Abstract (en)
[origin: WO2011120019A2] 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.
