| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Checkpointing is a technique to give a fault tolerance to applications. Some research proposed ways to checkpoint arbitrary unmodified applications transparently. Previous study shows that Non-volatile DIMM(NVDIMM) can be used for storing checkpoint states to avoid depending on external non-volatile storages which is hundreds times slower than DRAM. However, every checkpoint techniques still copy process states from DRAM to non-volatile storages and it is a major bottleneck. This paper proposes NDCKPT, which maps applications into NVDIMM directly to reduce copying on checkpointing, and duplicate memory space and page table structure to ensure consistency of checkpointing. We implemented NDCKPT on Linux kernel and evaluated with Optane DC Persistent Memory. We found NDCKPT overhead for small applications which consume approximate 1MB memory can be less than 1% even the checkpoint frequency is 100 ms. For large applications which use hundreds megabytes of memory, the slowdown comes from execution on NVDIMM is dominant, and the execution time can be 2 to 3 times longer than on DRAM. However, additional slowdown by checkpoints with 20 to 30 seconds interval is around 10% of time on NVDIMM without checkpoints. |
