TL;DR: In this article, a computer system for distributed processing, particularly of digital audio data, is described, which includes means for assigning to a particular processor a specific processing task or tasks, as well as a means for assign additional specific processing tasks to that same processor to maximize its use.
Abstract: A computer system for performing distributed processing, particularly of digital audio data, is disclosed. The system has a number of digital signal processors linked to a host computer through a time division multiplex bus. The system includes means for assigning to a particular processor a specific processing task or tasks, as well as a means for assigning additional specific processing tasks to that same processor to maximize its use. When the processor performing a specific processing task has reached its capacity, the system assigns a new processor to perform that task. To enhance the efficiency of the processor to perform the specific processing task, the processor cyclically runs a specific set of instructions for performing that specific processing task, and waits for the system to send it digital data to be processed.

TL;DR: The present study examined the effects of different secondary tasks on performance of three psychometric visuospatial tasks and proposed that, when applied to the assessment of central executive involvement, the prevalent simple dual-task logic does not always apply.
Abstract: The dual-task paradigm has been used to examine the role of the central executive in various cognitive tasks. In these studies, performance decrements in primary cognitive tasks performed concurrently with secondary executive tasks have been interpreted as evidence for the involvement of the central executive in those primary tasks. In the present study, we examined the effects of different secondary tasks on performance of three psychometric visuospatial tasks. The decrement in performance of these tasks when they were paired with secondary executive tasks was smallest for the psychometric task considered to most heavily involve the central executive and largest for the task considered least demanding of executive mechanisms. We propose that, when applied to the assessment of central executive involvement, the prevalent simple dual-task logic does not always apply. Special conditions that limit the application of the dual-task methodology include two inherently related factors—a response selection bottleneck and a strategic tradeoff between primary and secondary tasks.

TL;DR: In this paper, a system and method for parallel execution of logic programs on a computer network comprising two or more local-memory processors includes a logic program interpreter resident on all processors in the system.
Abstract: A system and method for parallel execution of logic programs on a computer network comprising two or more local-memory processors includes a logic program interpreter resident on all processors in the system. The interpreter commences execution of a logic program on one processor and, based on the results of its initial execution, generates lists of parallel-executable tasks and distributes them to other processors in the network to which it is coupled. Each processor which receives parallel tasks likewise commences execution, identification of parallel sub-tasks, and further distribution. When there are no parallel tasks at a processor or other processors available for further distributions, the task is executed sequentially and all execution results are returned to the processor which distributed the tasks executed.

TL;DR: In this paper, a user can call into an externally-facing interface of the control environment, the call being analyzed to determine actions to be performed in the data environment, and a workflow can be instantiated that includes tasks necessary to perform the action.
Abstract: Aspects of a data environment, such as the creation, provisioning, and management of data stores and instances, are managed using a separate control environment. A user can call into an externally-facing interface of the control environment, the call being analyzed to determine actions to be performed in the data environment. A monitoring component of the control plane also can periodically communicate with the data environment to determine any necessary actions to be performed, such as to recover from faults or events in the data environment. A workflow can be instantiated that includes tasks necessary to perform the action. For each task, state information can be passed to a component in the data environment operable to perform the task, until all tasks for an action are completed. Data in the data environment can be accessed directly using an externally-facing interface of the data environment, without accessing the control plane.

TL;DR: In this article, a tunable operating system in a multiprogrammed data processing system prevents lockout of I/O bound tasks by CPU bound tasks of high priority by assigning a plurality of time-slice values, preferably two, when tasks are dispatched.
Abstract: A tunable operating system in a multiprogrammed data processing system prevents lockout of I/O bound tasks of low priority by CPU bound tasks of high priority. A range signal in the master control block and a range divider signal in each task control block together define a queue subset for each task. The queue subsets for different tasks are overlapped by at least one queue, and preferably by at least three queues. A plurality of time-slice values, preferably two, are assigned when tasks are dispatched; the time-slice values are assigned with respect to the task range divider signal and therefore are not fixed with respect to each queue. The invention permits the weight given to the user-set task priority and to the priority based on recent task behavior to be varied as desired. The range value, the divider values, and the time-slice values are variable to permit tuning of the operating system.
