Slurm

So recently I was tasked to set up a Slurm cluster for bioinformatics workloads, and I thought it would be a good idea to share some notes about the installation and configuration process.

So in short, before we start, what is Slurm?

Slurm is an open-source, fault-tolerant, and highly scalable cluster management and job scheduling system for large and small Linux clusters. It is used by many of the world’s supercomputers and computer clusters.

Netcat

I heard too many times a work colleague, or a third-party vendor telling me “there is something wrong on the network here”, or “This port isn’t open!”.

You can use websites to try to test for open ports, a quick Google search should yield you a couple good results, but sometimes that is not enough.

Let’s suppose you followed my other post about restricting source address with iptables, in this case those random web tools won’t help you, so you use nmap!
