PROBLEM TO BE SOLVED: To provide a method and system, for recovering from a failure generated in a computer system. SOLUTION: This method provides service to an asynchronous interrupt in multiple processors PA, PB, PC executing a user program. The user program is executed on a first processor PA, PB, PC, a duplication copy of the user program is executed on a second processor PA, PB, PC, and the asynchronous interrupt is received by both the first and second processors PA, PB, PC. An interrupt service routine is executed on the first processor PA, PB, PC by an agreed system call of the user program executed on the first processor PA, PB, PC, and the interrupt service routine is executed on the second processor PA, PB, PC by an agreed system call of the user program executed on the second processor PA, PB, PC.
