Abstract
A method and system of bringing processors to the same computational point. At least some of the illustrative embodiments are computer systems comprising a first processor executing a program, a second processor executing a duplicate copy of the program (but at different computational points in the program), and a shared main memory coupled to the first and second processors. When the processors each receive duplicate copies of an interrupt request, the processors are configured to bring their respective programs to the same computational points prior to servicing the interrupt request.
