a remote direct memory access (RDMA) read/write operation, a notification of the access is generated and written to a queue data structure associated with the MR/MW. In one illustrative embodiment, this queue data structure may be a MR/MW event queue (EQ) data structure that is created and used for all consumer processes and all MR/MWs. In other illustrative embodiments, the EQ is associated with a protection domain. In yet another illustrative embodiment, an event record may be posted to an asynchronous event handler in response to the accessing of the MR/MW. In another illustrative embodiment, a previously posted queue element may be used to generate a completion queue element in response to the accessing of the MR/MW.

Abstract: Mechanisms are provided for performing setup operations for receiving a different amount of data while processors are performing message passing interface (MPI) tasks. Mechanisms for adjusting the balance of processing workloads of the processors are provided so us to minimize wait periods for waiting for all of the processors to call a synchronization operation. An MPI load balancing controller maintains a history that provides a profile of the tasks with regard to their calls to synchronization operations. From this information, it can be determined which processors should have their processing loads lightened and which processors are able to handle additional processing loads without significantly negatively affecting the overall operation of the parallel execution system. As a result, setup operations may be performed while processors are performing MPI tasks to prepare for receiving different sized portions of data in a subsequent computation cycle based on the history.

Abstract: Mechanisms are provided for managing email disk usage based on user specified conditions. An incoming email for a user is scanned for email expressions. A determination is made as to whether one of the email expressions matches one of a number of listed expressions forming a matched expression. Responsive to a presence of a matched expression, a determination is made as to whether a first threshold associated with the matched expression is met or exceeded. Responsive to the first threshold being met or exceeded, a notification is sent to the user of the first threshold being met.

Abstract: Methods, systems, and media are disclosed for a computer-implemented method for improved messaging between devices, which are local or remote to each other. One example embodiment includes a first device, having a first set of messaging preferences, receiving a second set of messaging preferences from a second device, such as a computer having instant messaging capabilities, in communication with the first device. Further, the example embodiment includes comparing the sets of messaging preferences to yield results showing if any conflicting messaging preferences exist between the devices. If conflicting messaging preferences exist, then the devices may negotiate in order to remove such conflicting messaging preferences. Further still, the example embodiment includes determining whether to commence the messaging based on the existence of any conflicting messaging preferences and by enforcing the possibly re-configured messaging preferences during a messaging session.

Abstract: A mechanism programming a direct memory access engine operating as a multithreaded processor is provided. A plurality of programs is received from a host processor in a local memory associated with the direct memory access engine. A request is received in the direct memory access engine from the host processor indicating that the plurality of programs located in the local memory is to be executed. The direct memory access engine executes two or more of the plurality of programs without intervention by a host processor. As each of the two or more of the plurality of programs completes execution, the direct memory access engine sends a completion notification to the host processor that indicates that the program has completed execution.

Abstract: A method for performing a regression test on a software application is proposed. The regression test involves the execution of a subset of selected test cases on the software application (among all the ones being available). In the proposed solution, the selection of the test cases to be regressed is performed according to an effectiveness-based criterion. For this purpose, an effectiveness index of each test case is calculated according to its results being obtained during previous executions of the test case; preferably, the effectiveness index is based on the frequency of negative results of the test case (and secondarily on their variability and recency). The test cases whose effectiveness indexes reach a predefined threshold are then selected for running the regression test (on the assumption that they should be more effective in detecting errors of the software application).

Abstract: Systems for detecting Nagling on a TCP network connection are disclosed. Embodiments may generally include a system with a Nagle detection threshold determiner for determining a Nagle detection threshold based on the network connection. The system may also generally include a Nagle detection module in communication with the Nagle detection threshold determiner for observing a small segment at a second time following an acknowledgement indicative of a Nagling condition at a first time, wherein the Nagle detection module also may detect a Nagling condition if the difference between the second time and the first time is less than or equal to the Nagle detection threshold. The system may be a receiver computer or a network computer. The system may also generate and transmit a notification of the Nagling condition, increment a Nagle monitor counter, or save an indication of the Nagling condition in a log.

Abstract: Some embodiments comprise a method for selecting data to be transferred to a storage space of virtual memory and include identifying a set of data and determining subsets. Determining subsets may allow for delays before transferring the subsets and allow access to memory of the subsets during the delays. Accesses during the delays may enable embodiments to select other data to be transferred to the storage space and prevent transference of the accessed data. Other embodiments comprise apparatuses that have a paging space, a page identifier, and a page transferrer to transfer pages to the paging space after a delay. The delay may prevent a number of pages from being transferred to the paging space, such as for pages that were accessed during the delay.

Abstract: Mechanisms for instantiating an interface or abstract class in application code are provided. An object-oriented programming language is extended such that interfaces and abstract classes can be instantiated in application code without a concrete class specified. Metadata is defined which maps each interface or abstract class instantiation in the application code to a concrete class to be used either by the compiler at build time, or the virtual machine at runtime. Once the appropriate concrete class is determined from the metadata, the class is instantiated with a conventional class loader. The metadata may be provided, for example, as a separate file, such as a markup language file, defined with a virtual machine switch, as annotations in the application code, or the like.
