Hello DMTCP forum,
I’m trying to checkpoint a Gaussian calculation using Linda, the message
passing system they use. This test job is using two nodes connected with
InfiniBand and is run through SLURM. I’m using the start_coordinator script as
suggested. The job is started via:
start_coordinator -i 43200
dmtcp_launch --with-plugin libdmtcp_infiniband.so --batch-queue —infiniband
--ckpt-open-files --modify-env g09_linda PD1_zmat.g09
The job then crashes shortly after starting with:
[53000] WARNING at socketconnection.cpp:187 in TcpConnection;
REASON='JWARNING(false) failed'
type = 2
Message: Datagram Sockets not supported. Hopefully, this is a short lived
connection!
[53000] WARNING at socketconnection.cpp:187 in TcpConnection;

[55000] ERROR at ssh.cpp:277 in prepareForExec; REASON='JASSERT(commandStart <

commandStart = 3
nargs = 33
argv[commandStart] = -n
Message: failed to parse ssh command line
bash (55000): Terminating...
Any thoughts or suggestions are greatly appreciated.
Best regards,
Rob
