ABSTRACT:
A method is provided for synchronizing distributed processors. The method comprises determining a desired number of offset values between two processors, wherein each processor comprises a quartz crystal, determining parameters of a regression line, wherein the regression line is a function of the offset values over the desired number of offsets, and adjusting a synchronization interval according to the parameters.
