slurm.el

slurm.el is an Emacs extension allowing to work more easily with the SLURM job scheduling system.

It is composed of two parts:

  1. slurm-script-mode: a minor mode to edit job submission scripts;
  2. slurm-mode: a major mode allowing interaction with SLURM.

Installation

Ensure the following dependencies are installed:

Then, just put the following lines in your Emacs initialization file (.emacs or .emacs.d/init.el):

(add-to-list 'load-path "/path/to/slurm.el")
(require 'slurm-mode)
(require 'slurm-script-mode)

slurm-script-mode

slurm-script-mode is automatically activated for shell-scripts containing #SBATCH directives. It can also be manually toggled by running M-x slurm-script-mode.

While in this mode, #SBATCH directives are highlighted and some basic errors are detected (unknown or misspelled keywords, unproperly quoted arguments, ...)

New directives can also be easily inserted using the C-c C-d binding, which proposes completion on the keywords.

Example of slurm-script-mode

slurm-mode

Basic usage

Just run M-x slurm to see a list of all SLURM jobs on the cluster.

slurm.el defines several views to present SLURM information. Each view first presents the command line which have been used to obtain the information presented.

In all views, the following bindings are available:

  • h: show Help
  • g: refresh view

Views

The following key bindings can be used to switch between views:

  • j: Jobs list (default view)
  • p: Partitions list
  • i: cluster Information

Jobs list

This view displays the list of all jobs managed by SLURM on the cluster, as obtained with the squeue command.

The jobs list can be manipulated using the following bindings:

  • /: filter the jobs list by:

    • u: User;
    • p: Partition.
  • s: sort the jobs list by:

    • u: User;
    • p: Partition;
    • P: job Priority;
    • d: use the Default sorting order;
    • c: Customize sorting order by specifying a suitable argument for the -S switch of squeue.

    Giving this command a prefix argument reverses the sorting order. For example, C-u s u sorts by user in reverse alphabetical order.

A few operations can be done from this view:

  • RET: show job details, as obtained with the scontrol show job JOBID command.

  • U: show User details on the job submitter (using the finger USER command).

  • k or d: Kill job by issuing the scancel JOBID command.

  • e or u: Edit (or Update) job.

    In this mode, job submission parameters can be interactively updated (as could be done using the scontrol update job JOBID command). Each parameter is presented on its own line. After editing a line, pressing

    • C-c C-c validates the changes (on the current line only), or
    • C-c C-q cancels the changes and returns to the previous view.

Partitions list

This view displays a list of all partitions on the cluster, as obtained with the scontrol show partition command.

While in this view, pressing RET allows you to access various details about the selected partition state, as obtained using the sinfo command.

Cluster information

This view displays details on the current cluster state, as obtained with the sinfo command.

Customization

Some variables can be set to customize slurm-mode's behaviour:

  • slurm-display-help: if non-nil, slurm-mode displays an help message at the top of the screen;

  • slurm-filter-user-at-start: if non-nil, the initial jobs list is filtered to show only jobs owned by the current user.

  • slurm-script-directive-face: face name to use for #SBATCH directives in job submission scripts.

  • slurm-squeue-format: the list of fields to display in the jobs list.

All these variables can be customized via M-x customize-group RET slurm RET.
