Hi
I want to checkpoint an MPI application and for that i installed DMTCP check
pointing tool. It is configured well. But when i checkpoint my application it
is showing error. I am using dmtcp-1.2.6.tar.gz package.
For checkpointing application i opened a seperate terminal and typed-
dmtcp_coordinator
DMTP coordinator started showing-
dmtcp_coordinator starting...
Port: 7779
Checkpoint Interval: 10
Exit on last client: 0
Type '?' for help.
Then i opened another terminal and there i typed
dmtcp_checkpoint ./runme_intel64 (name of the executable)
As i type the above command, it shows the following error-
WARNING at kernelbufferdrainer.cpp:100 in onTimeoutInterval;
REASON='JWARNING(false) failed'
_dataSockets[i]->socket().sockfd() = 5
buffer.size() = 0
WARN_INTERVAL_SEC = 10
Message: Still draining socket... perhaps remote host is not running under
DMTCP?
Please help me in resolving it.
Thanks & Regards
Manisha Chauhan
