This paper presents a checkpointing scheme that was implemented in a parallel library that runs on top of CHIMP/MPI. The main goals of the checkpointing mechanism are portability and efficiency. It runs on every platform supported by MPI in a machine-independent way. The scheme allows the migration of checkpoints and offers a flexible recovery mechanism based on data-reconfiguration. Some performance results will be presented at the end of the paper together with some techniques that can be used to increase the efficiency of the checkpointing mechanism
