Abstract :
Recovery procedures involving time redundancy in the form of instruction retries and program rollbacks have proved to be very effective against transient failures in computer systems. A class of such recovery procedures is presented and analyzed here, and the parameters of each procedure are determined so that the system´s operation is optimized. These procedures are then compared in order to select the most appropriate one for given system parameters.
