Abstract
A computer implemented method, data processing system, and computer usable code are provided for burn-in testing of a multiprocessor. A process identifies a power management data set for a plurality of processor cores associated with the multiprocessor. The process selects one or more of the plurality of processor cores to form a selected set of processor cores based upon the power management data set. The process initiates a burn-in test across the selected set of processor cores. In response to a determination that all processor cores in the plurality of processor cores have not been selected, the process repeats the above selecting and initiating steps until all the processor cores have been selected.
