Abstract:
In a multi-processor multi-threaded computer system, resources are dynamically assigned during program operation to either threads or processors in such a manner that resource usage is maximized. In one embodiment, the choice of whether to assign resources to threads or processors is dependent on the number of threads versus the number of processors. In another embodiment, when the system is operating in one assignment mode, the amount of wasted resources is measured and when this measured amount exceeds a predetermined threshold based on the maximum resources that could be wasted were the system operating in the other assignment mode, the assignment is switched to the other assignment mode.
