Abstract
A method and system of determining the execution point of programs executed in lock step. At least some of the illustrative embodiments are computer systems comprising a first processor that executes a program, and a second processor that executes a duplicate copy of the program in lock step with the first processor. After receipt of a duplicate copy of an interrupt request by each processor, the first processor determines the execution point in its program relative to the execution point of the duplicate copy of the program executed by the second processor.
