ABSTRACT:
A method and apparatus to insert special instruction. At least one of the illustrative embodiments is a method comprising converting a first representation of a computer program to a second representation, and inserting into the second representation a special instruction not needed to implement functionality in the first representation. The special instruction gives duplicate copies of the computer program executed in different processors an opportunity to service external asynchronous interrupts.
