Abstract
A method is presented for enabling application-level software to normalize processor clock values within a multiprocessor data processing system. A first processor number associated with a first processor is obtained such that the first processor executes one or more instructions for obtaining the first processor number. Subsequent to obtaining the first processor number, a processor clock value is obtained such that the processor clock value is associated with a processor that executes one or more instructions for obtaining the processor clock value. Subsequent to obtaining the processor clock value, a second processor number associated with a second processor is obtained such that the second processor executes one or more instructions for obtaining the second processor number. If the first processor number and the second processor number are equal, then the first processor number is used to retrieve a compensation value for a normalization operation on the processor clock value.
