SlurmCommander

Description

SlurmCommander is a simple, lightweight, no-dependencies text-based user interface (TUI) to your cluster. It ties together multiple slurm commands to provide you with a simple and efficient interaction point with slurm.

Installation does not require any special privileges or environment. Simply download the binary, fill out a small config file and it's ready to run.

You can view, search, analyze and interact with:

• Job queue - view, search, inspect, ssh to nodes, issue commands to jobs etc.
• Job history - browse, search and inspect past jobs
• Edit and submit jobs from predefined templates (can be your own or group/site ones)
  • In the config file, set the templatedirs list of directories where to look for .sbatch templates and their .desc description files
• Examine state of cluster nodes and partitions

Installation

SlurmCommander does not require any special privileges to be installed, see instructions below.

Hard requirement: json-output capable slurm commands

Regular users

1. Download the pre-built binary
2. Download the annotated config file
3. Edit the config file, follow instructions inside
4. Create scom directory in your $HOME and place the edited config there: mkdir $HOME/scom
5. Run

Site administrators

Instructions are same as for the regular users, with one minor perk. Place the config file in /etc/scom/scom.conf to be used as global configuration source for all scom instances on that machine.

NOTE: Users can still override global configuration options by changing config stanzas in their local $HOME/scom/scom.conf

Usage tips

SlurmCommander is developed for 256 color terminals (black background) and requires at least 185x43 (columns x rows) to work.

• If you experience funky colors on startup, try setting your TERM environment variable to something like xterm-256color.
• If you get a message like this: FATAL: Window too small to run without breaking view. Have 80x24. Need at least 185x43., check your terminal resolution with stty -a and try resizing the window or reduce the font.

[pja@ SlurmCommander-dev]$ [DEBUG=1] [TERM=xterm-256color]./scom -h
Welcome to Slurm Commander!

Usage of ./scom:
  -d uint
        Jobs history fetch last N days (default 7)
  -t uint
        Job history fetch timeout, seconds (default 30)
  -v    Display version

To run in debug mode, set DEBUG env. variable. You will see an extra debug message line in the user interface and scom will record a scdebug.log file with (lots of) internal log messages.

Tested on:

• slurm 21.08.8
• slurm 22.05.5
