Edit
What I am really looking for is a way to emulate SLURM, something interactive and reasonably user-friendly that I can install.
Original post
I want to test drive some minimal examples with SLURM, and I am trying to install it all on a local machine with Ubuntu 16.04. I am following the most recent slurm install guide I could find, and I got as far as "start slurmd with sudo /etc/init.d/slurmd start".
[....] Starting slurmd (via systemctl): slurmd.serviceJob for slurmd.service failed because the control process exited with error code. See "systemctl status slurmd.service" and "journalctl -xe" for details.
failed!
I do not know how to interpret the systemctl log:
● slurmd.service - Slurm node daemon

lsb_release -a gives the following. (Yes, I know, KDE Neon is not exactly Ubuntu, strictly speaking.)
o LSB modules are available.

Unlike the guide said, I used my own user name, wlandau, and I made sure to chown /var/lib/slurm-llnl and /var/run/slurm-llnl to me. Here is my /etc/slurm-llnl/slurm.conf.

Follow-up
After rewriting my slurm.conf with the help of @damienfrancois, slurmd starts now. But unfortunately, sinfo hangs when I call it, and I get the same error message as before.
$ sudo /etc/init.d/slurmctld stop
[ ok ] Stopping slurmctld (via systemctl): slurmctld.service.
$ sudo /etc/init.d/slurmctld start
[ ok ] Starting slurmctld (via systemctl): slurmctld.service.
$ sinfo
slurm_load_partitions: Unable to contact slurm controller (connect failure)
$ slurmd -Dvvv
slurmd: fatal: Frontend not configured correctly in slurm.conf. See man slurm.conf look for frontendname.
Then I tried restarting the daemons, and slurmd failed to start all over again.
$ sudo /etc/init.d/slurmctld start
[....] Starting slurmd (via systemctl): slurmd.serviceJob for slurmd.service failed because the control process exited with error code. See "systemctl status slurmd.service" and "journalctl -xe" for details.
failed!
