dmtcp_restart -- restart processes from given checkpoint images.


dmtcp_restart [Options] ckpt1.dmtcp [ckpt2.dmtcp...]


dmtcp_command is a tool to send user commands to the dmtcp_coordinator remotely.


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 --port 0, which is used to assign a random port)
-j, --join
Join an existing coordinator, raise error if one doesn't already exist
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').
-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 --join is specified

Other options

Allow root to run dmtcp_restart and disable uid checking. (default: disabled)
--no-strict-uid-checking (environment variable DMTCP_DISABLE_UID_CHECKING)
Disable uid checking for the checkpoint image. This allows the checkpoint image to be restarted by a different user than the one that created it.
--ckptdir path (environment variable DMTCP_CHECKPOINT_DIR)
Directory to store checkpoint images (default: use the same directory used in previous checkpoint)
--tmpdir path (environment variable DMTCP_TMPDIR)
Directory to store temporary files (default: $TMDPIR/dmtcp-$USER@$HOST or /tmp/dmtcp-$USER@$HOST)
-q, --quiet (or set environment variable DMTCP_QUIET = 0, 1, or 2)
Skip NOTE messages; if given twice, also skip WARNINGs
Print this message and exit.
Print version information and exit.
