[slurm-users] New checktopology tool: Check consistency of /etc/slurm/topology.conf with nodelist in /etc/slurm/slurm.conf

[Ole Holm Nielsen]

Hi Slurm users,

When removing dead nodes or adding new nodes, I've too often made the 
mistake of forgetting to update correctly the /etc/slurm/topology.conf file.

Therefore I wrote a simple "checktopology" tool to check the consistency 
of /etc/slurm/topology.conf with the nodelist in /etc/slurm/slurm.conf 
(as presented by the sinfo command).  It's available from my Github 
project at https://github.com/OleHolmNielsen/Slurm_tools/tree/master/nodes

An example output is:

$ checktopology
Extract nodelist from /etc/slurm/topology.conf
