NAME

dmtcp_restart -- restart processes from given checkpoint images.

SYNOPSIS

dmtcp_restart [OPTIONS] ckpt1.dmtcp [ckpt2.dmtcp...]

DESCRIPTION

dmtcp_restart restarts processes from the given checkpoint image files. Note that DMTCP also writes out a shell script for restarting all processes. It is written in the current directory of the coordinator by default.

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.
