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.
