1. A method, comprising: storing in a readable non-volatile memory of a multicore processor integrated circuit device, that stores an identification of the multicore processor integrated circuit device, information expressive of at least one determined operating characteristic for each individual one of a plurality of processor cores that comprise the multicore processor integrated circuit device; and during one of system boot or initial program load time, reading the information from the non-volatile memory and loading machine state registers of the multicore processor integrated circuit device with the information expressive of the at least one of the determined operating characteristics for each individual one of the plurality of processor cores, the machine state registers being connected with an interface of the multicore processor integrated circuit device for being interrogated by a supervisor program that identifies system resources for an operating system for scheduling program tasks to individual ones of the processor cores.
