The Provisions of Recoverable Interfaces

Lookup NU author(s): Emeritus Professor Tom Anderson, Professor Pete Lee



The recovery block scheme has been proposed as one method of providing fault tolerant software, and is dependent on the availability of recoverable interfaces so that any damage caused by an erroneous program can be repaired by backward error recovery. However, it is clear that the interface provided by the hardware in any particular system will contain unrecoverable objects. This paper investigates a method of structuring a system into multiple levels so that a level of software can "hide" the unrecoverable features of an interface and provide a new interface with recoverable objects to programs needing facilities for backward error recovery. The paper discusses this organisation of recovery in such a system.
