摘要： In a global shared memory (GSM) environment, a method provides local notification of completion of a global shared memory (GSM) operation processed by a first task executing at a local node of the distributed system. The system includes multiple nodes on which different tasks of a single job execute and perform GSM operations that are received from a second task via a via host fabric interface (HFI) and associated HFR window assigned to the first tasks. The local task initiates execution of a GSM operation on the local node. The task then monitors for and detects a completion of the execution of the GSM operation on the local node. When the task detects completion of the execution of the GSM operation, the task issues an internal notification to inform the locally-executing tasks of the completion of the GSM operation.

摘要： A method for providing global notification of completion of a global shared memory (GSM) operation during processing by a target task executing at a target node of a distributed system. The distributed system has at least one other node on which an initiating task that generated the GSM operation is homed. The target task receives the GSM operation from the initiating task, via a host fabric interface (HFI) window assigned to the target task. The task initiates execution of the GSM operation on the target node. The task detects completion of the execution of the GSM operation on the target node, and issues a global notification to at least the initiating task. The global notification indicates the completion of the execution of the GSM operation to one or more tasks of a single job distributed across multiple processing nodes.

摘要： Disclosed are a method and system for predicting future values of a target metric associated with a task executed on a computer system. The method comprises the steps of, over a given period of time, measuring at least one defined metric, transforming that measurement into a value for a predictor source metric, and using the value for the predictor source metric to obtain a predicted future value for said target metric. The preferred embodiment of this invention provides a flexible performance multi-predictor to solve the problem of providing accurate future behavior predictions for adaptive reconfiguration systems. The multi-predictor makes predictions about future workload characteristic by periodically reading available hardware counters. Also disclosed is a method and system for periodically reconfiguring an adaptive computer system by rescheduling tasks based on future behavior predictions.

摘要： The various aspects provide methods, servers, and systems for identifying independent portions of an HTML document so that the identified portions may be processed in parallel. The independent portions may be associated with an iframe tag having both the seamless and sandbox attributes. At runtime, a browser may detect the presence of both attributes, and process the contents of the iframe in parallel.

摘要： Mechanisms are provided for handling conflicts in a transactional memory system. The mechanisms execute threads in a data processing system in a first conflict resolution mode of operation in which threads execute conflicting transactional blocks speculatively. The mechanisms determine, for a transactional block, if the first conflict resolution mode of operation is to be transitioned to a second conflict resolution mode of operation in which threads accessing conflicting transactional blocks are executed serially and non-speculatively. Moreover, the mechanisms execute a thread that accesses the transactional block using the second conflict resolution mode of operation in response to the determination indicating that the first conflict resolution mode of operation is to be transitioned to the second conflict resolution mode of operation.

摘要： A method for combined static and dynamic compilation of program code to remove delinquent loads can include statically compiling source code into executable code with instrumented sections each being suspected of including a delinquent load, and also into a separate intermediate language representation with annotated portions each corresponding to one of the instrumented sections. The method also can include executing the instrumented sections repeatedly and monitoring cache misses for each execution. Finally, the method can include dynamically recompiling selected ones of the instrumented sections using corresponding ones of the annotated portions of the separate intermediate language representation only after a threshold number of executions of the selected ones of the instrumented sections, each recompilation include a pre-fetch directive at a pre-fetch distances tuned to avoid the delinquent load.

摘要： A method for optimizing distributed memory access using a protected page. The method includes generating library calls to perform array accesses. The method further includes generating a layout map or assisting the accesses. Each processor possesses a local copy of this map. The method proceeds by allocating arrays across the processors, such that each processor receives a local portion of the array. The method further proceeds by reserving the memory location immediately before the local address. Then, the method proceeds by placing the memory location address under access protection, such that a protected page is formed.

摘要： Systems and methods enable displaying a graphical representation of system resource usage in a resource utilization map to inform users about system resource utilization by applications and processes running on a computing device. Users may provide inputs to enable the system to adjust resource allocations based on user preferences. This may enable users to improve the overall operational performance of the device consistent with their current personal preferences by identifying applications or processes of most or least interest so the device processor to prioritize system resources accordingly. Some aspects transmit resource allocation data based on such user input to a central server to enable community based resource allocation schemes. Community based resource allocation schemes may be transmitted to computing devices for use as default or preliminary resource allocations for particular applications, websites or device operating states.
