{subsection: Checkpointing in Condor's vanilla universe} -1: Register a signal handler for SIGTSTP; it should send SIGTSTP to the running "real" job. +1: Register a signal handler for SIGTERM; it should send SIGTSTP to the running "real" job. +1: Register a signal handler for SIGTSTP; it should send SIGTSTP to the running +"real" job. (This will probably be unused, but is included to offer an option that is more similar to the standard universe.) 2: Register a signal handler for SIGUSR2; it should send SIGUSR2 to the running "real" job. (As of July, 2012, this will never be used, but we anticipate adding support for periodic checkpoints in the vanilla universe.) 3: Is the checkpoint file ("my-real-job.ckpt") present? Then the arguments are "-_condor_restart my-real-job.ckpt -_condor_relocatable". Otherwise the arguments are "-_condor_ckpt my-real-job.ckpt". 3: Start your "real" job
