Hi,
There is: util/readdmtcp.sh ckpt_MYAPP.dmtcp
It shows you the different memory images and a bit more.
But if you want to dig deeper, you would have to extend the
readdmtcp.sh tool yourself.
By the way, for questions of general interest, we prefer to
write to dmtcp-forum so that others may benefit from the answer.
Do you have any objection if I forward this question on reading
the chekcpoint image to dmtcp-forum?
[ SUBMITTER ANSWERED: "Absolutely not." ]
P.S.: You can also find this information and others on the FAQ.
For example:

Thanks,
- Gene
