I do not know if it you can checkpoint the job. The checkpointing is done by the script listed in your mom config file as $checkpoint_script. This script, if not modified, will be using the cr_checkpoint command installed by BLCR. The man page for this command lists several ways that the job can be started so it is checkpointable. If the -c had been used on the qsub then Torque would have run the job using the cr_run command from BLCR, but since -c was not specified Torque just ran the job normally. The only way that the $checkpoint_script and/or cr_checkpoint might work is if the job was originally linked with one of the libraries listed in the man page for cr_checkpoint.
