Hi Artem, thanks for writing back.
We're using DMTCP-2.0 and Torque-4.1.5.1.
I'm a bit confused as to how to install a dmtcp plugin, or if in fact the
Torque plugin is already installed by default. For example if I start up a
nodes=2:ppn=2 PBS session, my $PBS_NODEFILE may look something like
host1
host1
host2
host2
I then do
dmtcp_launch --rm mpiexec -np 4 ./a.out (4-processor job successfully runs on 2
processors on each of 2 nodes)
dmtcp_command --checkpoint (in a separate window)
dmtcp_command --kill (in a separate window)
dmtcp_restart ckpt*.dmtcp
After the last step, the job successfully restarts, but all 4 processes are now
running on the localhost (host1), nothing is running on host2, and the
$PBS_NODEFILE appears to be ignored.
Thanks for any tips!
Bryan

Hellp, Bryan.
What version of DMTCP/Torque you use?

Yes, that's correct. You'll need to use the DMTCP plugin for Torque.
Artem Polyakov is supporting that, and I'm cc'ing to him. Among other
issues, mount points can change and network addresses can change on restart.
The plugin tries to handle that.
Please let us know if you have any trouble using the Torque plugin.
Best,
