dmtcp_restart -- restart processes from given checkpoint images.

Synopsis

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

Description

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

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 --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').

-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

--run-as-root

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

--help

Print this message and exit.

--version

Print version information and exit.
