Mechanisms for Recoverable-Persistence in a Single Address Space

In this paper we consider mechanisms for supporting recoverable-persistence in a single address space memory model. In particular, we consider a memory management system, MMS, for a persistent single address space and show how the operations MMS supplies can be exploited by applications to make their state recoverable-persistent. To this end, we present detailed examples of application-level management of recoverable-persistence. The resulting scenario appears to be particularly attractive because of its modularity. Moreover, additional complexity is not introduced at the lower layers of the system and applications that do not need recoverable-persistence need not be penalised.
