Hello,
I am working on getting a simple hello world program running on through
DMTCP with MPI on the sdsc xsede gordon compute cluster.
DMTCP version: 3.0.0
Open MPI version: 1.6.5
Run script:
export DMTCP_COORD_HOST=$HOSTNAME
export DMTCP_COORD_PORT=7779
dmtcp_coordinator --daemon --exit-on-last
dmtcp_launch --rm --ib mpirun $SCRATCH_PATH/helloworld.py
I can run a coordinator in interactive mode on a node through
*dmtcp_coordinator
*with not trouble and launch with the above script. This checkpoints and
restarts fine, but if I run with *--daemon* and *--exit-on-last* I receive
the following errors:
dmtcp_coordinator starting...
Host: gcn-4-25.sdsc.edu (198.202.100.150)
Port: 7779
Checkpoint Interval: 45
Exit on last client: 1

along with the following as output (they repeat for as many cores as I am
running on.

Not sure if related, but make check give the following error:
*bash: line 0: ulimit: virtual memory: cannot modify limit: Operation not
permitted*
Let me know if more info is needed. Sadly, I cannot provide a VM and do
not have root access, or guest account privileges to provide.
