Distributed computing feasibility in a non-dedicated homogeneous distributed system

Abstract: The authors address the feasibility of a nondedicated parallel processing environment, assuming workstation processes have preemptive priority over parallel tasks. They develop an analytical model to predict parallel job response times. The model provides insight into how significantly the workstation owner interference degrades parallel program performance. A new term, task ratio, which relates the parallel task demand to the mean service demand of nonparallel workstation processes, is introduced. It is proposed that the task ratio is a useful metric for determining how large the demand of a parallel applications must be in order to make efficient use of a nondedicated distributed system.

Automatic test system and method of distributed integrated service

Abstract: The invention discloses automatic test system and method of a distributed integrated service. The automatic test system comprises clients arranged in a distributed way, a dispatch server and testing subsystems and tests tested systems arranged in the distributed way, wherein the clients organize test items according to logical relation to generate test tasks, send the test tasks to the dispatch server after starting to test as well as receive and view test reports from the dispatch server; the dispatch server analyzes the test tasks, dispatches the test items according to the logical relation and distributes the task items to corresponding testing subsystems; and the testing subsystems analyze and execute the test items to test the tested systems, collect test item executing reports and report the test item executing reports to the dispatch server, and the dispatch server summarizes to generate the test task reports to be viewed by the clients. The invention supports the multi-service complex test scene and the execution of multiple test tasks, greatly expands the breadth and the depth of test and enhances the efficiency of the test.

Method and program product for costing and planning the re-hosting of computer-based applications

Abstract: A computer-implemented method and program product for estimating cost and/or time requirements for migrating an application from one platform to another. The method includes receiving identifications for tasks, receiving at least one assessment type selected for estimating cost and/or time requirement for migration, where the assessment type delineates a degree of accuracy for estimating the cost and/or time requirement for migration, correlating base costs and/or time requirements to the tasks identified, receiving identifications of attributes that affect base costs and/or time requirements, correlating cost and/or time factors to the tasks, a respective cost factor and/or time factor indicating an amount by which an attribute affects the respective base cost and/or time requirement for a task, and estimating cost and/or time requirements for each task, by applying the respective cost and/or time factors for each task to the respective base cost and/or base time requirements for each task.

Dynamic aircraft maintenance management system

Abstract: The present invention is a system (10) for enabling an operator to dynamically manage maintenance of an aircraft. The system (10) includes a program manager system (22), a tracking manager system (24) and a production manager system (26). The program manager system (22) is for extracting maintenance tasks from aircraft maintenance publications (14), and for guiding the formation of maintenance tasks groups. The tracking manager system (24) is for monitoring accumulated usage data of the aircraft, and for identifying maintenance due tasks and maintenance due task groups from the respective maintenance tasks and maintenance task groups for which a difference between the control point and the accumulated usage data is less than a user-defined critical value. The production manager system (26) is for generating and implementing a dynamic maintenance flow chart which details scheduling data for each individual task of the maintenance due tasks and maintenance due task groups.

Bayesian Methods for Intelligent Task Assignment in Crowdsourcing Systems

Abstract: In many decision-making scenarios, it is necessary to aggregate information from a number of different agents, be they people, sensors or computer systems. Each agent may have complementary analysis skills or access to different information, and their reliability may vary greatly. An example is using crowdsourcing to employ multiple human workers to perform analytical tasks. This chapter presents an information-theoretic approach to selecting informative decision-making agents, assigning them to specific tasks and combining their responses using a Bayesian method. For settings in which the agents are paid to undertake tasks, we introduce an automated algorithm for selecting a cohort of agents (workers) to complete informative tasks, hiring new members of the cohort and identifying those members whose services are no longer needed. We demonstrate empirically how our intelligent task assignment approach improves the accuracy of combined decisions while requiring fewer responses from the crowd.
