.SS Connecting to the DMTCP Coordinator
.TP
\fB\-h\fP, \fB\-\-coord\-host\fP \fIhostname\fP (environment variable DMTCP_COORD_HOST)
 Hostname where dmtcp_coordinator is run (default: localhost) 
.PP
.TP
\fB\-p\fP, \fB\-\-coord\-port\fP \fIport\fP (environment variable DMTCP_COORD_PORT)
 Port where dmtcp_coordinator is run (default: 7779) 
.PP

(Useful with \fB\-\-port 0\fP,
which is used to assign a random port) 
.PP
.TP
\fB\-j\fP, \fB\-\-join\fP
 Join an existing coordinator, raise error if one doesn\&'t 
already exist 
.PP
.TP
\fB\-\-new\-coordinator\fP
 Create a new coordinator at the given port. Fail if one 
already exists on the given port. The port can be specified 
with \fB\-\-coord\-port\fP,
or with environment variable DMTCP_COORD_PORT. 
If no port is specified, start coordinator at a random port (same 
as specifying port \&'0\&'). 
.PP
.TP
\fB\-i\fP, \fB\-interval\fP \fIseconds\fP (environment variable DMTCP_CHECKPOINT_INTERVAL)
 Time in seconds between automatic checkpoints. 
0 implies never (manual ckpt only); if not set and no env var, 
use default value set in dmtcp_coordinator or dmtcp_command.

is specified
