ABSTRACT:
Methods, systems and computer program products for CPU signaturing to aide in performance analysis. Exemplary embodiments include a performance analysis method including identifying a workload having one or more testcases, assigning a CPU signature to each of the one or more testcases, calling a CPU signature application programming interface that toggles the CPU to generate the CPU signature, passing four parameters to the CPU signature application programming interface, prior to running each of the one or more testcases of the workload, generating the CPU signature, dynamically determining a run order of the one or more testcases at a run time of the workload and reviewing performance data during the running of each of the one or more testcases, each of the one or more testcases being identifiable by its respective CPU signature.
