NAME¶
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, --host hostname (environment variable
DMTCP_HOST)
-
Hostname where dmtcp_coordinator is run (default: localhost)
- -p, --port port (environment variable
DMTCP_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 --port, or with
environment variable DMTCP_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.
