Abstract
According to embodiments of the disclosed subject matter, cores in a many-core processor may be periodically tested to obtain and/or refresh their dynamic profiles. The dynamic profile of a core may include information on its maximum operating frequency, power consumption, power leakage, functional correctness, and other parameters, as well as the trending information of these parameters. Once a dynamic profile has been created for each core, cores in a many-core processor may be grouped into different bins according to their characteristics. Based on dynamic profiles and the grouping information, the operating system (“OS”) or other software may allocate a task to those cores that are most suitable for the task. The interconnect fabric in the many-core processor may be reconfigured to ensure a high level of connectivity among the selected cores. Additionally, cores may be re-allocated and/or re-balanced to a task in response to changes in the environment.
