Hi Ankit,
Sorry for not getting back to you sooner. As you have already figured out,
it's a good idea to use the dmtcp restart script to restart distributed
computations. The alternative is to use the ckpt images directly, but then
you have to log on to the remote machine and execute dmtcp_restart from
there.
