SMT/ECO MODE BASED ON CACHE MISS RATE
First Claim
1. A computer implemented method for managing an execution mode for a parallel processor, the method comprising:
- identifying a first efficiency rate for a first contested resource of the parallel processor operating in a first operating mode;
responsive to identifying the first efficiency rate for the first contested resource, identifying whether the first efficiency rate for the contested resource of the parallel processor operating in the first operating mode exceeds a threshold; and
responsive to identifying that the efficiency rate for the contested resource exceeds the threshold, changing an operation of the parallel processor to a second operating mode.

Abstract
A computer implemented method for managing an execution mode for a parallel processor is provided. A monitor identifies a first efficiency rate for a first contested resource of the parallel processor operating in a first operating mode. Responsive to identifying the first efficiency rate for the first contested resource, the monitor identifies whether the first efficiency rate for the contested resource of the parallel processor operating in the first operating mode exceeds a threshold. Responsive to identifying that the efficiency rate for the contested resource exceeds the threshold, an operation of the parallel processor is changed to a second operating mode.

15. A data processing system comprising:
-
a storage having a computer program product encoded thereon for managing an execution mode for a parallel processor; a bus connecting the storage to a processor; and a processor, wherein the processor executes the computer program product;
to identify a first efficiency rate for a first contested resource of the parallel processor operating in a first operating mode;
responsive to identifying the first efficiency rate for the first contested resource, to identify whether the first efficiency rate for the contested resource of the parallel processor operating in the first operating mode exceeds a threshold; and
responsive to identifying that the efficiency rate for the contested resource exceeds the threshold, to change an operation of the parallel processor to a second operating mode. - View Dependent Claims (16, 17, 18, 19, 20, 21)
