Hi Jiajun, all,
Sorry if I didn't explain myself clearly. What you are explaining is great. I am already using it, successfully checkpointing both serial and MPI applications. My idea is however going a step further. Slurm configuration ( https://computing.llnl.gov/linux/slurm/slurm.conf.html , parameter CheckpointType) allows to specify a checkpointing mechanism. This can be employed by Slurm commands and Slurm API to perform checkpoint-based operations, such making a checkpoint or restarting it. It is also an advantage to the final user, as he doesn't need to employ an specific script but standard Slurm commands to submit and checkpoint his jobs. Looking at the Slurm source code and documentation, I got the impression that DMTCP was not supported out-of-the-box. So my question is whether you know how to integrate both this way.
