Checkpointing is an important method for providing fault tolerance, load balancing, process migration, periodic backup, and many other functions. It is also the basic tool used in CAPE, a paradigm which aims at distributing the execution of a program on a distributed-memory environment. This paper presents the new approach to checkpointer and the original optimization on checkpoint structure we have implemented and evaluated to make incremental checkpointing more efficient and more appropriate, especially for CAPE.
