RUNTIME OPTIMIZATION OF MULTI CORE SYSTEM DESIGNS FOR INCREASED OPERATING LIFE AND MAXIMIZED PERFORMANCE

摘要

Aspects include computing devices systems and methods for adjusting the assignment of tasks to processor cores in a multi core processing system to increase operating life and maximize device performance by wear leveling the processor cores. A reliability engine may be configured to collect operation or built in self test data of thermal output and current leakage and historical operation time for a group of equivalent processor cores configured for the same purpose. Collected data may be applied to a weighted function to determine priorities for each equivalent processor core in the group. The reliability engine may rearrange a virtual processor identification translation table according to the priorities of the equivalent processor cores. A high level operating system may issue a process request specifying a processor core and the specified processor core may be translated to a different processor core according to the order of processor cores dictated by the priorities.
