Hi Everyone!
I have a question: What is the expected behaviour of DMTCP when I use DMTCP
on a MPI application that exchanges messages with another application that
is not running on dmtcp_launch?
I ask because I have an error when I execute a MPI application that
exchanges message via TCP with another application. Both application are
running on my cluster. But I only need to make the checkpoint the MPI
application. The error is the following:
========
WARNING at kernelbufferdrainer.cpp:120 in onTimeoutInterval;
REASON='JWARNING(false) failed'
_dataSockets[i]->socket().sockfd() = 15
buffer.size() = 1059
WARN_INTERVAL_SEC = 10
Message: Still draining socket... perhaps remote host is not running under
DMTCP?
=======
Thanks!
Edson
