Mechanism for on-line prediction of future performance measurements in a computer system

A method of periodically reconfiguring an adaptive computer system based on future behavior predictions, comprising the steps:

• for each of a group of tasks, assigning a dynamic priority to the task based on a history table based prediction of a future value for a characteristic associated with the task;
• and
• at defined times, selecting from said group the task having the highest dynamic priority to be executed by the computer system.

Apparatus for periodically reconfiguring an adaptive computer system based on future behavior predictions, comprising:

• a predictor for assigning a dynamic priority to each of a group of tasks based on a history table based prediction of a future value for a characteristic associated with the task;
• and
• a scheduler for selecting, at defined times, from said group the task having the highest dynamic priority to be executed by the computer system.

A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for periodically reconfiguring an adaptive computer system based on future behavior predictions, said method steps comprising:

• for each of a group of tasks, assigning a dynamic priority to the task based on a history table based prediction of a future value for a characteristic associated with the task;
• and
• at defined times, selecting from said group the task having the highest dynamic priority to be executed by the computer system.
