BLCR or DMTCP should both be able to checkpoint a single node job (single or multi threaded) straight out of the box; you won't need to recompile any of your binaries.
DMTCP does not require any kernel modules, and so you might find that easier going if you are on a more recent kernel than BLCR supports. (DMTCP also seems to do a better job handling MPI jobs than BLCR does, if you care about those.) Thanks, Guy -- Dr. Guy Coates
