Efficient incremental checkpoint based on hybrid page

Abstract

Modern computer systems are suffering from various failures and are increasingly prone to error. This paper introduces a high efficient incremental checkpoint mechanism for fault tolerance. By leveraging the new hardware support for various page sizes, we make dynamic transformation between different sized pages and thus achieve the best balance of overhead between modification tracking and data dumping in incremental checkpoint. Experiments show that our new checkpoint mechanism could achieve an average speedup of 2.2x with the space overhead of 34% over traditional incremental checkpoint, showing great potential to be widely adopted.
