Abstract	Computer clusters are today the reference architecture for high-performance computing. The large number of nodes in these systems induces a high failure rate. This makes fault tolerance mechanisms, e.g. process checkpoint/restart, a required technology to effectively exploit clusters. Most of the process checkpoint/restart implementations only handle volatile states and do not take into account persistent states of applications, which can lead to incoherent application restarts. In this paper, we introduce an efficient persistent state checkpoint/restoration approach that can be interconnected with a large number of file systems. To avoid the performance issues of a stable support relying on synchronous replication mechanisms, we present a failure resilience scheme optimized for such persistent state checkpointing techniques in a distributed environment. First evaluations of our implementation in the kDFS distributed file system show the negligible performance impact of our proposal.
