1. A method for thread consolidation in a system that includes an operating system and a multi-core processing chip in communication with an accelerator chip, the method comprising:

  • running an application having software threads on the operating system;

    mapping the software threads to physical cores in the multi-core processing chip;

    identifying one or more idle hardware threads in the multi-core processing chip;

    identifying one or more idle accelerator units in the accelerator chip;

    executing the software threads on the physical cores and the accelerator unit;

    consolidating, by the controller module, the software threads executing on the physical cores, resulting in one or more idle physical cores and a consolidated physical core; and

    activating, by the controller module, a power savings mode for the one or more idle physical cores.
