Hi Basma,
Would you mind re-doing this experiment with DMTCP 2.1 (the latest version)?
You'll find it at: http://sourceforge.net/projects/dmtcp/files/dmtcp-2.x/2.1/
Building it should be easy: ./configure && make
We renamed the way to start. It will now be:
bin/dmtcp_launch mpirun -np 4 -H master,node001,node002,node003
/home/ubuntu/NPB3.3/NPB3.3-MPI/bin/lu.A.4
Then to restart, it should be the same as before:
./dmtcp_restart_script.sh
(Is this the way that you were invoking restart for dmtcp-1.2.5?)
If this still gives you any problems, please do write back.
Best wishes,
- Gene

Date: Fri, 7 Feb 2014 04:37:58 +0200
i am trying dmtcp version 1.2.5 with open mpi
i use a 4 node cluster
when i try to check point and restart an exe that was compiler 4 processes it
works good at checkpoint and at restart it gives me an ""Segmentation fault
(core dumped)" " then it works correctly also at restart
ubuntu@master:~$ dmtcp-1.2.5/bin/dmtcp_checkpoint mpirun -np 4 -H
master,node001,node002,node003 /home/ubuntu/NPB3.3/NPB3.3-MPI/bin/lu.A.4
but when i try to check point and restart an exe that was compiler 16 processes
it works good at checkpoint but at restart it gives this output and hangs . it
stops for ever
ubuntu@master:~$ dmtcp-1.2.5/bin/dmtcp_checkpoint mpirun -np 16 -H
master,node001,node002,node003
/home/ubuntu/NPB3.3/NPB3.3-MPI/bin/lu.A.16
it looks like i am missing a simple detail
here is the output i had :
