EN This paper presents a new checkpoint recovery protocol for Distributed Shared Memory (DSM) systems with read-write objects. It is based on independent checkpointing integrated with a coherence protocol for causal consistency model. That integration results in high availability of shared objects and ensures fast restoration of consistent state of the DSM in spite of multiple node failures, introducing little overhead. Moreover, in case of network partitioning, the extended protocol ensures that all the processes in majority partition of the DSM system can continuously access all the objects.
