Install Slurm 19.05 on a standalone machine running Ubuntu 20.04
View single_machine_slurm_on_ubuntu.md

Use apt to install the necessary packages:

sudo apt install -y slurm-wlm slurm-wlm-doc

Load file:///usr/share/doc/slurm-wlm/html/configurator.html in a browser (or file://wsl%24/Ubuntu/usr/share/doc/slurm-wlm/html/configurator.html on WSL2), and:

  1. Set your machine's hostname in SlurmctldHost and NodeName.
  2. Set CPUs as appropriate, and optionally Sockets, CoresPerSocket, and ThreadsPerCore. Use command lscpu to find what you have.
  3. Set RealMemory to the number of megabytes you want to allocate to Slurm jobs,
  4. Set StateSaveLocation to /var/spool/slurm-llnl.
  5. Set ProctrackType to linuxproc because processes are less likely to escape Slurm control on a single machine config.

How is git commit sha1 formed
View explanation.md

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry.

Locally, I'm at this commit:

$ git show
commit d6cd1e2bd19e03a81132a23b2025920577f84e37
Author: jnthn <jnthn@jnthn.net>
Date:   Sun Apr 15 16:35:03 2012 +0200

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.

A good commit message looks like this:

Header line: explaining the commit in one line

Body of commit message is a few lines of text, explaining things
in more detail, possibly giving some background about the issue
being fixed, etc etc.

The body of the commit message can be several paragraphs, and
please do proper word-wrap and keep columns shorter than about
