How do I use checkpointing (i.e., stop and later restart a run)?
Set the writecheckpoints option to “1” before doing a run. If the run is stopped for some reason (intentionally or not), it can be restarted by changing the restart option to “1” in the config file and executing the program. DO NOT make any other changes to the config file before attempting a restart, or bad things may happen. See the writecheckpoints and restart options below.
