Hi Kapil, Thank you a lot for your reply. I will comment below your answer.

But when I do that I have the follow message: --------- $dmtcp_launch -i 2 ./applic dmtcp_coordinator starting... Host: edson (127.0.1.1) Port: 7779 Checkpoint Interval: 2 Exit on last client: 1 Backgrounding... -------------- The file is checkpointed, but shouldn't I see the printf's of the file applic.c, as for sample :*** dmtcp_checkpoint: This program has now invoked a checkpoint. It will resume its execution next."? About my others questions (2 and 3), I will try do the same with a previous DMTCP version. Thank you! Edson
