dear all,
I have tried to checkpoint mpi application using dmtcp but I failed with
the error message as follows :
[40000] WARNING at kernelbufferdrainer.cpp:124 in onTimeoutInterval;
REASON='JWARNING(false) failed'
_dataSockets[i]->socket().sockfd() = 9
buffer.size() = 0
WARN_INTERVAL_SEC = 10
Message: Still draining socket... perhaps remote host is not running under
DMTCP?

I use this sbatch script to submit job :

I also have tried using --rm option in dmtcp_launch but it doesn't work and
no output at all.
anybody tell me how to solve this please ? I need help

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
