Task-Based Performance Resource Management of Computer Systems

摘要

Execution of a plurality of tasks by a processor system are monitored. Based on this monitoring, tasks requiring adjustment of performance resources are identified by calculating at least one of a progress error or a progress limit error for each task. Thereafter, performance resources of the processor system allocated to each identified task are adjusted. Such adjustment can comprise: adjusting a clock rate of at least one processor in the processor system executing the task, adjusting an amount of cache and/or buffers to be utilized by the task, and/or adjusting an amount of input/output (I/O) bandwidth to be utilized by the task. Related systems, apparatus, methods and articles are also described.

1. A method for implementation by one or more data processors comprising:
monitoring execution of a plurality of tasks by a processor system, the monitoring being based at least in on an amount of work completed by a corresponding task, the amount of work being derived from at least one of: data transferred when executing the task, a number of processor instructions when executing the task, a number of processor cycles when executing the task, or an execution time for the task; identifying, based on the monitoring, tasks requiring adjustment of performance resources by calculating at least one of a progress error and a progress limit error for each task; and adjusting performance resources of the processor system allocated to each identified task; wherein adjusting the performance resources comprise one or more of:
adjusting a clock rate of at least one processor in the processor system executing the task;adjusting an amount of cache and/or buffers to be utilized by the task; oradjusting an amount of input/output (I/O) bandwidth to be utilized by the task.
