OPTIONS

 

Connecting to the DMTCP Coordinator

-h, --coord-host hostname (environment variable DMTCP_COORD_HOST)

 Hostname where dmtcp_coordinator is run (default: localhost) 

-p, --coord-port port (environment variable DMTCP_COORD_PORT)

 Port where dmtcp_coordinator is run (default: 7779) 

--port-file filename

 File to write listener port number. (Useful with --coord-port 0,which is used to assign a random port)

-j, --join

 Join an existing coordinator, raise error if one doesn't already exist

--new-coordinator

 Create a new coordinator at the given port. Fail if one already exists on the given port. The port can be specified with --coord-port,or with environment variable DMTCP_COORD_PORT. If no port is specified, start coordinator at a random port (same as specifying port '0').

--no-coordinator

 Execute the process in stand-alone coordinator-less mode.
Use dmtcp_commandor --intervalto request checkpoints.

-i, -interval seconds (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. Not allowed if --joinis specified

 

Checkpoint image generation

--gzip, --no-gzip (environment variable DMTCP_GZIP=[01])

 Enable/disable compression of checkpoint images (default: 1 (enabled))
WARNING: gzip adds seconds. Without gzip, ckpt is often < 1s

--ckptdir path (environment variable DMTCP_CHECKPOINT_DIR)

 Directory to store checkpoint images (default: curr dir at launch) 

--ckpt-open-files

 Checkpoint open files and restore old working dir. (default: do neither) 

--checkpoint-open-files

 Deprecated. Use --ckpt-open-filesinstead.

--ckpt-signal signum

 Signal number used internally by DMTCP for checkpointing (default: 12) 

--ckpt-signal signum

 Deprecated. Use --ckpt-signalinstead.

 

Enable/disable plugins

--with-plugin plugins (environment variable DMTCP_PLUGIN)

 Colon-separated list of DMTCP plugins to be preloaded with DMTCP. (Absolute pathnames are required.)

--batch-queue, --rm

 Enable support for resource managers (Torque PBS and SLURM). (default: disabled)

--ptrace

 Enable support for PTRACE system call for gdb/strace etc. (default: disabled) 

--modify-env

 Update environment variables based on the environment on the restart host (e.g., DISPLAY=$DISPLAY). This can be set in a file dmtcp_env.txt. (default: disabled)

--ib, --infiniband

 Enable InfiniBand plugin. (default: disabled) 

--disable-alloc-plugin (environment variable DMTCP_ALLOC_PLUGIN=[01])
