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.
