Abstract: Aspects include computing devices, systems, and methods for adjusting the assignment of tasks to processor cores in a multi-core processing system. In an aspect, a reliability engine may be configured to determine priorities for a selected cluster of processor cores according to various methods depending on whether the selected processor cores are inactive and/or whether the computing device is in a cold boot state. The reliability engine may be configured to determine the priorities according to a round robin scheme, a pseudorandom scheme, from stored and/or collected operation data, or from stored and/or collected built in self test data in response to various activities and boot states of the processor cores. The reliability engine may rearrange a virtual processor identification translation table according to the priorities of the equivalent processor cores.
