Lightweight Memory Checkpointing [PDF]
2015 45th Annual IEEE/IFIP International Conference on Dependable Systems and Networks, 2015 Memory check pointing is a pivotal technique in systems reliability, with applications ranging from crash recovery to replay debugging. Unfortunately, many traditional memory check pointing use-cases require high-frequency checkpoints, something for which existing application-level solutions are not well-suited.
