The option --enable-front-end to configure is also needed to emulate<br>
really large cluster:<br>

This option is enabled only in the slurmctld daemon that is contained in<br>
the slurm-wlm-emulator package that is not intended to be used for batch<br>
jobs.<br>
<br>
vagrant@ubuntu-bionic:~$ grep 'No front end nodes defined' /usr/sbin/slurmctld-wlm-emulator<br>
Binary file /usr/sbin/slurmctld-wlm-emulator matches<br>
vagrant@ubuntu-bionic:~$ grep 'No front end nodes defined' /usr/sbin/slurmctld-wlm<br>
vagrant@ubuntu-bionic:~$<br>
<br>
It can be possible that Umut installed slurm-wlm-emulator package<br>
together with the regular package and the emulated daemon was picked by<br>
the alternatives system.<br>
<br>
