NAME¶
sattach - Attach to a SLURM job step.
SYNOPSIS¶
sattach [
options] <jobid.stepid>
DESCRIPTION¶
sattach attaches to a running SLURM job step. By attaching, it makes available
the IO streams of all of the tasks of a running SLURM job step. It also
suitable for use with a parallel debugger like TotalView.
OPTIONS¶
- -h, --help
- Display help information and exit.
- --input-filter[=]<task number>
- --output-filter[=]<task number>
- --error-filter[=]<task number>
- Only transmit standard input to a single task, or print the
standard output or standard error from a single task. The filtering is
performed locally in sattach.
- -l, --label
- Prepend each line of task standard output or standard error
with the task number of its origin.
- --layout
- Contacts the slurmctld to obtain the task layout
information for the job step, prints the task layout information, and then
exits without attaching to the job step.
- --pty
- Execute task zero in pseudo terminal. Not compatible with
the --input-filter, --output-filter, or
--error-filter options. Notes: The terminal size and resize events
are ignored by sattach. Proper operation requires that the job step be
initiated by srun using the --pty option. Not currently supported on AIX
platforms.
- -Q, --quiet
- Suppress informational messages from sattach. Errors will
still be displayed.
- -u, --usage
- Display brief usage message and exit.
- -V, --version
- Display SLURM version number and exit.
- -v, --verbose
- Increase the verbosity of sattach's informational messages.
Multiple -v's will further increase sattach's verbosity.
Upon startup, salloc will read and handle the options set in the following
environment variables. Note: Command line options always override environment
variables settings.
- SLURM_EXIT_ERROR
- Specifies the exit code generated when a SLURM error occurs
(e.g. invalid options). This can be used by a script to distinguish
application exit codes from various SLURM error conditions.
