Abstract
A method and system of presenting an interrupt request to processors executing in lock step. At least some of the illustrative embodiments are computer systems comprising a first processor configured to execute a program, a second processor configured to execute a duplicate copy of the program in lock step with the first processor, and a logic device coupled to the processors. The logic device is configured to present an interrupt request to the processors when the processors are at substantially the same computational point in the program.
