A method for facilitating adaptive frequency in a processor having a plurality of cores. The method can include conducting tests on the processor; determining, via the processor testing system, default parameters for operating one or more of the cores, wherein the default parameters are based on results of the tests and cause one or more of the cores to operate within production yield goals of the processor; determining alternative parameters for operating one or more of the cores, wherein the alternative parameters are based on results of the test and cause one or more of the cores to operate outside production yield goals of the processor, and wherein the alternative parameters are usable to reconfigure one or more of the cores after an initial operation per the default parameters; and writing the default parameters and the alternative parameters to a production data storage of the processor.

Adaptive frequency optimization in processors

A processor can have a plurality of cores. A first core processor of a first core can read one or more values of a default parameter set. The first core can be operated in accordance with a first operating characteristic based, at least in part, on the one or more values of the default parameter set. The first core processor can receive an indication to change the operating characteristic of the first core processor. In response to receiving the indication to change the operating characteristic, a signal can be issued to the first core processor to reset. In response to the reset, the first core processor can read one or more values of an alternative parameter set. The first core processor can then be operated in accordance with a second operating characteristic based, at least in part, on the one or more values of the alternative parameter set.

A system for monitoring a computer software system includes a first user actuated tuning knob for allocating space in memory for performance monitoring; a second user actuated tuning knob for a specifying time out value for in-flight units of work; and a transaction monitor responsive to the first and second user actuated tuning knobs for accumulating in synonym chain cells in the allocated space timing statistics for a plurality of in-flight units of work.
