Abstract :
A system architecture called the recovery metaprogram (RMP) is proposed. It separates the application from the recovery software, giving programmers a single environment that lets them use the most appropriate fault-tolerance scheme. To simplify the presentation of the RMP approach, it is assumed that the fault model is limited to faults originating in the application software, and that the hardware and kernel layers can mask their own faults from the RMP. Also, relationships between backward and forward error recovery are not considered. Some RMP examples are given, and a particular RMP implementation is described.<>
