I don't see anything specific right now but googl'ing for "linux
checkpoint restart" comes up with a few links, most prominent is
Berkeley Labs Checkpoint/Restart (BLCR):
https://ftg.lbl.gov/CheckpointRestart/CheckpointRestart.shtml

Another option I heard about, though never tried, is to take VMware
snapshot - run your calc in a VMware virtual machine and take a
snapshot of the entire VM. Then if it (or its host) crashes for some
reason you should be able to restore it to the checkpointed state.

Hope this helps,
