I stumbled across CRIU (Checkpoint/Restore In Userspace) https://criu.org/Main_Page <https://criu.org/Main_Page> a couple of weeks ago. I have not utilized it yet it; it's on my ToDo list. They claim that it’s packaged with most distress; I checked RHEL/CentOS and it was there. Be careful of package/kernel versions; i.e a good reason to go with the version included in your distro. BLCR was last updated January 2013; back in the day, it worked well enough for simpler apps; complicated MPI apps was less so.
