sattach(1) SLURM Commands sattach(1) 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. INPUT ENVIRONMENT VARIABLES
Upon startup, salloc will read and handle the options set in the following environment variables. Note: Command line options always over- ride 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. EXAMPLES

SLURM(1) Slurm system SLURM(1) NAME
slurm - SLURM system overview. DESCRIPTION
The Simple Linux Utility for Resource Management (SLURM) is an open source, fault-tolerant, and highly scalable cluster management and job scheduling system for large and small Linux clusters. SLURM requires no kernel modifications for its operation and is relatively self-con- tained. As a cluster resource manager, SLURM has three key functions. First, it allocates exclusive and/or non-exclusive access to resources (compute nodes) to users for some duration of time so they can perform work. Second, it provides a framework for starting, exe- cuting, and monitoring work (normally a parallel job) on the set of allocated nodes. Finally, it arbitrates contention for resources by managing a queue of pending work. Optional plugins can be used for accounting, advanced reservation, gang scheduling (time sharing for parallel jobs), backfill scheduling, resource limits by user or bank account, and sophisticated multifactor job prioritization algorithms. SLURM has a centralized manager, slurmctld, to monitor resources and work. There may also be a backup manager to assume those responsibili- ties in the event of failure. Each compute server (node) has a slurmd daemon, which can be compared to a remote shell: it waits for work, executes that work, returns status, and waits for more work. An optional slurmDBD (SLURM DataBase Daemon) can be used for accounting pur- poses and to maintain resource limit information. Basic user tools include srun to initiate jobs, scancel to terminate queued or running jobs, sinfo to report system status, and squeue to report the status of jobs. There is also an administrative tool scontrol available to monitor and/or modify configuration and state infor- mation. APIs are available for all functions. SLURM configuration is maintained in the slurm.conf file. Man pages are available for all SLURM commands, daemons, APIs, plus the slurm.conf file. Extensive documenation is also available on the internet at <http://www.schedmd.com/slurmdocs/>. COPYING
