How to checkpoint-restart R jobs in batch mode?
...ne.
However, I am looking for a solution when this kind of facility is not
available on the cluster, for example , by modifying the code so that the
job can checkpoint and restart by itself.
Does anyone have any experience or idea of doing so? Any help would be
greatly appreciated.
