Abstract

This paper presents a new transparent, incremental, concurrent checkpoint mechanism for embedded multi-core systems. It allows the checkpointed process (also called checkpointee) to continue running without stopping while checkpoints are set to a large extent. Through tracing TLB misses to block the accesses to target memory pages first time while dumping memory pages (the most time-consuming step when setting a checkpoint). At that time, a kernel thread, called checkpointer, copies the memory access target pages to the designated memory buffer for constructing a consistent state of the checkpointee, and then resumes the memory accesses. From the experimental results, in contrast to a traditional concurrent checkpoint system, the proposed mechanism reduces the downtime of the checkpointed process by more than 10.1
